BIG TUTORIAL - How to fix video posterization (banding) - and a lot more
▼▼ EXPAND FOR NAVIGATION ▼▼
00:00 Explaining the problem - "partial" video causes doubled and skipped values.
14:48 Trying to use digital noise to reduce banding (bleh)
19:08 Experimenting with other textures
23:34 Interlude: Nearest neighbor scaling: It's important, and Premiere doesn't have it.
19:08 Experimenting with other textures (continued)
28:47 Key insight: Order of operations matters!
30:44 Fixing banding in a video that was already rendered
32:39 Interlude: bicubic scaling vs. nearest neighbor
35:46 Fixing banding in a video that was already rendered (continued) Also, how to key a gradient and other complicated stuff
If you want to try this yourself:

1:06:13 - Discovering that YouTube uses different bitrates in the same resolution
(FYI, banding can also be called "posterization.")

In particular, this video was very useful for me to figure out how different sizes of the faux-pixels are affected by different resolutions in YouTube: https://www.youtube.com/watch?v=fLet97r56tE (I'd watch the whole thing with a different resolution each time)
