png's take an insane amount of time to decompress, they are incredibly slow to work with.
A bit part of codecs is not packing the footage into a small file, it's being able to unpack it at lightning speed.
edit: also at max compression, the slowest to pack & unpack, you're looking at 3mb per frame. that's 10gb a minute for a 60fps 1080p stream. I think to have that stable with no lulls is far beyond the reaches of fiber. 4k would be 40gb a minute.
in comparison, project stream/stadia used 5-7gb an hour, and it's apparently been optimized further.
