[@Nolroa]

​​​@@nickfifteen No. It was the part at 8:21 where captain said that a digital camera takes many shutters per second And then he cited the example of setting up cameras to make the famous “Bullet Time” scene in The Matrix (1999). The error was that indicated in that way it did not talk about the shutter speed but rather about the frame rate and to cite the example of placing hundreds of cameras in a configuration where said cameras took one image at a time to give a sensation of three-dimensional movement had nothing to do with the shutter or shutter speed issue.

[@randymations5555]

For anyone wondering, the section from 8:04 - 8:33 was entirely replaced. Not a copyright issue, the information provided is actually different. I didn't really understand the explanation the first time around, but the claim was something about how physical shutters can't cause the rolling shutter effect. The section also started out "thats how I know you haven't been paying attention." I was, indeed, paying attention.

[@kisaragi-hiu]

Thanks for pointing us to the new section! IMO the new explanation is much better: the old one asserted that the mechanical shutter is exposing to the same frame but CMOS is staggered, which doesn't actually make sense, and I instead relied on information from later parts of the video to learn what the new version says.

[@JoshuaPack]

Oh yes. I thought the way he said before like 1/300 per line was a weird way to explain it. This way is much better!

[@technoman9000]

Sounds like you weren't paying attention.

[@J0s34n70n10]

Yeah! I also love how it fits with that phrase he had, I'm like, "Ha! I was paying attention!"

[@notsam2270]

the original inaccurate explanation detailed something about how the mechanical cameras would be able to capture a whole frame with one shutter (if i recall), while the chips were sort of like a whole bunch of cameras stacked on top of each other, firing at different speeds which was said to be the reason for rolling stutter

[@MrGuru666999]

What was his question?

[@AltiumYT]

The only difference I’ve found in this version is at 8:04, for those wondering Addendum: (In the original he focuses on the staggered delay of the CMOS due to the moving of data while this version more clearly explains the mechanical’s skew (still present). Good on Captain D for always making sure these videos are accurate!)

[@Bletotum]

Nice, this does actually address an irritation I had with the original video not sufficiently admitting that mechanical shutter does have the same warp (to a much lesser extent)

[@sondrehyland3818]

Yes, someone commented to you "what..." and I started writing a comment before it got deleted... the explanation for the skew : It is just way more clearer. No "real" difference as what I remember to be odd, but not incorrect, is not properly explained. at 8:25 I do not remember any justification for why there is a difference; now there is a full explanation for 'why' - way faster (checks out)

[@johnnyz86]

​ @deadnotsleeping The original explained it as each row of pixels being like a slightly delayed set of cameras but didn't really emphasize the overall speed difference compared to mechanical, though it did mention it in one sentence. We did lose the callout to old school slow motion capture though

[@DrywallJackson]

this one feels nicer because i remember in the original version at 8:04, the captain says something along the lines of “you’ve clearly not been paying attention!” and it hurt my feewings because i was doing my best captain 🥺

eyy its my favourite cgi animator, and music creator! Love your work dude, so many laughs. your channel and voice acting is amazing

[@evil-wombat]

I build camera systems (yes, with a rolling shutter sensor) and this video is absolutely spot-on. Readout time in a CMOS sensor is a big deal, but you can't always minimize it due to the digital interface on the sensor not being able to push out bits fast enough, the camera processor not being able to read them in fast enough, or due to link constraints (signal integrity problems associated with "long" cable runs in some applications; story of my life right now). In many cases, rolling shutter artifacts (or camera motion artifacts) are corrected via electronic stabilization. The camera will have a gyroscope rigidly mounted to the lens/sensor, which records the exact motion of the lens while the sensor is capturing a frame. After the frame is read in (but before it is compressed), the camera processor will use the gyro data to move every row of the image in the correspondingly opposite direction, to line them back up again. This works for both camera shake and for the rolling-shutter artifacts associated with high-speed camera vibration (the dreaded "jello" effect), but it requires very precise synchronization between the frame read-out and the gyro data. Unfortunately, this technique only works for correcting rotational motion of the *camera* - if the subject is moving, there is nothing you can do. This also requires somewhat cropping the image, to give yourself enough "play" to perform the correction, and it creates additional processing overhead (more battery usage, more heat, etc). Still, this technique can work very well, if competently implemented. Your phone and goproes will generally do this. The computational overhead is usually mitigated by the camera processor having some form of hardware acceleration for doing the crop/warp operation. Although global shutter sensors exist, you can't easily get them in high enough resolution (at least in consumer/mobile applications) to use as a main camera. Computer vision people absolutely love em though, because you know that every pixel represents exactly the same moment in time. This makes it easy to correlate data from successive frames, for tracking/motion estimation. You'll typically find global-shutter cameras in robotics and as tracking cameras in VR headsets, for this reason. One downside of global shutter is not being able to expose *any* pixel on the sensor, while any readout is taking place. I guess that's the _point_, but it limits your maximum exposure duration to exclude the readout time (which, for a large frame, can be substantial). This, in turn, will reduce your low-light performance. I've seen 8k sensors where readout takes almost 1/30s to complete, which would leave very little time for actual exposure, if this were a global-shutter sensor running at 30FPS. You'd have to increase your ISO to compensate, which would increase your noise. Your video mentions an 8k global-shutter camera with a 3ms readout - this is very impressive and probably has a crazy data link to the sensor. For comparison, the camera in most modern phones would need closer to 30ms (10x that) for an 8k readout. A DSLR, by the way, wouldn't care about the readout - you start exposing all the pixels, let the mechanical shutter start and (effectively) stop the exposure, then take your sweet time pulling data off the sensor because the pixels aren't going to be accumulating any more light. Mirrorless and motion cameras, on the other hand, are another story. One fun fact about these CMOS sensors is that the exposure duration is actually programmed in LINES, not seconds. Basically, the sensor can "un-reset" a line of pixels any time it wants (this will begin exposure of those pixels) and the exposure will continue until that line is read out (there's no way to "pause" exposure of a line once exposure has begun). When you program the exposure duration into the sensor, you're actually telling the sensor how far "ahead" of the currently-read-out line to begin exposure of the next set of pixels. That is, if you program an exposure duration of 40 lines, the sensor will begin exposing line 50 as soon as it begins reading out line 10. The readout is actually driven by the sensor (not by the camera processor) and occurs on a known/fixed cadence; the software just has to take the desired shutter speed and convert into a line count before passing this to the sensor. At least, this is how it works for MIPI cameras in consumer electronics.

