180° Shutter Angle - Why I don't use it for 50/60p

I explain shutter angle in videography and show why I don't use 180° shutter when shooting in 50/60p for use on a 25p timeline. So many people default to using 180° Shutter angle without really considering the effects it has on playing back at normal speed.
I show some examples of why 360° shutter angle can be a better choice if you're shooting in 50 or 60 frames per second knowing that not all of your shots are going to be slowed down as slow motion content.

[@Richvadar]

This is the most significant video ever done on this topic! Hats off to you and thank you for looking out for us filmmakers!

[@PaulJoy]

Glad it was useful, thanks for letting me know.

[@eplj]

Paul, thanks A LOT for this video. Knowing physics and photography theory, I was really messed up (not to say bothered) that most video theory talks about the 180-degree rule and says that 60 fps is the enemy. *The golden rule should be: to achieve the most realistic motion blur, you must use 1/48~1/60 shutter speed.* This video is 2 years old, but it is still the only one that confirms my theory and finally made me feel like I wasn't crazy. I really don't like seeing the stepping frames on the 24p/30p timeline. Now I can rest in peace with 1/60 and 60 fps.

[@PaulJoy]

Really pleased it makes sense, they key is to think about shutter angle on the timeline and not at time of capture, then it all makes a bit more sense.

[@SergioPellico]

Normally, when I record events where there are parts in a sequence that I will play at 25p or in slow motion, I usually record at 100 shutter speed. But sometime, when I need more light to come in, I have lowered it to 50 shutter speed and have had no problems. Seeing this test I see that I can record at 50 shutter speed and have no problems. Thanks!

[@PaulJoy]

Ah yes, I did mean to mention that advantage of having an extra stop for low light but forgot all about it! Thanks for the reminder.

[@smortonmedia]

This is a great explanation and makes me want to break the 180 shutter rule immediately! I always want to shoot in 60p to have options for slomo but at 1/125th shutter it loses that "cinematic" feel. Until now, I never understood how people were able to achieve that "cinematic look" in both regular playback speeds and then ramp down to slomo while maintaining the same look and feel. So this is incredible, thank you so much

[@PaulJoy]

Excellent, hope it works well for you :)

[@sampsonpictures]

Thank you @@PaulJoy . I'm filming a WW1 Doco, and our reenactments will be shot @ 50P. Doing a test with the DZOFilm Catta ace Zoom Lens on the Panasonic S1 camera via Ninja V (4K Pro Res Raw).

[@PaulJoy]

@@sampsonpictures Sounds exciting, let me know how the test goes.

[@sampsonpictures]

The test went good. Also, I liked your video on the variable filter, as I have the same setup. I was unaware of the gamma shift. My daughter's jersey was yellow but appeared orange with the variable filter. Easy fix in Resolve, but it's good to know. Cheers for that, and I will purchase a couple of ND@@PaulJoy

[@CahyoPrabowo]

The opening scene in Saving Private Ryan using 45 degree (1/192) and 90 degree (1/96) shutter. In an interview, Steven Spielberg said: "You can also see several explosions, and Janusz came up with the idea of shooting with the shutter open to 45 degrees or 90 degrees, which completely negated any blurring. Often, when you see an explosion with a 180-degree shutter it can be a thing of beauty, but a 45-degree shutter looks very frightening."

[@user-xr3cu9hf8c]

This is an awesome explanation about shutter speed and framerate! Thank you so much for making a great video that truly helps everyone!

[@PaulJoy]

Thanks loads for letting me know, much appreciated.

[@PascalVideography]

Wow, very informative video. I never realised that shooting at double of 50p or 60p you actually loosing the smooth motion blur. Your explanation with examples makes perfect sense. Thank you!

[@PaulJoy]

Yup, this one takes a while but once you get it it can be a great way of shooting for normal speed and slowmo shots without compromising the normal speed playback.

[@Nishimachi_Photography]

This is incredibly useful. I haven't used slow mo in any of my videos and I came across this video in my research. I shoot racing cars, so getting slow mo right is going to be crucial. Thanks so much.

[@PaulJoy]

Glad it was useful, just bear in mind that this is all about no compromising footage played back at normal speed, you do get additional motion blur in slow-mo so you'll need to decide if that works okay for the cars.

[@MegaReaso]

That is brilliant. Thank you. Never thought of 360 degree or ) degree shutter. I always shot things twice at different frame rates then in post chose what I needed to slow down. Which took a lot longer.

[@DirtyWindshieldSeries]

Remember when all we had to remember was loading the tape, winding up the cine camera and pressing the trigger to capture a few seconds of film footage that always seemed underexposed in the shade or overexposed in the sunlight with a tint that couldn't be corrected?😂 We've come a long way over the last 45 years. That was a Great Video, explaining Shutter Rates. Your demonstration/example was Spot On! Well Done! Cheers!

[@PaulJoy]

I remember loading tape but thankfully never had to wind up my cameras :) Thanks loads for the feedback.

[@anthonybryantmedia]

I've been blowing my mind on frame rates not just the shutter rule but whether 24,30,60 or 25,50 to use. Dealing with aircraft cabin lighting and strobing, flickering etc I've freally struglled. Whilst you dont cover fps uses in this vide you cleared my head regarding shutter rule. Nicely explained.

[@PaulJoy]

Pleased it helped, dealing with flicker can be nightmare, especially on cameras without variable shutter

[@vahidamini1863]

Thank you so much for the useful explanations✌

[@gustavevilleneuvedehoff-un5459]

Oh, already been here and liked it. Still nice to watch again and confirm my own findings, wish I could like twice :) And the video itself is very nicely done!

[@PaulJoy]

Welcome back :)

[@ronbrotu]

Thanks for taking the time to share this information!

[@PaulJoy]

Glad it was helpful!

