Update ffmpeg.go change preset from slow to medium #427

Closed Tibia2000 closed 1 week ago

Tibia2000 commented 1 week ago

Updated the FFmpeg preset from slow to medium because the increased computation time required for slow does not provide a significant visual quality improvement. This change optimizes the balance between performance and quality. image

LGTM but would also like input from @leszko since he is the one who made the original change to improve quality

Also wanted to confirm that this does result in a measurable speedup for GPU with our benchmark tools?

Yes it does, performance hit with slow is over 50%: image image
