Not really, he'd look green if that was the only step taken. He did let us know it existed and teach how it worked, but not teach exactly what he did, that would distract from the video and slow his transitions down.
As a graphic designer, would you have time to tell me whether the type of panel used (TN,VA, IPS and all sorts of LED) or perhaps the brightness output or anything else makes a difference here. Or is it solely dependant on the display being 8bit or 10bit and higher?

Having worked with digital video as a hobby since the Video Toaster's introduction, I've understood this phenomenon for ages. Your explanation - with animations - taught me a few things I hadn't given much thought to. It also explains banding better than I could ever hope to. Brilliant video as always. Keep up the great work!
You got something pre 2005 running there? Cause anything with a Core 2 Duo or equivalent AMD should be able to at least play back 480p, even on an integrated GPU
@hgfd I really liked the part where Tom was being represented by a grid of ones and zeros, which kept changing colour, value and size. I have no idea how to even start animating something like that, so it's incredible to have such high quality content available on RUclips for free.
As a digital illustrator who has to combat color banding on digital art programs, thank you! I never knew this was a thing until you mentioned it, and it immediately clicked as the reason why my gradients always look a little...unblended.
And I see it constantly in anything that has a gradient like that in other productions too! I would say it's a lot more pronounced in dark scenes, but I notice it every time nonetheless...
Compression adds some of that but another thing that might be an issue is your monitor settings. There's usually all the scenery, game, normal and whatnot modes that mess with the video. On top of that your contrast setting will also affect it but a bit less unless it's near the minimun or maximum value. These two are easy to get rid of using a colour wheel/picker where the colours blend with each other and a smooth + incremental black to white gradients. You should choose a colour mode where the colour wheel looks smooth all over and set the contrast so that dark greys or light greys don't mix with each other or turn completely black or white.
The worst for the compression : rain during the night. Multiple small moving objects, dark background and the sound is very hard to compress while conserving a realistic rain noise.
Well, you can separate the audio and the video sequences, compress the video only and then merge them back together. However, compressing the video properly is very hard because it's dark, it's moving and it has to be depicted with high quality.
The music video for Weval - Someday gets completely ruined on RUclips because of that. Páraic Mc Gloughlin edited thousands of pictures into 4 minutes and RUclips can't handle the quick switches.
Is it possible that people using mobile devices don't see the colour bands? I gather they're in the majority now, though I still find it baffling that anyone wants to consume YT on a phone (but I do realise I'm just an old fart).
@@macronencer Hehe, you said fart! Oh and it also depends on your screen. I guess for most people with average screens the banding on the brighter parts will be much less visible though. And it is *less* noticable than for the dark parts.

that's really interesting, kind of similar to how VHS would make the dark look like something was maybe going on in it, because of the reduced signal to noise ratio in the dark (same noise, weaker signal, I guess?)
The reason I love good 4k restorations is because I hardly see these. Even back in the 2000s I noticed those brands in my blu rays on 1080p TVs. If you haven’t seen The Godfather, for instance, in 4K I highly recommend it. It’s never been more dark, shadowy and crisp since the theater.