[@0LoneTech]

If you're not terribly worried about noise (hello cooled sensor astrophoto friends), with BSI sensors there seems very little reason not to add pipelining to allow continuous readout during exposure. The global end of exposure time would transfer measurements to sample and hold circuits which are scanned during the next exposure. I believe that's what CD alluded to with those extra capacitors shown in this video.

[@evil-wombat]

@@0LoneTech yeah, sample and hold would certainly do it. Reset all the pixels, let them expose, transfer all charge to the capacitors, begin the next exposure. Meanwhile, take your sweet time doing A/D and readout on the previous exposure that's being held. It would make for a more complicated pixel, but it would work. And your shutter "down time" would only need to be long enough to perform the sample/hold/reset, not the conversion or readout.

[@luppano]

Thank you for the in-depth dive!

[@xpehkto]

So, can you put a low resolution global shutter sensor alongside main high resolution rolling shutter sensor, and use movement and geometry captured by global shutter sensor to unwarp an image captured by the rolling shutter sensor?

sir I am asking that in cameras we have rolling shutter as frame does not captured at same time but different moment of time and speed at which frame become in rolling shutter is called read out speed which is normally 20ms . so I am asking if we have shutter speed 1/16sec or 60ms .then frame has information bw 0 to 20ms or 0 to 60ms

They certainly do for still photos. For fast shutter speeds, it's a slit scan that takes longer to do than the actual exposure time. It twists propellers etc.

[@0LoneTech]

The extreme of this is line scan cameras, used e.g. in industrial systems and race finish line photos. You get pictures where anything static is smeared across the entire frame (which could be extremely long) and moving subjects are captured only as they cross the line - more distorted the slower they did so.

Absolutely love the "24fps is the best", with MKBHD on screen

[@thoperSought]

I was wondering about this-I know _of_ MKBHD, but I don't know what this is about

[@skyplayx3558]

​@@thoperSought MKBHD hates 24FPS and 60FPS, and believes that 30FPS is the best

[@thoperSought]

@@skyplayx3558 thanks!

[@patemathic]

And Slow Mo Guys as they shoot in 25 or 50 fps and of course the thousands of fps slow mo

[@chicken_punk_pie]

Thanks, I was wondering too​@@skyplayx3558

[@mike_lambert]

The first explanation of “Shutter Angle” that I’ve actually understood. Thank you Captain! 👍👏

[@jaystaf4004]

I'm not optimistic you'll actually see this, but CD...your videos are so great, really some of the best stuff on youtube. Educational and entertaining, you have a great style of captivating the audience while also teaching them something. Wish I had one tenth your creativity and skill while making lectures for class. I'm so glad you do what you do, just wanted you to know.

[@fallen_cookie]

Two uploads in one day?!!? Thank you so much, captain!!

[@onyxa3144]

these videos are honestly so informative and high quality it feels like it should cost $20 for each CD style video like this

[@JiagerWufwood]

That's what the super chat is for, the heart-shaped donate button.

[@SaItogaming202]

and each $20 video would be sold as a physical cd

[@JiagerWufwood]

@SaItogaming202 LOL, Captain D made a bunch of 📀 dvds. Hi rez versions of his early videos because old YT had a res cap. I bet you could buy one!

[@emptyjay488]

Love the video, not enough dogs!

[@natehedgeman]

That ending is low-key Legendary and I'm upset that more people aren't point out how good it is.

