Google uploaded a 10-hour video of confetti falling

Just for fun I guess. But maybe to sort of prove that snow and confetti basically ruin video compression on YouTube.

Why snow and confetti degrades YouTube video quality

Hmm, I've never really noticed this, but now I can't unsee it. Tom Scott explains in a very clear way why moving bits in video can sometimes degrade YouTube video quality. It has to do with how much information is compressed in a streaming video and how that information is channeled to users' computers across the internet. More moving parts in a video mean more data. But with a bottleneck of speed, that video can sure start to look crappy.