[@MartinAaberge]

This was a very well made video! I’ll link to this one in one of my videos where I am talking about this

[@JaronLatona]

THIS. I’ve been developing this understanding for some time and you articulated it perfectly. Each time my mind went, “and what about…?” you immediately shifted to answer the question I had. Think about the underlying theory rather than following dogmatic “rules.” Well done!

[@PaulJoy]

Thanks for sharing your thoughts, as you say it’s often better to understand why rather than just following the rules.

[@mreddieau]

Keep up the great videos Paul

[@PaulJoy]

Thanks

[@theclifbar]

Brilliant and the slider test with the mixer is just perfect. Honestly shocked your channel doesn't have like a million subscribers. Just a matter of time. I wish 48 fps was more commonly available on cameras as it would be perfect for frame dropping to 24 fps (and, of course, shooting a 360 degree shutter!)

[@PaulJoy]

Thanks for the nice comment.

[@JacobTops]

Finally what I was looking for. This man is a professional

[@PaulJoy]

Glad it helped :)

[@electriccatvisualarts2397]

Great insight Paul. I've been experimenting with 60p at 270 degree SA recently for exposure purposes. This is excellent info! Thanks.

[@PaulJoy]

My pleasure, have fun.

[@oddmoviez1602]

Thank you so much for talking about it. As an engineer I've been trying to prove people that if they stick to this rule even changing the fps within the same project and then put their footage in a 25fps timeline with the frame sampling option (not frame blending, as this is yet another story) they would mix the footage with very different amounts of motion blur... And there is no consistency whatsoever in keeping the consistent shutter angle

[@PaulJoy]

Thanks, yes it’s always a subject that causes a lovely debate :)

[@wilcurran3377]

Nice explanation Paul, thanks this definitely helped me.

[@PaulJoy]

Cool, thanks for letting me know.

[@TheCristolShow]

Great tests and explanations here. Thank you

[@PaulJoy]

You are welcome!

[@colinthecameraguy]

That’s very interesting and relevant to me: I am often recording a local football (Soccer) team and I use 50p on the A Cam as it’s on sticks with a video head and, with all that panning, 50p is noticeably better than 25p. Most of the footage is played back at 50p with occasional bursts of (slo mo) 25p. I just carried out a quick test of me shadow boxing in the hallway and yes the 1/50 shutter speed does look better - when played back (at 50p) - than the 1/100 shutter speed however; when played back at 50% speed then the 1/100 shutter speed looks clearer and more clinical whereas the 1/50 shutter speed looks more ethereal (which doesn’t offend me) and, since I plan to play most of the footage at full speed then it makes sense to record at 360 degrees shutter angle (1/50). I shall give it a try this Sunday!

[@PaulJoy]

Sounds good, let me know how you get on. I’ve not worked on anything with a 50p playback but I can imagine it works well for sports.

[@skymakai]

Yep, depends a lot on the subject matter. High speed action where you want to have more detail, best to shoot at 180 degrees.

[@alassafcam]

Amazing how you explain it to us Thank you so much

[@chitung2277]

This addresses the issue I had shooting on 50p but with 180 deg but at normal speed playback it looked jittery. Now I get it. Many thanks.

[@PaulJoy]

Great stuff.

[@graemetowner7257]

very well explained and very interesting ...!

[@willgavillan]

Very good video, gotta give this a try

[@Timsfilms101]

Great! This is the best explanation and description. Thanks 👍 subscription definitely

[@PaulJoy]

Welcome aboard!

[@Prieget]

Great video! I thought about this recently that 360° angle could be better at 50p for a 25p timeline/delivery to go between regular speed and slow mo without that 90° angle look at regular speed but was never quite sure as I only shoot but don't edit the footage and don't know if its going to be used at normal speed or slowmo, so this video is pretty reassuring for me that 50p 360° angle footage on a 25p timeline looks at the same as 25p 180° angle footage. Great to know too that the slowed down 50p 360° angle footage doesn’t look too different than the slowed down 180° angle footage. Thanks!

[@PaulJoy]

Glad it was useful, thanks for letting me know.

[@HuFilms]

Great video Paul, I was thinking of doing this lately as it would make speed ramping and playing back higher frame rates at their normal speed and not conforming them to the timeline fps, look more natural and cinematic.

[@PaulJoy]

I've not tried it for that but in theory it should give you more detail to work with. let me know how it works.

[@adriancluskey3640]

Brilliant video 👍

[@KarinaKapri]

I KNEW there was something off about using the 180 rule with slowmo! I've been tinkering with shutter speed for weeks. Even finally bought some ND filters. This was the final piece of information I needed. Thank you!

[@PaulJoy]

If you’re only using it for slow-mo then it generally works fine, the problem start when you try to play it back in normal speed.

[@jdpainson]

Amazing video ! Thank you so much ! Video-life-changing tip !

[@PaulJoy]

Glad you enjoyed it!

[@dondouglas]

Thank you very much for the great work. Thank you !!!

[@iancraig]

Hi Paul. Really great explanation. I have used 50p at 1/50 for a long time when delivering at 50fps because for me, it has always looked more natural. (And smooth) I recently moved to 60fps to see how it looked on TV screens because some say that the TV screen scans at 60hz or 120hz and 60 is a better fit. There are two historical things in the video world that I struggle with. One is the insistence that 24/25 fps is the best frame rate to use. Whenever I use that frame rate, pans and things moving across the screen develop a judder that is pretty hard to watch on a large tv screen. No matter what shutter angle. Pans have to be painfully slow. Especially on modern, high contrast and bright TV’s which show it even more. HDR is a minefield in that respect. The other thing is this insistence on 180 degree shutter. We no longer have an ‘angle’ to think about and since the shutter speed dictates motion blur, it is quite misleading for videographers to state that 180 must be used at all times for motion blur. (Agreed that for slowing footage down, it is a good idea) but not playing back at the higher frame rate. What they often complain about is the fact that 50fps has no motion blur so they hate the look of it. In fact, it has the exact same motion blur if shot at 1/50 and is just smoother looking with less judder. Your shot of the mixer looks fantastic and I’m presuming that it was shot at 25fps. No judder on the mixer unit! I wish I knew the secret, but my 25fps footage always looks ‘historical’ to me!!

