It encodes faster than x265 in some situations with so much space saved
on ffmpeg?
I tested it like 6months to a year ago I think, and it had similar storage requirement at similar visual fidelity but transcoding took what seemed 5x to 10x the time
/e: for future reference, I'm testing a transfer to transcoding to AV1 instead of hevc
general gist:
preset is encoding speed, higher is faster, this setting gets me a bit faster than what i had my hevc encode set up
tune=0 tunes for being good looking
fast-decode lessens cpu use on decode
crf 50 seems fine for my use
-g 240 changes keyframe insertion to every 240 frames
-pix_fmt yuv420p10le gives 10bit color depth which helps with dark scenes and doesn'T cost much space