[@PeppermintFren]

D you’re perfectionism is as inconsequential as it is absolutely mind blowing. I’m not gonna tell you to break yourself to make internet educational funnies, but it’s stuff like this that makes you so unique on the platform

[@kyay10]

Great video, not enough dogs!

[@JoltorbDoesGames]

Great new idea for a video, CD!

Halo

​@@billyboi456 yes he is

[@Topcatyo.]

The amount of work that went into this video is why Captain Disillusion is one of the best. The density of visuals on each shot is mind-boggling, as somebody who has been doing a lot of video editing for the last two years. That's not even getting into the detail put into the audio. My brother and I watched this video together (I don't think he's seen this channel before) and he came away super impressed with the whole thing

[@SuodesTzeos]

And again, 1:18 what a great but subtle reference, the voice is spot on!

[@pigeon5312]

whats the reference?

[@drojf]

​@@pigeon5312 The channel "Real Engineering" I think, complete with the blueprint style diagrams

[@therealdeemz_]

Watching all these topics be laid out and having myself understand every bit of it was the most rewarding feeling I could ever have as a photographer. The topics being laid out here are CLEARLY things that the writes understand and are PASSIONATE about. You don't see this in any other channel. Thank you, Captain Disillusion! It's also some very nice trivia to know that you're using a BMP4K ;)

[@Ben_19M]

"there is no such thing as infinity in the physical world" is my favorite phrase ever probably

[@outervale]

This is such a classic thing for Alan to stuff up. This is why he's still an intern.

[@djcjfxyz5351]

Huge Respect to you captain for re-uploading, not sure which part was changed (Perhaps that means I didn't pay attention enough) but I'm glad you always side with providing accurate information in such a fun and creative format. A re-upload gives me an excuse to re watch again and retain the information better I suppose, ahaha Your initial upload definitely incuredged me to look more into retro technology so that's always a win, keep up making the passion to learn new things exciting, Thank you Captain!

[@BetaDude40]

It's funny you said "I didn't pay attention enough" because that was one of the changes lol. It seems the only major changes were from 8:04 to 8:30 -- He completely changed the explanation of how mechanical shutter versus CMOS works and why there is less rolling shutter effect. Previously he tried to explain it as a bunch of cameras all stacked vertically on top of each other and synchronized to snap at the same time, which didn't really make sense because that analogy can also be applied to mechanical shutter. The new explanation is more concise and is just that mechanical shutter is generally much faster than the electronic readout. -- He removed the part at the beginning where he sarcastically says "This is how I know you're not paying attention," which I assume came off a little too asshole-y, even for the cynical character that he plays in his videos

[@djcjfxyz5351]

@BetaDude40 I was hoping someone would notice my use of that line, ehehe I thought it was funny the first time I watched it since I have a visual memory, but if I'm not paying attention and there's lack of a memory it's a good indication I drifted off somewhere, ahaha Now that you point out the differences, the new explanation does indeed make more sense. I remember vaguely thinking it sounded too similar of an example initially. Thanks for pointing that out.

[@dougdingle8198]

Retired video controller and system engineer here. I loved this. Thanks for taking the time and spending the money to educate the kids and some of the older dinosaurs. Also, great hair!

[@oneveryfishyboi331]

I’m so glad you uploaded this a second time, now I can watch it again and try and see if there are any differences

[@potatobutter141]

Even better the second time

[@julienbejul]

The MKBHD "cameo" had me on the floor, you're majestic!

[@scottvogel8477]

The fact that you care so much about properly informing is why your such an amazing content creator. Stay awesome captain.

[@LoveDoctorNL]

I’m already looking forward to tomorrows re-upload again 😊 Love your work CD

[@pavellishin2972]

Love this video, not enough dogs!

[@jpark6491]

[@PeterHedman101]

Your commitment to the educational integrity of your videos is wonderful! Great video!

[@AP-fu3gg]

Beautiful.

[@Blutzen]

I really appreciate the way your educational content is both incredibly thorough and incredibly fun. Thanks, Captain D!

[@VarunGupta3009]

O Captain! My Captain! Your dedication to accuracy and the truth is invaluable. Thank you yet again for gracing us with your presence this year. We are grateful to have you.

[@zachattack963]

Love this video! Not enough dogs

[@Superabound2]

It's always a good day when a new CD video drops

[@josh8560]

Two videos in the same week? The dedication is unstopable!

[@iammrbeat]

Oh my. You're more of a perfectionist than I am.

[@BernhardBB8]

Nice video! Not enought Dogs!

[@BlackWolf42-]

Looks like the end part where "global shutter" was talked about got revised in the new video. I can't remember any other changes tbh. Your dedication to the craft leaves us in awe, Captain!

[@bosstowndynamics5488]

The main change was the description of how CMOS sensors scan differently to mechanical shutters - the new explanation is much tighter, clearer and more precise. Any changes to the global shutter explanation probably follow on from that change

[@tylerkennedy4203]

im convinced you are the best teacher of our time the amount of work put into these videos and how easy it makes it to digest is simply impressive lol
