[@mussleking]

Yeah learning about Log means a LUT

[@itsmeannie_]

It's really straightforward to understand what you were conveying. By presenting different kinds of profiles and making comparisons, you help us get a thorough understanding of slog. Beautiful job!!💯💕

[@HarvVideoAudioStuff]

Glad it was helpful!

[@richardperlin8958]

This was a very understandable explanation of a term that people often use, but never explain.

[@jasonlorphotofilms]

So basically Logs are like Raw photos. Both retain a lot of information from the video and photos to where you can bring back most of what the original lighting and colors. That or do more with them during post.

[@gianninacadenas2808]

This was also my way of thinking about it, until I found out you can also shoot video in RAW. Each frame is a RAW file, so video file sizes get HUGE. Shooting log is sort of an in-between jpeg and RAW. At least that is how it was explained to me.

[@22DINGOS]

Thank you. It took me a long time to find a video defining and describing these acronyms. Please more for beginners

[@HarvVideoAudioStuff]

Many thanks! More to come 👍🏻

[@sj5dj7]

Excellent video! I have already purchased the Phantom Arri LUTs with your code and they are amazing! In post I have very little to change. It is only recently that I leant how to expose correctly in S-Log2 using histogram and zebras which makes all the difference. Shooting outdoors I also use a Hoya ND8 filter which again helps if in bright sunlight. Keep up the good work and looking forward to your low light video.

[@rugosotv]

[@amberleaf7]

And now you really wish you waited till a7iii S

[@calvinatdrifterstudio8438]

I think i can simplify this: log is useful whenever the internal camera picture profiles aren't working for you or your style. If you have the option to create a custom profile and use that, it's better. Log is a last resort suitable for people with a good amount of experience with messing with luma curves

[@BeanDar]

3:15 you look like Tony Stark in the right two images... lol thank you for the simple and short explanation!

[@HarvVideoAudioStuff]

Ha ha I'll take that :) could be much worse!

[@PatrickWithCamera]

Perfectly explained, brilliantly pictured, thanks a lot :)

[@dbchronicles1]

Side by side there is an obvious difference. I prefer the log, more detailed, more cinematic! This will change my videos and image quality! Thank you

[@wasanarif3260]

Thanks for the info - I didn’t know what the log is . But what the the difference among all types of logs mentioned.

[@eceera]

Could you please make LUTS for premiere?

[@SuchetB]

Very early on in my film career I simply used to just adjust the contrast, and sharpness by lowering them and save the setting to use again, it gives you the same effect as an official log format which does the same thing.

[@davidmackey3046]

Nicely done! Even though I'm a Canon guy, you were generic enough for any shooter to grasp the inherent flexibility of log.

[@iamsyafiqnoor360]

now everything makes sense now. thanks!

[@RecordingBlog]

Yet another awesome video by Harv the man. Thanks a lot :-) Do you have to deal with your white balance when using luts and how about the light temperature of artificial light?

[@Noealz]

it can get a little confusing but glad you lay it down

[@laika25]

What's an external recorder? Thanks, thanks, thanks

[@thejaebeing]

What is a lookup table?

[@SainRaj]

clearly explaint.. thanks bro...

[@alinachlebecek6757]

super good explanation, than you so much!! :)

[@Danimally]

The best way to use log is to change your color space from log to, lets say, rec 709 o wathever is your color space. LUTs are destructive if you can't use it properly, but changing your color space directly means that you can really tweak everything without fear.

[@CSMoviePhoto]

No, that is not how it works :) Also this video tell a different story

[@Danimally]

@@CSMoviePhoto i literally do it every single day, cause log has a non linear color space that need to be transformed to linear color space. You can edit log without a color space transform, but it will be way harder.

[@CSMoviePhoto]

@@Danimally You can't use log with Rec709. LUT are not destructive in any way. You simply can't change color space from a low color space to a large one in post so you can't use a low color space with a log. LUT affect not only the dynamic light curve but colors too. It is not a simply way or explanation on gamma and LUT.

[@Danimally]

@@CSMoviePhoto go yo davinci and try. LUTs are destructive if you cant use them properly, if you use them right there's no problem. You can certainly use a LOG file with Rec709 if you transform the color space (that's what ACES workflow roughly do). I'm just using Rec709 as an example of color space, not of the best(tm) color space. Point is that a logarithmic curve file will look awful over a EDL with a linear output, and will need a lot of color grading work... or you can just simply transform the color space from your log file to your output color space and work from there

[@CSMoviePhoto]

@@Danimally you simply don't get to right point. Here is from Sony, and is under a DaVinci Resolve pic: "Shoot in a wide colour gamut Normal video footage is shot in the REC.709 colour gamut, but material recorded in S-Log is recorded in the much wider S-Gamut colour space. Put simply, the wider the colour gamut, the more colour information can be recorded and the more vibrant and realistic your images will look.More information, more control S-Log captures far more information than standard REC.709 footage can record, giving you more control over the finished image in post-production. Instead of exposing for highlights or shadows when shooting, you can capture all of this information and choose how you want to display it later."