[@PaulJoy]

Thanks for the excellent comment Ian. You're right, frame-rate and motion blur experience is a very subjective thing. I'm definitely in the camp of preferring the classic 24/25p look over a more realistic and fluid 50p but theres no reason at all why everyone needs to agree what looks best. Regarding the panning judder / strobing, yes even the latest high end flat screens for Sony and LG still struggle with that, it's quite often the TV's inability to display it as shot over the inability to capture smooth footage. As you say that's one of the many things we have to consider in our shooting. Thanks again, P

[@SantiagoMonroy5]

I will always far prefer 60fps at 1/60 for most content out there, seeing 24fps content on KZbin (specially with vloggers) just look extremely jittery and choppy and it just doesnt look great.

[@iancraig]

Yes, I tend to use 50 or 60fps as well. Mainly for smoothness on TV. I’m actually not that keen on a ‘cinematic’ look in any case for family videos. Always makes me think of the 16fps projector days when we used film stock. It looked ‘cinematic’ but not realistic so for me, they look kind of ‘historic’ and way in the past, just because of the look of them. Some like the way that it takes you away from reality, but I don’t feel that it works so well with family stuff.

[@SantiagoMonroy5]

@@iancraig yeah, vlogs, gaming, wildlife, sports and practically anything that isn't "cinematic stuff" like weddings or films per say, 60fps is so much better and practical

[@dirkwachter9406]

In order to really understand the 180° shutter angle theory with all your heart, it is not enough to just watch 1 explanatory video. You have to watch a lot of videos from experts and listen to them carefully. Your video here is such a valuable contribution to a better understanding of this topic. Thanks for that and best regards from Germany! Dirk

[@PaulJoy]

You're welcome Dirk, best regards to you too.

[@tyleradams3490]

I remember years back I was watching Dexter and they would often pop into slow motion mid shot. I began to notice that every time the shutter angle looked like 90 it meant they were about to pop into slow motion.

[@PaulJoy]

Thats really interesting, thanks for the heads up.

[@tytang2010]

This is very useful and thank you for the video. For the 50P with 360 degree, it is smooth when play in 25P with 180 degree line in normal speed because of the "double counts", however, when play in half speed, there are too much motion blur, normally slow moving object would not generate that much motion blur. Of course, this is an arguable point, very subject. Don't get me wrong, it is a very useful video and I learnt a lot from your videos. Thank you!

[@PaulJoy]

Correct, the question comes down to whats more important for you, having 180° shutter angle on your regular speed footage or slow motion footage.

[@TaoCovillault]

Very interesting indeed 😊 I've been shooting a lot of aftermovies for festival lately and I think I'll adopt this 360 too. Especially because in most of what I do, this dreamy look in slowmo can actually be a plus! Thank you 🙏✨

[@JeffBourke]

But don’t tell anyone because you will upset the KZbin.

[@petermeinhart3735]

Same here! I shoot at 50p 360 bc of "lack of light" purposes and it made perfect sense to me, bc 1/50th shutterspeed is sufficient for slomo

[@TaoCovillault]

@@andrewj22 I think I see your point here and I think you are right in the case you describe. But I think in most cases, timelines and exports are set in 24 (*25) or 30p. And that changes the result because if you shoot 60p at 180°, you get this certain amount or motion blur for each picture as you said, but by exporting it in a 30p timeline, you divide the number of frames you have by 2. 30/60 frames are deleted ( or *hidden), so you end up with 30 frames that are still exposed at 1/120 But if you shoot this 60p clip at 360°, then when played on a 30p timeline you get the correct motion blur or 1/60s, and when slown down at 50%, you get an excessive motion blur BUT it is less appearing because thr movement is also slower. From my understanding, shooting 360° is a gresat tool for a very specific situation: When you shoot something without knowing if you will slow it down or not. AND most probably, you will keep it normal speed. Shooting 360 AT HIGHER FRAMRATE, give you extra frames in case you will slow it down, but gives you the correct motion blur if you don't slow it down. Very good for things that are unpredictable, like event or reportage, run and gun shooting 😁✨

[@PaulJoy]

@@TaoCovillault Thanks for your reply here. I"m afraid I have had to hide @Andrew J's comments on the channel because he has been spamming multiple comments on the video with the same reply. I welcome discussion about this topic and would love to have the discussion to try and explain where I think he had misunderstood the video but posting accusations on lots of other peoples comments is not the way to do it.

[@philsgarage64]

This morning, I was editing some landscape videos shot under very windy conditions, and despite the gimbal, the footage was a bit shaky. I was regretting to have shot at 24fps knowing that at 50 (or 60) I could have slowed it down and thus have stabilized it. I though about it and came to the same conclusion as yours … and found your video !! Perfect ! The only flaw (tell me if I’m wrong) is that every frame shot will have half of its original data. On my camera , the video bitrate is 130 Mb/s. So the more pictures I take in 1 sec, the less data they will record (as they have to share the 130 Mb) . Anyway, our cameras are so crisp that the difference is not visible ( one must have an eagle eye to see the difference between 1080p & 4k on standard footage !) . Great video indeed 👍🏼

[@PaulJoy]

That’s true although with xavc-s I wouldn’t expect it to make much difference. Xavc-I maybe, although it’s still a variable bitrate so I’m not sure. Try shooting a 30 second clip in 25p and another in 50p and compare the file sizes!

