You'll have stopped the Encode and it will resume when you come out of sleep mode, but you shouldn't have 'totally screwed it'
So it essentially just paused it, like the actual pause button in Handbrake?
As far as I'm aware, yes.![]()
There is a "Put computer to sleep when encoding is finished" setting in HB's preferences you can use though which will put it to sleep *after* the encode is finished.
