Dark scenes in television, RUvid, 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...!

8 bit RGB color is plenty. Video doesn't have 256 values per color for 8 bit YUV spaces. It's limited to 16 to 235. Video compression is the secondary problem. 10 bit video solves it, and newer color spaces also add to the help.

Sometimes, particularly during the pandemic, the background falls asleep then gets noticeably compressed.

Your second reason is not really valid thanks to something called "gamma" (not sure, but I think you already had a video about that and in that case I don't know why you brought up the second point). Brightness levels are not linear so with increase from 200 to 201 you get way higher brightness increase than from 1 to 2. Btw - dithering is not an option even in bright areas - it is basically random noise (should be, not alway really is) and that is incompressible.

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?

Good that you got an animator, because this would be a headache to put together. I have a headache after watching it. Off to bed to recover.

If you want to see the difference for yourself and you have an iPhone , take a screenshot at 3:24 save edit photo turn the contrast all the way up and then turn the brightness all the way up on the photos it’s cool

That game of thrones episode" the long night" made me realize why a dark war scene needs very high resolution to just even barely make out the details.

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?

Correction: There are 24 bits per pixel. The red, green, and blue lights in a pixel each have 8 bits.

At 3:28 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.