[@KarelZweefvlieger]

Sony log cine ie or 100 iso on a bright day outside???

[@visiontalkiesshorts]

Thanks for the information specially, about luts.. Big thanks👏

[@AngelTravelsEarth]

thank you for your clear explanation

[@thomashemler165]

Does LOG use a lot more storage due to the amount of picture information it stores?

[@HarvVideoAudioStuff]

Nope, it’s exactly the same 👍🏻

[@NedouxSews]

Very helpful info. Thank you!

[@Richard-kl9bb]

Thanks Harv

[@Tyrell_Corp2019]

Help! As a noobie here, I'm trying to find out if LOG is an industry standard setting across all video makers or... is it different for each company? AND... it seems LOG is basically a 'pre-set' similar to an EQ as in music production? (I have more of an audio background.). Thanks in advance!

[@sclogse1]

I'm a little late... worked in film and retouching for a long time. Worked as a color lab printer for 15 years, printing all kinds of commercial work. The problem with that is I still dream about working in the lab with those four Chromega enlargers, and those beaten down easels that should have all been dumped. Made a short noir when the 5D Mark II came out, shot some cool Robbin Ford, Pat Martino and Dave Liebman footage, all on youtube, and no matter what you can say about tech, it's about waking up with an idea in your head. If you go back to the late 1920's early 1930's, they already had figured out how to combine film stock, lenses, filters, (those now impossible to find rare gauze filters made from french women's stockings) and lighting to make us notice what they wanted us to notice, and do it perfectly. We watched the eyes. We didn't find ourselves staring at some odd little bump or defect, wondering well, if Carol Lombard had that and got away with it....when digital first pretended to be worthy, everything was in focus. That's fine for an R.E.I. ski video, but not for telling a story. Your eye was not directed. I figured out a way to shoot a night scene using only available street light. I shot a plate of the scene, and layered that over the film, except for the actor's area. It eliminated 90% of the noise in the shadows. Here's my short noir, Bum Rap, on the imdb web site. These imdb films seem to take about 4 seconds to start. www.imdb.com/video/vi976727833

[@ZooDinghy]

Interesting. I always wondered why my footage looks so "muddy" (for a lack of a better term). It must be the lovely rolloff. I'll have to do some tests but in high key scenarios, that rolloff on a white background may look bad.

What is the difference between s-log and j-log?

[@end27]

why does standard look so blurry at 5:36 while log is much more clear and sharp? u said log is for colors shadows/highlights, not sharpening so now i dont understand it.. i feel like while u were editing log colors u also sharpened it...

[@HarvVideoAudioStuff]

I never add sharpening to video footage, and what would be the point of doing it here 🤷🏻‍♂️

[@end27]

@@HarvVideoAudioStuff so what is it then, is left one out of focus slightly? or v-log actually makes video sharper? i mean if it does then its actually worth unlocking. shadows/highlights wasnt really good enough reason for me but that sharper video is deal maker

[@HarvVideoAudioStuff]

I wish I could tell you but it was ages ago, I wouldn’t have changed the focal point between switching modes…not intentionally anyway 😂 from my experience there’s no real difference in detail/sharpness between rec709 and log so just pick based on your dynamic range requirements and colour preferences 👍🏻

Harv, did you shoot this internally or externally? If internally, I think you should do another test using the workaround to get the true log curve in camera.

Do log footage take up more space in the memory cards?

[@kaldenlabhutia25]

[@TheGoldenMan99]

Can the camera autocorrect the recorded log footage? So I dont have to do any editing?

[@jonatasnas]

That's literally the point of using Log, editing yourself. You can use the standard camera modes to get autocorrect!

[@chatreesaleewong6398]

Log is Pores are the same?

[@HarvVideoAudioStuff]

Not the same, log is a gamma (contrast) curve and prores is a ‘wrapper’ for the file, similar to xavc etc. So you could have a prores video file which was filmed in LOG. Hopefully that makes sense, I tried 😅

[@DanielSymphonies]

i am desperately trying to understand log so forgive me if i come off as a bit of a devil's advocate; but in the first example, you said you exposed log to be somewhere in between, but you never did that standard profile, so the fact that you got somewhat better results with log there couldn't it simply be because you set the exposure to midway, and you could have achieved the exact same result with standard?