I just remember my parents changing the brightness level mode on the TV so many times. *my mum pausing movie in very intense bit* "oh my GOD IT'S SO DARK"
This is why, when I know it's going to be a dark movie/TV show, I get it on 4k bluray instead of streaming it. It's still not perfect and it depends on the quality of the transfer, but for the most part, it looks way better.
@@TrveIrrlicht Oh Yess I remember this I was watching the whole season on my Phone so small screen plus extreme darkness = not very enjoyable even tho I was still hyped af before finding out the dissapointing end of it all....
@@AluminumHaste Once you watch 4k blu rays on a good HDR display there's no going back. Maybe one day streaming services will have better compression and higher bitrate instead of using a video codec from 2003.
It's not a blocky mess in the cinema. Instead of 8 bits per channel, you get 10 at a minimum, with the option to support up to 16, and the bitrates are upwards of 250 Mbps, so you have a much greater raw colour space and little need for compression. In fact, DCI compliant cinema compression is very efficient, but lossless. Monster movie directors don't care how it'll look on TV.
Sometimes not noticing the background is the point. You need to make it look good enough that people don't get distracted by it, or don't even notice that they're noticing it. That takes skill on its own.
(btw, I know you are being funny) But with design, that's the point. If you don't notice it, then the hard work paid off. If you do notice and it isn't right, then a lot of work for nothing. Things in the background probably get the most work than the things in the foreground. Most things in film and design, if you don't notice it, that means they did their job. If there is an error in your login screen for RUclips, you'll notice. But if everything is working well, you won't notice it.
And then there are the potato recordings used for 99% of ghost captures, which are then compressed to 140p, and ripped off each time crushing the quality until you are left with grey mushy soup.
@Luc Bloom Depends. Strictly speaking the process of dithering trades resolution for more apparent colour. This isn't so obvious at high resolutions, but if you look at a dithering pattern as you would've seen it on very old computers you do lose effective resolution using dithering techniques. There's no free lunch here...
The nice thing about HD physical media like Blu-ray, is that it plays the video at a very high bitrate allowing for those dark scenes to actually look like it was intended.
There should be an option for those with super-fast internet to stream in the same quality as Blu-Ray, with a super high Bitrate. It's sad but Blu-Ray is still the only way to watch movies in the best possible quality :(
@@danielbaugh2170 the streaming servers have to process that. It consumes CPU cycles, internet bandwidth and memory. It also saturates the network for ISPs. They are not going to give you that option. We are still far from Blu-ray quality streaming.
That's why Blurays are still superior to even "HD" streaming services. A lot of people don't know about or underestimate the effect of bitrate compression artifacts. I always notice it, especially here on RUclips. The bitrate limit for a 1080p video here is painfully low.
Thanks for this easy-to-digest explanation of this phenomena. I deal with this kind of noise constantly in videos, and the inclusion of scanlines in those areas on top of the lower-bitrate they typically receive on top of the re-encoding by youtube to an already-compressed video, can make for some really weird visual anomalies that hopefully our codecs and hardware can get better at dealing with in the future.
Just like Marketing department of display manufactures show you different types of technology used in the monitor. They show you a difference between an HDR and a non HDR monitor in a picture, or 60Hz vs 144Hz picture and other stuff :D It's just generic noise on the website in that moment.
because the teacher explained it in a way more detailed fashion, didn't have time to plan a script for the lesson for months, and also because you already knew about it that Tom's explanation was more simpler to you
@@ananttiwari1337 No, they didn't have months to plan a lesson. They've had the entire time that they've been teaching to come up with a lesson. The detail part could be true, but there's not much more to it than the compression engines tend to compress darkness at a noticeable level. The video described what the compressor did as well, and in a way that's universally understandable for most people since it explains all you need to know. Sometimes teachers aren't efficient at what they do but it's okay, there are a lot of things that teachers teach and explain that most 6-10 minute videos will never cover, this just isn't one of them.
@@Saneec (Assuming we're talking about school teachers and not university professors and also basing what I'm saying on school in my country which might be completely different from others) I think part of the reason why the teacher took much longer than Tom to explain is that the teacher didn't have fancy animations that show what they're explaining, and everyone in the class needs to understand so of course if someone wasn't listening or if someone couldn't understand the teacher would need to explain it all again. Also obviously a teacher can't be expected to spend a month to work on a script to explain something (to sometimes as much as 30 people) and in such a short time for every single thing they need to explain
@@Mat-8071 Teachers are teaching the whole ass theory & case-to-case scenarios in case someone wants to make a living out of this. Stop comparing school with your YT recommendations (btw Tom
I legitimately was wondering about this the other day. As someone who studied film/post production, I knew about 90% of the answer but just hearing it from you makes it a lot clearer and visually justifiable.
I agree. I already knew about this but when explaining it to my uneducated parents, they seem to think I'm imagining things. Hopefully this video will clear it out to them.
Tom, I know you had your reservations about people helping, but your work has been great lately. I think this lets you focus on doing your part to make the videos great, and they come out even better. I'm very happy for you and excited to see what happens next!
