>Most of the video you encode on a computer is actually all in software/CPU because the quality and efficiency is better.

That was the case up to like 5 to 10 years ago.

These days it's all hardware encoded and hardware decoded, not the least because Joe Twitchtube Streamer can't and doesn't give a flying fuck about pulling 12 dozen levers to encode a bitstream thrice for the perfect encode that'll get shat on anyway by Joe Twitchtok Viewer who doesn't give a flying fuck about pulling 12 dozen levers and applying a dozen filters to get the perfect decode.
