      What a coincidence I cleaned my screen today. But you're right, when your screen is dirty, it sometimes ruins the content on the screen. I mostly don't notice it though.
      Now I wonder, what is it that makes our monitors dirty? (I'm talking about non-touchscreen computer monitors here)

    This always made me angry when it comes to windows wallpapers. The image preview looks fine, but when you set it as a wallpaper, windows compresses the image very heavily (even on PCs that have loads of RAM and graphic memory), and makes evey dark wallpaper look extremely bad. Not to mention Windows 10 and 11 does even worse job, and you can see compression on their stock wallpapers. All because Microsoft wants that stupid mobile market.

    • @DasAntiNaziBroetchen
      @DasAntiNaziBroetchen 2 года назад +87

      That's why I used to circumvent this by putting the files in the wallpaper folder myself, so Windows doesn't do it for me while also compressing it.
      BTW: This has nothing to do with RAM and VRAM.

      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.

      RUclips videos are just full of color banding and compression artifacts.
      Sometimes i do regret buying this monitor, because it often makes things looking worse than better, because you start to see how terrible the youtube video codec actually is.
      Or MP4 / H264 in general.
      I wish there would be some setting which would me allow to watch the video in the originally uploaded non-compressed format or in HEVC high tier at least.

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.

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.

      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.

      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.

    I used to work for Sharp Labs - this issue was a problem when DVDs came out - they didn’t have enough colors compared to the LCDs we were making. The researchers were able to add image processing to the display pipeline to smooth the gradients. The Abyss movie was one of the reference movies because it had such bad banding in the dark. The algorithm had to identify the foreground and background and smooth out the background.
    Once Blueray’s came out the dynamic range of the source and the display became rematched. But then, we moved to streaming 4K and also TVs had to become cheaper. It can still be done probably.

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

    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.

      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.

      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.
