I remember reading this article when it was new, and I left fully agreeing, but more broadly: modern video compression is magic.
Like, it's baffling to me how much we can compress high-quality video nowadays. HEVC and AV1 and VP9 are all also very cool and they still sort of break my brain. I understand how they work but it doesn't feel like it should compress as well as it does.
I've done AV1 encodes where I was convinced the conversion must have failed in some way for it to be that small, scrubbed through it and it all looks fine, watched through the entire thing to confirm that wasn't the case, just waiting for the shoe to drop, but then to find out, no, it's really just that good.