[@philsgarage64]

@@PaulJoy Hi. You're right, I did some tests this afternoon to compare 25fps/50; 50fps/50; 50/100 and even 50 fps/80 (so almost just in between 50 for motion bluer & 100 for a crisper image when moving). 80 avoided some visible blur when in slow mo but was still giving an excellent motion blur and may be a nice compromise (The test camera is a DJI Pocket 3 that I fixed on my motorcycle, so have a stable image and motion blur is quite a challenge, but the gimbal helps a lot). And when I checked the footage, average variable bitrate is between 80 Mb/s and 110 Mbs depending on the shots, so below the Max 130 of the camera. So no real loss of quality. I have to experiment still a bit, but I may go for a permanent 50fps/50 (or 80) to have an option of slowmo to stabilize in post . Thanks again. Philippe

[@orpaztron]

the is GOOD! always shooting outside in hard conditions and external light or variable ND filter isn't always the best solutions so thanks to you now I have more tool to adjust the shutter speed/ light situation.

[@PaulJoy]

I don’t use this to adjust exposure, I fix my shutter at 1/50th so you may have misunderstood the point here. Shooting at 50/50 instead of 50/100 will actually increase exposure.

[@fredo1070]

The exact answer to the question I was looking for.

[@PaulJoy]

Glad it helped, thanks for letting me know.

[@delwood77]

Dear Sir, Thank you so much for this video. A few years ago I was shooting a project for Virgin Trains. During the weeklong shoot we were traveling from London to Manchester and back and then to Leeds multiple times. I wanted to capture the view of the English countryside with the landscape in the foreground wizzing by contrasting the parallax movement of the countryside against the sky. It took the whole week of traveling to get the location right and the shooting settings. I experimented with many different shutter angles until I realized that unless I shot with a 360 degree shutter, the movement of the foreground shrubbery would strobe or stutter and be extremely choppy and distracting, --almost like a pulldown error when converting footage but worse. I've tried to explain this to multiple people but they are insistent. It is very relieving to know that I am not the only one to notice this. I will look back on my archive and see if I still have those tests and perhaps I can put up a video of the results to help fight this dogmatic falsehood!

[@PaulJoy]

Hi there. Thanks loads for sharing your experience, while many people like there to be 'rules' for camera settings there are none that are always the correct solution.

[@DLD_Photography]

[@PaulJoy]

Cool, let me know if it works for you.

[@RyanHeath87]

This answered my question I've been searching for! I've been filming a documentary type film at 60p and using it on a 30p timeline, simply for the smoothness of certain clips being played back slow motion. I noticed the normal speed playback was somewhat jittery looking and I suspected the 180 degree shutter speed being the issue.

[@PaulJoy]

Yup, thats exactly what I noticed too when I started shooting in 50p. Glad it helped Ryan.

[@danfarmer_photo]

There is a video out there that explains this in more detail. I can’t quite recall who done the video, but I think it was Caleb from DSLR Video Shooter. This is true, but not entirely. You have to remember that half the frames will be dropped. So as the image is moving from one frame to the next, half the frames are dropped to reduce it from 50 down to 25, and then the NLE will use frame blending to make sure they flow. The issue is, which frames are dropped. If you move from frame to frame, sometimes the jump from one to the next is jittery because they don’t actually follow each other because there used to be a frame in between. The information that was lost is almost unnoticeable, but sometimes enough to cause the jitters.

[@PaulJoy]

@@danfarmer_photo Thats not true for FCPX, I'm not sure about other NLE's. In FCPX there is no frame blending when halving the framerate, it simply only plays back alternate frames. This should be true whenever exactly halving the framerate however if you go from say 60p to 25p then frame blending or frame skipping would be required.

[@zantigar]

Incredibly rigorous demonstration of an extremely subtle issue about shutter speed and frame rate - and I would even go so far as to say that, because the motion blur at 1/48 sec (1/50 sec) when PLAYED BACK at 24 (or 25) fps respectively looks best (imho), ANYTHING shot at speeds faster than 50/60p should be shot at 360 degree shutter angle (in other words, anything shot at speeds equal to or faster than 50/60 fps should be exposed for the ENTIRE DURATION of frame exposure, and the 180 degree rule dropped altogether). THIS should be the new rule of thumb! Thanks so much for getting me on a train of thought which has led me to this brilliant conclusion (Q.E.D.)!

[@PaulJoy]

Thanks for the long comment and consideration. Your approach makes a lot of sense. I would say that like anything else with shooting video every shot requires consideration. Choosing a level of motion blur is like choosing a depth of field, you make the choice depending on what your producing.

[@shobhat]

This is crazy! I might try 4K@120fps at 1/125s shutter speed and test it out! It actually looks great either way (normal/slow motion) here with the 50fps at 1/50s. Amazing tip and it can get very handy for low light situations as well!

[@PaulJoy]

I often use 1/100th for 100fps when shooting for slowmo and it looks great for things like real estate videos. Let me know how you get on. One thing to bear in mind is that anything over 50/60p doesn’t work well for playing back at normal speed.

[@SantiagoMonroy5]

@@PaulJoy Not many people can even see 100/120fps since most screens are capped at 50/60hz, and even then KZbin only shows 60fps max, the thing is, you cant go any lower than 1/120 at 120fps so if you decide to use it on say, 30 or especially 24fps, it just looks jittery and unnatural if you're not slowing down so i really wouldnt recommend shooting 120fps for a 30/24fps timeline unless you're slowing it down. 60fps on 30fps timeline works since not only is it divisible, you can still use a relatively slow shutter speed (like 1/60) so it looks ok and natural, you cant do that with 120fps since its 1/120, i guess you can use it for 30fps or 60fps timeline since its not only divisible but high shutter speeds dont look too bad unlike at 24, but it would be a hassle for little reason, worse low light and most cameras wont look that good at 120fps compared to 24/30 or even 60 on some, sure you can slow it down even more but... most of the times you really only need half speed. If you're shooting something and dont know yet when and if you're slowing it down, shoot 50/60fps at 360 (1/50 1/60) and export it at 25/30fps and should look correct both normal and slow motion (of course you can also export at 50/60fps if that's your liking, 60fps at 1/60 looks way better than 1/120 when played back at normal speed and that FPS). 100/120fps (or higher for that matter) really only shoot it if you're planning to slow it down in post and avoid importing 120fps to lower fps timeline (like 24fps) at normal speed for no reason (sure it could work for 30/60fps but is it really worth it?). Or unless you want to shoot 120fps and export it at 120fps then sure, by all means and i would agree that shooting that at 1/120 should look more natural (but remember that KZbin and most social media for that matter, only shows 60fps max, so i dont think there's a good reason to export beyond 60fps, unless we were talking about Gaming then sure, more FPS the better)

30 will be smoother than 25 but which one you use should be led by what you're delivering. For filmic content I prefer 25 but if going for more true to life look and feel then 30 could help.

