With my own new and faster hardware in box running a matured and updated
openSUSE Tw Slowroll (system overview at the bottom here), I have
updated and extended my own transcoding tests using ffmpeg-7 and SVT-AV1
v. 2.1.
For SD DV 576i -> AV1 the speeds increase from fps=50 at preset 4 up to
fps=890 at preset 12, compressed file sizes 6-8%
For HDV 1080i -> AV1 the speed increases from fps=24 at preset 4 up to
fps=376 at preset 12, compressed file sizes 16-18%
