Dark scenes in television, YouTube, and streaming platforms all look pixelated and blocky. Here's why.

    I can promise there are no jump-scares in here. And yes, I finally got an animator to do in a couple of days what would have taken me a couple of weeks...!

    It looks even worse once you realise how dirty your screen is
  • @CadenButera
    “256 Shades of Green” is the boring spinoff of a franchise we never asked for
  • @frailty7280
    0:42 no way this dude just sneakily taught us how greenscreening works entirely in the edit
  • @magalhaes753951
    I actually noticed that if I add noise to my RAW photographs I can reduce color banding, but never knew why
  • @Nugcon
    I bet people in the future will intentionally add banding as "2010's aesthetic"

    He's really mastered how to present a topic , his 6 min video feels like a 2 min video
  • @masonlevine4356
    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.

    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!

    "why its blocky in the dark" me watching in 144p so my PC can run: huh
  • @draxle176
    Me a colourblind person: watches video of a guy in a brown shirt talking about colours that don't exist
  • @prabhakarrao4922
    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 YouTube

    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.

    I'm a graphic designer. Crying over color banding is my job.
  • 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.

    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.
  • @Thinking-OutLoud
    "why doesn't the bright background have colourbanding?" me, sobbing: IT DOES, RIGHT THERE, I CAN SEE IT
  • @FrancSchiphorst
    The freaking level of detail in production, adding a bit of reverb when showing the movie theater.... Awesome!