Thank you perfectly explained! I always wondered why my videos looked relativ good on my hdr monitor but when uploading on youtube the darker scenes are always are terrible blocky mess, now I know why.
I've watched this video a few times.. and and I must say, this was SO well done with the visuals actually showing everything you need. This can just as well be a teaching tutorial in how to use visual aid to enhance the learning of a concept.
I second that. But Tom also hired a professional animation designer, it was certainly worth it. I have done something similar (with less flashy animations though)about the various image formats a long time ago. For who's interested in this, it's really fun to work with and to watch content about it.
Is this going to be one of those videos where Tom flexes his editing skills for 6 minutes straight while I'm crying working out transitions on windows movie maker?
@@Lollllllz no that's a myth, I remember years ago when I knew how to do things movie maker better than vegas, premiere and after effects that I was teaching myself how to use so decided to use it to make a super simple project on it thinking it'd be easy but the amount of crashes after just importing large files to it made me switch forever. Vegas crashed a lot too back then but in comparison is world better.
At around 3:30 when you showed the little bit with the brightness increased, that image really delighted me, it was so perfect and clean in its bounding.
I have literally always noticed this even as a kid. I could never enjoy a movie as much as i could at home as apposed to a theater. Thats why i watch official releases at theaters and not at home with hbo max. I like the real deal.
@@awdadwadwad1723 The standard blu rays have the same colors, UHD Blu Ray supposedly bumps it up to 10 bits per color. Theatrical releases often are even higher definition than you can find on any disk, plus if you go to an obscure enough movie you'll get the big screen and speakers to yourself :)
1. Computer colour encoding usually follows a more or less exponential gamma curve, modelled after the brightness you'd get for a specific relative voltage on a CRT screen. This messes with a lot of things but is one of the reasons dark content looks worse. 2. Video colour encoding throws away the values between 0-16 and 235-255 to account for under- and overshoot in digital representations of analogue video. The remaining values are then stretched to the full 0-255 range by your video player, creating additional banding beyond the banding already created by not using the full range, and by only using 8 bits. 3. Both of these problems can be easily masked to the point of being invisible to the naked eye through debanding and dithering in the video player, something most modern devices are powerful enough to do in real time. However, up to this point they've mostly been niche features in videophile-oriented software like madVR, and unavailable in web browsers.
And on number 2 what encoding are you talking about specifically. There are tons of them and most of them are adjustable in many aspects, including color.
Lots of video is encoded not in RGB, but in Luminosity and two chroma components where the chroma components are then subsampled to compress the video even more with less visual quality degradation when compared to similar compression ratios over RGB space.
@@davidflores909 I'm referring to limited range YUV encoding, which encodes the Y channel (luma) in values 16-235 and clips off the remainder. This is what the majority of video formats use, including RUclips.
Muf Yes, gamma encoding is an important and little understood aspect of all digital still images and video. The human eye sees on logarithmic scales, which approximates the gamma function over most of its range, but does poorly in dark areas. You never see banding in bright areas, no matter how compressed the image.
@@inazuma-fulgur Saw it immediately when it came up. Reacted when Tom said there wasn't any colour banding when I could clearly see it. Have an ok monitor.
I’ve finally found a video that explains what I’ve spent hours and hours explaining albeit rather poorly to friends of mine regarding banding. Thank you so much for putting this up on RUclips
Or your screen is either improperly calibrated, or the screen just sucks. Remember, it only looks as good as the weakest link in the chain, which for most people is their display.
This video was amazingly well done. Everything was perfectly laid out in an easy to understand format, and then scripted and edited to perfection. It must be a lot of hard work to plan this out so that each piece not only flows and fits together, but complements each other too. Tom is extremely talented.
Isn't it funny, that higher resolutions and more colors aren't the answer to everything? I still love that ancient GIF format, doing aninmations in it. It is a joy for me, not only working out which colors to be picked, but also playing around with how little colors I can use (so dropping file size) while still looking nice. Afterall, 16 bits retro graphics do have their appeal and will always have. Limited abilities with graphics certainly don't equal bad.
Thank you Tom!!! this question was driving me nuts. I have an absolutely incredible and very expensive screen on my laptop and it kills me that all the dark and gloomy shows look rubbish no matter that I do😭 at least now I know it is not due to my hardware. I just need to switch back to physical media.. oh damn.. they all went bankrupt didn't they🥺
Quite literally the bane of Google Stadia and cloud gaming. Bitrate can help overcome some compression but this is by far the biggest change between even buffered streamed video and “live” cloud gaming video, let alone local render.
This is one of Tom's all-time best videos. Explaining a complicated topic with simple and conversational (but accurate!) language and *chef's kiss* perfect illustrations.
this video just blew my mind , I was noticing the pixelate in dark area in youtube and netflix videos no matter the video resolution and have done research everywhere to find the fix for this, but it turn out just how the compressed streaming video work, the same movie stored on my hard drive and played on the local video player doesn't have the issue with the version on netflix. also the editing quality of this video is just excellent, 1 instant subed!

