My first question is how does rendering videos makes their size smaller? Does it reduce bitrate or something? Coz I had a 60 gig video and rendering it keep the same res. I got the output video file as 2.2 Gig.
And How long does rendering a 55 gig file take?
Does it usually take long?
Is it GPU dependent or CPU dependent?
Ty for all you answers...