[@Cheekywekamedia]

What the actual heck, Paul! How is 360 degree not the standard then because it has no down side....I think? This is amazing!

[@PaulJoy]

Hey Ben. It is a slight compromise for the half speed footage as it has more motion blur than 180° shutter would produce however that compromise is a lot smaller in my opinion than playing back 25p at 1/100th which is what it would be if you shot at 50/100 and then dropped half the frames for 25p (non slowmo) playback. The thing to remember about this is that I'm talking about the ability to drop half the frames and use 50/60p footage at normal speed on a 24/25/30 timeline.

[@jamiequinlan]

Great video, confirmed a hunch I had! Tired of shooting for slow mo sticking religiously to 180 shutter rule, and then the footage just doesnt look good at normal speed. Cheers!

Great, glad it works for you too.

[@mc25141]

I totally agreed. I shot a lot of 50p videos on mirrorless camera with 1/50 for my private social media and for broadcasting work. For 1/100 the motion looks totally jitter, look too digital/like from smartphone (motion is all too sharp like there is has no motion blur), and not looking smooth, especially compare to 180° setting in Sony FX9 or Sony PDW camera. After editing session all shots from 50p with 1/50 which rendered to 1080i 25p looks similar to 180° from Broadcasting Camera. I think 180° Shutter Angle is not always a must to apply in digital era, only that we have to find the look we want and avoid the flicker from light source, that's all.

[@PaulJoy]

That was a helpful video, thanks for that. I'm going to travel next week and were in confusion if I should shoot at 1/60 or 1/120 for 60 fps. 1/120 is great but looks stuttering when slowed down. 1/60 has a bit too much motion blur. Guess I'm going to shoot somewhere between 1/60 and 1/120 for my on-the-go shoots.

[@PaulJoy]

If you're delivering at 60fps then go with 60/120.

[@drefen21]

This was very well explained I’m new to videography but I’ve been watching tons of videos, I appreciate this post, but I have a question if I record at 50fps and use the 360 rule (1/50 shutter) should I export at 50fps and it’ll still be equivalent to 25fps?

[@PaulJoy]

Hi. My reasoning for shooting 50fps at 1/50th is that I’m expecting to use the footage both for slow motion and normal speed in a 25fps project and export at 25fps. So no, shooting at 50fps at 1/50th and exporting at 50fps would still be 360 degree shutter.

[@mrdrgonzo]

I'll have to give this a try as I shoot 50p for most of the day incase there's anything I want to slow down in post, have always shot 180 but will definitely give this a go and see how it looks. Be good to have more light for the first dances too!

[@PaulJoy]

Cool, let me know how it works for you.

[@antovega2]

the problem with 360 for me at least, is that the additional motion blur you get from 60p having 1/60th makes the slowed down shoot not look as slow as if you just keep it at 180(you get that much needed detail that creates the slowed down effect).. i encourage people to be deliberate with what they are shooting and just take one second to think when you actually need a slow mo shot.

[@MaxPhotoGraphic]

Thank you Paul I've just inscribed my self to your channel, For myself I think that a 360° will be better for the interior shooting with natural light or low light I have a Sony a6600 with a 18-105 @ F4 and with 25fps @ 1/25-1/30sec i have a ISO of 200-1000; when i set 25fps @ 1/50sec the video on Full HD res is still looking ok but the iso are generally from 400 to 8000 iso. Honestly on My 15" inch PC I can rarely see the grain unless I don't want to look for it, but it seems to me that the pictures are a little more soft than when shoot under iso 1000. I have noticed that with 25fps @ 1/30sec i need less a gimbal than when I shoot 25fps @1/50sec at least in this few tries. Thanks again Max

[@PaulJoy]

Hi Max, thanks for the sub. In terms of shutter angle when shooting 25p, yes you can get away with 360 degree shutter and I do this myself sometimes but you just need to bare in mind how much movement is happening in the scene because the additional motion blur can start to look unnatural. This video was really aimed at shooting 50p for 25p delivery in which case using 360 shutter angle and dropping half the frames still results in the same amount of motion blur as shooting 25p with 180 shutter angle. Thanks again.

60fps at 1/60 is like a perfect hybrid tbh for KZbin, Slow motion still looks good and better than just 24/30fps (heck, you can say it makes stuff look like they're moving faster than they really are), and in normal speed, if exported at 60fps, it looks far more natural thanks to motion blur (against 1/120 or higher), so you're getting ultra smooth footage and still normal blur, and if anything, you can export it at 30fps and look like normal 30fps 180, just that you can always slow it down. (for PAL, replace 60 to 50, 30 to 25) Also, its better for low light since more light comes in

[@PaulJoy]

Exactly!

[@RotterStudios]

This is SO GREAT! PERFECT! Question.....what if you shoot at 60 fps, but instead of 1/60, you go 1/120, such as, if it's a really bright day. I know you could change the iso, or aperture, but just wondering. .....or 60 fps and 1/180, basically multiples of 60, or whatever fps you shoot in.

