Uncompressed 1080p60 video is on the order of 3gigabit a second

I guess hulitu meant to say "very, very aggressive compression with rather noticeable artifacts and banding which are hard to ignore even for a layman"
Maybe he means lossy compression
That 3gbit is already lossy compression (chroma subsampling, bit depth compromises, framerate and size compromises)

You could store at a more usable bitrate - say 240mbit, and its even more lossy

Does Vimeo compresses the uploaded videos? I found their videos to be more "clearer" if that makes any sense.
All video is compressed in a lossy manner.
I have some 444 10 bit progressive files, you could argue that the mere act of sampling an analog domain is lossy, but if you accept a typical YUV422 as being non-lossy then I have a fair amount.

But yes you're right that typically video today will be stored in the 150-250mbit range which is lossy.

I imagine a typical youtuber will then compress that again out of their video editor to something like a 20mbit long-gop file and upload to youtube/vimeo. That platform then takes the original upload and makes a dozen or so versions and different frame sizes, bitrates and codecs to cater for different consumers
