in addition to manolito's hints, I would add that LAV Filters lets you to
decode using your GPU capability. Usually it does not lead to improve encoding time, but you will have your CPU free for other tasks, and your CPU fan much more silent...
@manolito
thanks for highlighting the FFmpeg 4:2:2 chroma subsampling issue. I will add the "-pix_fmt yuv420p" flag to FFmpeg safe mode in the next release.
Thanks also for the suggestion how to use the more recent FFmpeg releases with A2D.
And thanks also for the updated FFmpeg VBR plugin!
2.8.5 Final should be released before Xmas.
Bye