I just remember my parents changing the brightness level mode on the TV so many times. *my mum pausing movie in very intense bit* "oh my GOD IT'S SO DARK"
This is why, when I know it's going to be a dark movie/TV show, I get it on 4k bluray instead of streaming it.
It's still not perfect and it depends on the quality of the transfer, but for the most part, it looks way better.

@@AluminumHaste Once you watch 4k blu rays on a good HDR display there's no going back. Maybe one day streaming services will have better compression and higher bitrate instead of using a video codec from 2003.

That's just David F. Sandberg's video about Darkness in Horror movies (he's known as *ponysmasher* on RUclips)
It's not a blocky mess in the cinema. Instead of 8 bits per channel, you get 10 at a minimum, with the option to support up to 16, and the bitrates are upwards of 250 Mbps, so you have a much greater raw colour space and little need for compression. In fact, DCI compliant cinema compression is very efficient, but lossless.
Monster movie directors don't care how it'll look on TV.
so when you see the background getting more detailed, that means something's coming

"and no one will ever notice the background"
People who edited and gave effort for background to look good: Dude wtf
Unless you're a matte painter, how much effort are you _really_ putting into backgrounds?
Sometimes not noticing the background is the point. You need to make it look good enough that people don't get distracted by it, or don't even notice that they're noticing it. That takes skill on its own.
Nah they know exactly what he's talking about and actually count on it.
(btw, I know you are being funny)
But with design, that's the point. If you don't notice it, then the hard work paid off. If you do notice and it isn't right, then a lot of work for nothing. Things in the background probably get the most work than the things in the foreground. Most things in film and design, if you don't notice it, that means they did their job.

@@IstasPumaNevada Hiding things in plain sight.
And then there are the potato recordings used for 99% of ghost captures, which are then compressed to 140p, and ripped off each time crushing the quality until you are left with grey mushy soup.
Thats becuse the ghosts refuse to be seen on any high quality video. It scares them off.

So my eyesight isn't blurry. Everyone is just doing a massive amount of dithering.
Well, kind of, I guess. I mean, maybe.
@Luc Bloom Depends. Strictly speaking the process of dithering trades resolution for more apparent colour.
This isn't so obvious at high resolutions, but if you look at a dithering pattern as you would've seen it on very old computers you do lose effective resolution using dithering techniques.
There's no free lunch here...

The nice thing about HD physical media like Blu-ray, is that it plays the video at a very high bitrate allowing for those dark scenes to actually look like it was intended.
Yep, they range from 25 to 150GB. Massive discs for massive quality. Specially those using HDR at 4k.
There should be an option for those with super-fast internet to stream in the same quality as Blu-Ray, with a super high Bitrate. It's sad but Blu-Ray is still the only way to watch movies in the best possible quality :(
@@danielbaugh2170 the streaming servers have to process that. It consumes CPU cycles, internet bandwidth and memory. It also saturates the network for ISPs. They are not going to give you that option. We are still far from Blu-ray quality streaming.
That's why Blurays are still superior to even "HD" streaming services. A lot of people don't know about or underestimate the effect of bitrate compression artifacts. I always notice it, especially here on RUclips. The bitrate limit for a 1080p video here is painfully low.

Thanks for this easy-to-digest explanation of this phenomena. I deal with this kind of noise constantly in videos, and the inclusion of scanlines in those areas on top of the lower-bitrate they typically receive on top of the re-encoding by youtube to an already-compressed video, can make for some really weird visual anomalies that hopefully our codecs and hardware can get better at dealing with in the future.

Omg I remember learning about this in school! It took the teacher over 8 lessons just to explained what this guy explained in 6 minutes!
because the teacher explained it in a way more detailed fashion, didn't have time to plan a script for the lesson for months, and also because you already knew about it that Tom's explanation was more simpler to you
i love ur pfp
@@ananttiwari1337 No, they didn't have months to plan a lesson. They've had the entire time that they've been teaching to come up with a lesson. The detail part could be true, but there's not much more to it than the compression engines tend to compress darkness at a noticeable level. The video described what the compressor did as well, and in a way that's universally understandable for most people since it explains all you need to know. Sometimes teachers aren't efficient at what they do but it's okay, there are a lot of things that teachers teach and explain that most 6-10 minute videos will never cover, this just isn't one of them.
@@Saneec (Assuming we're talking about school teachers and not university professors and also basing what I'm saying on school in my country which might be completely different from others) I think part of the reason why the teacher took much longer than Tom to explain is that the teacher didn't have fancy animations that show what they're explaining, and everyone in the class needs to understand so of course if someone wasn't listening or if someone couldn't understand the teacher would need to explain it all again. Also obviously a teacher can't be expected to spend a month to work on a script to explain something (to sometimes as much as 30 people) and in such a short time for every single thing they need to explain

