Why Dark Video Is A Terrible Blocky Mess

Dark scenes in television, DE-visions, 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...!

  • Color banding and the fade of a shade of color sound like the same thing.

  • Thank you for this! I bought a high-end, OLED monitor, and was so angry with the banding. I've very relieved to now know why.

  • You should do a green screen and turn it into a black screen and you can have a dark scene without this issue

  • 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.

  • 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 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 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.
