Why Dark Video Is A Terrible Blocky Mess

Dark scenes in television, IRgos, 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...!

    This happend a lot in GoT's "the long night", question is, taking in account that there are 4k screens nowadays, is it possible to increase the number of colours?

    This is why analogue signals are better than digital signals, I've been saying this for years. A good strong analogue TV signal will knock spots off an analogue signal for quality but according to the government who switched off analogue, digital is better.

    i’ve always noticed that there’s a lot of extra compression in the red channel on videos. often scenes in films that use mostly red look awful compared to the rest of the film. anybody have any insight why red is always the worst colour for compression?

    At <a href="#" class="seekto" data-time="208">3:28</a> when Tom is describing why you can't see the bands, and after he's already showed you what it could look like, I see lots of semicircular banding. It's distracting. Is this because of a possible technical error when they created the video? Is Tom showing what should be invisible banding but accidentally set the colors wrong? I wonder if anyone else has the same problem. To be fair, I always notice the black banding, too.

    Thanks for this video. Nice explanation. I cannot stand the banding. I find it very distracting from what I am watching. Perhaps after we are all gigabit connected, and slowly transitioning to what comes after, then the banding will go away? I won't hold my breath.

    <a href="#" class="seekto" data-time="195">3:15</a> "If we take a sample of the bright gradient behind me and MASSIVELY increase the contrast, you can see it's there, but normally it's invisible." No... it's not? Am I crazy or is it really easy to spot the color banding no matter the gradient?
