Use -vf yadif=1 as interlace filter to prevent interlacing artifacts: ffmpeg -i input.mpg -vf yadif=1 -c:v libx265 -crf 30 -c:a libopus -b:a 56k -frame_duration 60 output. generation video encoding formats is AV1, as the first compression format developed by the Alliance. The posts have been split up with this, the finale putting the fasts and slows presets from both H.264 with H265 HEVC together. For non-interlaced videos ffmpeg -i input.mpg -c:v libx265 -crf 30 -c:a libopus -b:a 56k -frame_duration 60 output.mkv For interlaced videos FFmpeg h264 & h265 preset crf comparison 2020 (finale) This comprehensive FFmpeg encoding comparison includes H.264 and H.265 HEVC from the fastest preset ultrafast through to veryslow with CRF values from 20 to 30. My recommendation is to use CRF 30 for lower-quality videos like analog grainy-ish videos, CRF 23 where you want to preserve the utmost quality, and CRF 26 for everything else. However, these are painfully slow, running at 0.0046x speed (libaom-av1) and 0.076x speed (libvpx-vp9) compared to 1.5x speed for libx265 for a test video since these encoders seem not to be highly optimized yet.ĬRF means constant rate factor, higher values mean better quality but larger file size. I also tried VP9 and AV1 which should result in even lower file size at the same quality. only x265 support copying that data through FFmpeg, no AV1 library does.
#Ffmpeg crf av1 archive
When you don’t want your video archive to eat up too much space, I recommend encoding them as H.265 and OPUS as these codecs provide excellent quality with typically less than half the bitrate of older formats. 1 x265-ARNOLD The New Mutants 2020 UHD BluRay HDR10 2160p. To produce capped CRF, you specify a CRF value and a maximum rate and buffer size, which are also highlighted in the MediaInfo screen above.