[@PaulJoy]

It’s more a question of how the finished video is being delivered. If your finishing your video at 60fps then you could in theory shoot at 120fps with a 1/120th shutter and still be able to use the footage at 60fps with equivalent to 180 degree shutter angle, ie 60fps with 1/120th shutter.

[@MikeO01]

Very informative. It puzzles me that EVERYBODY talks about, the necessity of ND filters and the 180 shutter-rule. Can’t you get as good as a motion blur in post (like Davinci Studio)? One would be more flexible and wouldn’t have the hassle with the NDs all the time. Hardly anybody talks about the negatives/restrictions of using an ND filter like, color-casting, vignetting, having to use a higher ISO sometimes, not being able to use polarizers with a variable ND filter which is usually less of a quality anyway, bad stabilizing results, etc. If the motion blur is only done in post, without NDs, how good and easy is the result of a proper motion blur and quality?

[@simonjacobsphotography]

Interesting. Very interesting...

[@PaulJoy]

I feel like there might be more to this story!

[@ChadWork1]

So basically when shooting in 60p or 120p you can just set the shutter number to match the fps. That's cool because the Sony FX3 doesn't do shutter angle, and if you're switching between 30p and 60p you don't even have to touch the shutter. Added bonus is there will be more light coming in too.

[@JamesHustler]

I've thought this for some time also. Useful video. One relevant point I'm not sure was covered was data loss. Surely stripping out the middle frame if using at 25p would result in binning half of the data rate? i.e. 200mbps 50p on a 25p timeline at 100% speed would be equivalent of about 100mbps wouldn't it?

[@PaulJoy]

That is a good point James and thankfully with the latest generation of cameras it becomes less of a problem than it used to be. Back when I was shooting with a Canon C300 shooting 50/60p meant reducing resolution to 720p at 50Mbps in only 8 bit. Thankfully the tech has moved on to the point where that becomes a non issue as the cameras are capable of increasing bitrate in line with frame-rate to maintain the data rate for each frame. The FX3 for example records up to 300 MB/s in 25p and 600 Mbps in 4K 60p.

[@lifebynico_]

Great video! At what shutter angle would you recommend for 40P on a 29.97 timeline?

[@PaulJoy]

Are you shooting 40p in order to slow it down to 29.97? If so then you could use 1/80th but why 40p? You may be better off shooting 59.94 at 1/60th that way you can slow it down to half speed or use it at normal speed.

[@karlmikovits6599]

Right, I get what you're saying and fair enough, but simply for discussion sake, this is something I would never implement, mostly because of the type of work I do. I finish all my projects in 24p. I feel it looks the best and most natural. Unless I really want to go for a specific look for a scene, I stick to the 180 rule for everything, as I feel it looks the most pleasing to watch. When filming slow mo in 60/120/240 (sticking to 180 rule) I always slow it down to 24 so it matches everything else for the look and feel. I don't mix and and match frame rates and shoot everything with an idea of what I'm going to use it for. I think it's good to shoot with intention and to be specific about your settings, your shots, scenes and the entire project. This is very much my view on filmmaking and what you say certainly works and can be helpful for specific kinds of work and video shooting. I very rarely comment on youtube so just wanted to put my two cents in. 👊

[@PaulJoy]

Thanks for your thoughts. I totally agree with you and would set per shot if I know up front how the clip will be used. Where this is useful is when shooting 50/60 not knowing which clips will be normal speed or slowmo.

[@healthtobe9543]

Thank you for this deep investigation! I am kinda getting the idea, but not fully. What to do with 120fps if I possibly can play it at a normal speed (30fps timeline)? Which shutter speed to use? Thank you in advance for the answer!

[@PaulJoy]

Hi there. The problem with 120fps is each frame can only be exposed for a maximum of 1/120th of a second so it’s impossible to get the equivalent of 180 degree shutter at 30fps which would be 1/60th of a second. The slowest shutter you can achieve is 1/120th per frame, so if you place that clip on a 30fps timeline each frame will still have 1/120th which will be equivalent to 90 degree shutter.

[@MauricioNunes92]

Absolute great explanation! I do wonder though (and once I get my camera I'll try it) about shooting at 50 fps with 1/50, and then playing that back on a 50 fps timeline. I'd assume that when compared to 25 fps with SS 1/50 in a 25 fps playback, the 50 fps one will make faster movements, such as running, look better, while still maintaining that motion blur. Thoughts?

[@PaulJoy]

If shooting for a 50 fps timeline and you wanted to use a similar method as described here then you would need to shoot at 100 fps with a 1/100th shutter. If shooting 50fps for a 50 fps timeline then you may as well shoot 1/100th unless you want more motion blur than typical 180 degree shutter.

[@PaulJoy]

It’s an interesting one because all this talk of 180 degree shutter is to emulate the look of historic film. If delivering at 50fps then your already discounting that look so it really comes down to the visual look you want.

[@3elemente]

This is a very ineresting view on this topic. How would you approach that for a 50fps Timeline? Thanx for this great video 😊🤘

[@PaulJoy]

A 50 fps timeline would require you to shoot at 50 fps for normal speed playback but if your camera is the ability to shoot 100fps then it could be used in the same way, ie shoot 100fps with a 1/100 shutter. That way for non slowed down footage half the frames would be dropped and the playback will be the same as if you’d shot 50 fps at 1/100.

[@3elemente]

@@PaulJoy Thanks for your reply, Paul! Two more questions: 1. Do you see a difference between A: 50p 1/100shutter in 50fps Timeline and B: 25fps 1/50shutter in 25fps Timeline? (I sometimes have the feeling "A" is more stuttery in terms of motion blur, would 50fps 1/50 be better?) 2. Don't you have stuttery footage, while panning for instance, with 50fps 1/50shutter in a 25fps Timeline? Thanks for your efford answering questions from the community! 😃👍

[@mOo84]

This is really helpful thanks! I shoot corporate videos and often prefer the smoothness of 50fps footage for b-roll (and option to slow down to 50% in the edit), but 25fps for interviews. Losing a stop of light when switching to 50fps/100 shutter speed was sometimes problematic so shooting 50/50 will help. Can I just check this all still applies if I edit in a 50fps timeline within Resolve?

