At least the HBO logo decaying from analog noise to digital noise with compression artifacts makes sense. I'm also amused when they drop confetti and the screen turns into blocky slush. Another surprisingly hard to encode scene is water. Wave motion and shimmering is almost impossible to handle efficiently.

I guess unless your codec handles water physics. Which is not quite as absurd as it sounds. Have a look at the reflections in https://www.youtube.com/watch?v=udPY5rQVoW0 https://www.youtube.com/watch?v=udPY5rQVoW0

  Similarly whenever I take photos in the forest they come out looking like complete garbage. It occurred to me it’s the image compression completely falling apart. Color gets totally desaturated too.

    It's also that a forest is incredibly three-dimensional and layered, which contributes a lot to how you experience it. A photograph shows only a 2D projection of this, obviously. Capturing depth in a satisfying way in a photograph is a skill that can be learned, but often it's impossible. (The skill is really about learning to see the small set of perspectives that do translate meaningfully to a 2D projection.)

My photography teacher told us "If you can't see the same thing (that you see with your eyes) via the viewfinder, don't take that photo". It took me a decade to completely understand what she meant. One day it clicked at a very mundane moment, but it was pure enlightenment.

        But even the viewfinder is forgiving in this respect, because parallax allow you to sense depth through small perturbations of the position of the camera! So eventually, you will learn to imagine in your head what a scene looks like when projected onto a sheet of still paper. (Bonus: the parallax effect can be exploited to convey depth also on a print, actually. A comparatively long exposure time will, depending on light levels, emphasise or de-emphasise motion closer to the camera in motion blur effects, that vary in size and intensity depending on the two things above.)

I shot beautiful 4k telephoto video of hummingbirds cleaning themselves in a fast running stream and YouTube is totally unable to display the content at a satisfactory level. It’s such a bummer it was such a cool shot and I can’t really share it!

  Can you upscale it to 8k (not sure if Youtube supports it)? I'm often watching videos at a resolution larger than my screen can display just to get the extra bitrate.

    I can try! Thanks for the suggestion.