I legitimately was wondering about this the other day. As someone who studied film/post production, I knew about 90% of the answer but just hearing it from you makes it a lot clearer and visually justifiable.
I agree. I already knew about this but when explaining it to my uneducated parents, they seem to think I'm imagining things. Hopefully this video will clear it out to them.
Tom Scott is the kind of guy who tells you what you wanted to know for a long time without asking.
Tom, I know you had your reservations about people helping, but your work has been great lately. I think this lets you focus on doing your part to make the videos great, and they come out even better. I'm very happy for you and excited to see what happens next!
Thank you perfectly explained! I always wondered why my videos looked relativ good on my hdr monitor but when uploading on youtube the darker scenes are always are terrible blocky mess, now I know why.
I've watched this video a few times.. and and I must say, this was SO well done with the visuals actually showing everything you need. This can just as well be a teaching tutorial in how to use visual aid to enhance the learning of a concept.
I second that. But Tom also hired a professional animation designer, it was certainly worth it. I have done something similar (with less flashy animations though)about the various image formats a long time ago. For who's interested in this, it's really fun to work with and to watch content about it.
Does the fact that I can still see the color banding on the blue gradient say good things about my eyes or bad things about my monitor
Both, really.
i dont really think it says anything its just not as noticeable as dark color banding
I mean it also depends on wether that gradient is more on the lighter side or the darker side
Idk I notice it very easy
It means your monitor brightness is too high.

@@awdadwadwad1723 The standard blu rays have the same colors, UHD Blu Ray supposedly bumps it up to 10 bits per color. Theatrical releases often are even higher definition than you can find on any disk, plus if you go to an obscure enough movie you'll get the big screen and speakers to yourself :)
1. Computer colour encoding usually follows a more or less exponential gamma curve, modelled after the brightness you'd get for a specific relative voltage on a CRT screen. This messes with a lot of things but is one of the reasons dark content looks worse.
2. Video colour encoding throws away the values between 0-16 and 235-255 to account for under- and overshoot in digital representations of analogue video. The remaining values are then stretched to the full 0-255 range by your video player, creating additional banding beyond the banding already created by not using the full range, and by only using 8 bits.
3. Both of these problems can be easily masked to the point of being invisible to the naked eye through debanding and dithering in the video player, something most modern devices are powerful enough to do in real time. However, up to this point they've mostly been niche features in videophile-oriented software like madVR, and unavailable in web browsers.
1. the gamma curve creates more dark colors at the expense of light ones. Not sure what you're on about here.
And on number 2 what encoding are you talking about specifically. There are tons of them and most of them are adjustable in many aspects, including color.
Lots of video is encoded not in RGB, but in Luminosity and two chroma components where the chroma components are then subsampled to compress the video even more with less visual quality degradation when compared to similar compression ratios over RGB space.
@@davidflores909 I'm referring to limited range YUV encoding, which encodes the Y channel (luma) in values 16-235 and clips off the remainder. This is what the majority of video formats use, including RUclips.
Muf Yes, gamma encoding is an important and little understood aspect of all digital still images and video. The human eye sees on logarithmic scales, which approximates the gamma function over most of its range, but does poorly in dark areas. You never see banding in bright areas, no matter how compressed the image.

This video was amazingly well done. Everything was perfectly laid out in an easy to understand format, and then scripted and edited to perfection. It must be a lot of hard work to plan this out so that each piece not only flows and fits together, but complements each other too. Tom is extremely talented.
As an artist who works a lot with high contrast, few colors, and rough details, I quite like the color banding that happens in compressed videos.
Isn't it funny, that higher resolutions and more colors aren't the answer to everything? I still love that ancient GIF format, doing aninmations in it. It is a joy for me, not only working out which colors to be picked, but also playing around with how little colors I can use (so dropping file size) while still looking nice. Afterall, 16 bits retro graphics do have their appeal and will always have. Limited abilities with graphics certainly don't equal bad.