[@PaulJoy]

I’d say it depends if your delivering at 50fps. If you are and want to stick to 180 degree shutter for delivery then no it wouldn’t, you’d then want to shoot with a 1/100 shutter to maintain the desired motion blur. You could however shoot at 100fps with 1/100 shutter if your camera is capable of that. As always try it out on something non critical first as I don’t use resolve and can’t say how well the t would work.

[@mOo84]

@@PaulJoy thanks Paul, makes sense now! I shoot and deliver in 50fps most of the time primarily because I like the ‘soap opera effect’ as mostly filming corporate events where the real look is desirable. Can still slow down 50fps on a 50fps timeline by 50% and it looks fine. 100fps at 1/100th would definitely work if I want more pronounced slow motion 👍 The motion blur effect on Resolve also does a great job at making 50fps (1/100th) footage look normal played at regular speed on a 25fps timeline.

[@photos-fera7392]

Alright I am one of the 300+ people having to comment on this incredible piece of information. I shoot real estate video and if I understand correctly I can shoot at 59.95fps (60) here in Canada and now use 1/60 shutter instead of 1/125 allowing me DOUBLE THE LIGHT COLLECTION but still with the option of slowing things down by 50-60%??? I usually edit on a 23.975fps timeline. If so this is absolutely mind blowing and changes everything for me. As a real estate videographer I either slow things down or ramp speed up all the time but the 1/60 shutter (double the light) is what blows my mind and still being able to slow down... If I shoot this way can I still use my 59.975 clips at normal (100%) speed should I need to? Sometimes I will use fast paced audio track which more or less need to be left at normal speed or even sped up (I am shooting at 59.975fps on a 23.975fpstimeline) Thank you so very much for this information! This is incredibly useful!

[@PaulJoy]

Yes you can, and yes I shoot some interior videos and you normally need all the light you can get! Best advice is to try it out somewhere like your own home and see if the level of motion blur with 1/60 shutter is acceptable to you for your slow motion shots.

[@anhtran9111]

great video, I always shoot 360 degrees when shooting at 60p because you get the motion blur and smoother footage than 24/30p. I never really understand why people were so hard pressed on 180-degree shutter rule. A better way to think of it is that 1/50th of a second is the natural motion blur we perceive in real life. We also see at a much higher frame rate than 24p in real life so it just rational that we shoot documentary with 1/50th shutter regardless of the frame rate.

[@PaulJoy]

Surely real life shutter speed depends on how quickly you can blink? ;)

[@colinjudge1261]

While it's true that approx 1/50th of a second feels like a natural amount of motion blur, that only really applies to native playback (aka, 24p on a 24p timeline, 50p on a 50p timeline, etc). Once we decide to playback in slow motion, then we're effectively breaking realism in order to allow us to watch something play out at an unnatural speed. To illustrate my point, even if it were technically possible to shoot 120p at 1/50th of a second, the resulting playback in slow motion would just look like a very slow moving blur. People tend to like to stick with the 180-degree rule, because it gives the slow motion footage that same amount of motion blur that feels natural to us at regular playback. But I agree that people tend to stick too rigidly to the 180-degree rule. There are pros and cons of each choice, and it's the job of the DP to decide what works best for the shot. It really should be called "the 180-degree shutter guideline". 😉

[@anhtran9111]

​@@colinjudge1261 you are absolutely correct, people who shoot in 60p do so because they intended the footage to be slowed down, so they must shoot in 180 degree rule. This way the slow-motion footage has the correct blur instead of being too blurry. But for me, it was always the extra frame even if it's 1/50th of a second. This makes the footage feels smoother and more real. This is what I want when I shoot documentary-style. However, it goes to show you that it's better to understand why you are doing certain things than to follow it because that's what you have been taught. cheers

@@anhtran9111 Completely agree, this is why it's so underrated to understand the fundamentals.

[@SCHAUDENLUCAS]

Awesome video. Thanks so much. I'm doing video stuff as my main income source for quite some time now, but have never seen such a great explanation about shutter speed rules. Not even remotely. There is one topic I'd love to know your opinion about: since projects are often on a tight budget and customers do want photos too, I tend to offer them screen grabs instead of hiring a separate person. To have crisp stills later on, I usually use a higher shutter speed (45° and faster) and add motion blur in post if necessary. Not sure it this is the best workflow though. If you pause the video at 6:59 you can see, that the Kitchen Aid logo is much blurrier on the right side. Do you think that happened just because the focus wasn't as good (different placement, more shallow dof...) or has it something to do with the combination of 50fps and 1/50th shutter angle? I'd rather have a bit more jittery motion, than a less crisp picture.

[@PaulJoy]

Hi there. I’ve not tried adding motion blur in post but I’ve had a few comments from people saying that works for them. Your solution sounds plausible, especially if it’s something your editing yourself and your confident in the post motion blur workflow. Personally I’d prefer to know if captured the footage with the required amount of blur in camera and shoot stills separately but if you don’t have that option and the client is happy with the results then why not, you do what works for you and your client! Logo is likely a depth of field thing I’d say.

[@SCHAUDENLUCAS]

@@PaulJoy Thanks for the reply! I will make some test footage with 360 though and check if the stills are crisp enough, because I usually record everything in 50p to be able to slow it down later. That might be more efficient than post blur. Especially with a gimbal and if there is not to much fast action going on, it should be fine.

[@elijahhoffman2966]

i like it. just considering things that get shot slow mo (sports or lets say a bug or bird in flight - might benefit from the faster shutter speed, as the motion is plenty fast enough to create motion blur) i do like this and am going to test regardless - thanks for the ups!

[@PaulJoy]

360° shutter might not be a good choice for birds in flight as there would likely be too much motion blur with all the movement. As I cover in the video the there is a compromise withe 360° shutter in that there is added motion blur but the benefit is that you can also play the footage back at normal speed and the blur will be the same as if you shot with 180° shutter. Let me know how your testing goes.

[@TokyoXtreme]

This shutter debate has come full-circle.

[@PaulJoy]

Pun intended? ;)

[@beesmith9614]

Genius!

[@philsgarage64]

To add to my previous comment and after studying my test footage : this trick of 50(60) fps 360° rule is perfect as long as your camera is stable. Let me explain: if your camera is stable, every shot will have a clear and neat image except some blur of the moving subject inside. In slow motion I agree that the blur will be quite poetic and different that with 180° rule. But now , if your camera is not stable (I did my tests with a Pocket 3 on a motorcycle. Gimbal does great job, but it’s moving anyway), some pictures at 50(60) shutter may be shaky among a flow of good ones. (At 100/120 or above, a faster shutter will avoid that); it’s not a big deal when playing normal speed. But when you slowmo it, then the big blur is quite visible. So , from my experiment : YES I will now film at 50/50 to have this option of slowmo free of mind. But if I feel that my camera (my camera not my subject) may shake, I will increase a bit my shutter to avoid blurred image while still keeping a good motion blur.

[@PaulJoy]

Thanks for sharing you're findings, I agree that if theres a lot of camera shake additional motion blur could be a problem, plus, there's always going to be subjects / styles that need additional consideration re settings.

What shutter speed should be used for native 50p/60p playback (not slowed down, and no frames dropped), a 50p/60p timeline with the final video rendered at 50/60p?

[@PaulJoy]

Video shot at 50/60 fps to be played back at that same speed would generally be shot with 1/100 or 1/120 shutter accordingly, ie 180° shutter. Of course you could shoot 100 fps at 1/100 or 120 fps at 1/120 if your camera is capable of doing so and then the method shown in this video would still apply allowing you to use some shots at 50% playback speed without compromising the shots played back at 50/60.

[@RishiRajKoul]

Would ISO and Aperture also be factors that determine shutter speed... assuming one does not have neutral density filters for very bright scene or when one would like to use lower shutter speed to use lower ISO to keep noise down

[@PaulJoy]

Yes absolutely shutter speed will effect exposure and if you don’t have any other way to reduce exposure then you can use shutter speed but at the expense of a negative effect on motion blur.

[@MariusIhlar]

7:10 Yes! Thanks! This is what I'll have to do on my A7siii to get 25 fps on PAL mode. :) Thanks!

[@robertaltman222]

I shoot any footage that I might want to slow down a bit in post at 60P - with a shutter of 1/120... If I use the footage at 'normal' speed I simply add motion blur (I use Resolve) to recreate the 1/50th shutter 'feel'. It is much easier to add blur (essentially degrading the image) than try to recreate missing unknown detail/sharpness if you try to go the other way!

[@PaulJoy]

I've not spent much time in resolve but that sounds like a useful feature. I'd imagine the problem with that though is that if you end up using only 10% of the footage as slowmo then you'll need to apply a motion blur filter on 90% of your shots which I'd imagine takes quite a bit of processing power. Without trying it it's hard to know how accurate that blur is compared to natural motion blur but thanks for the comment, I'll check it out.

[@MichaelBouhnikProductions]

Amazing video, what about 100fps for a 25p timeline?

[@PaulJoy]

That wouldn't work in the same way because you can't shoot 100fps and maintain a 1/50th shutter as each frame is only exposed for 1/100th of a second. So for 25p playback with 180° shutter the max fps you can shoot is 50 fps.

@@patrickfalls6819 It's certainly a very confusing subject :) If shooting at 50p for playback at half speed then 1/100 would be typical, it's when it's played back at normal speed by dropping half the frames that 1/100 would not be 180° shutter as then the final result would be 25p at 1/100th or 90° shutter.

[@helidronesurveys4551]

Hi Paul very interesting topic - Open any (video) camera or remove the lens, where's the shutter?! Answer there is no shutter - its a way the manufacturers wanted camera operators to understand how light entering and hitting the sensor was conforming to existing rules (harking back to film cameras). So what we think is a shutter on our video cameras is actually a sampling rate - sample more often (progressive scan) and you get less light hitting the sensor - how much motion blur do you want?

[@PaulJoy]

Yes you don’t often see spinning disks in modern cameras :) I think it makes sense to keep the descriptive terms the same though. Personally I’m not bothered about having the exposure timing listed as shutter angle although a lot of people think it’s a vital part of a “cinema camera”. As you say, once you understand it’s all doing the same thing it really doesn’t matter what it’s called. It’s a bit crazy having such a thing as a 360 degree shutter angle as it’s really just no shutter at all and would have been impossible with a film camera.

related question: I shoot 50p because in the sports hall where I am capturing, whatever lighting they are using (its probably LED, operating at 50Hz - not that it SHOULD make a difference but it seems to, because its not fluorescent light but the LED could be direct AC driven), the footage seems to flicker badly at 25p but not if set for 50p for 50Hz. What's your take on this situation, Paul?

[@PaulJoy]

Yeah, LED lighting can be a total mystery and doesn't always follow the mains frequency precisely. Unfortunately with the FX3 we don't get the ability to make small adjustments to shutter speed. My guess is that it's just off 50hz meaning that when you shoot 25p the effected frames are more apparent because they are visible for twice as long. Shooting 360° shutter at 50 1/50th could definitely help. I could be totally wrong though, LED's are a total frustration , especially when you get different ones in the shot at the same time!

this makes a lot of sense because the default shutter speed for S&Q mode is 360 degree shutter.

I’m not sure if that’s always the case but interesting point!
