===================== AV1 guide v14 ========================
Step 1 - Check VMAF with Ab-av1
1. AV1
Source resolution → crf-search -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --min-vmaf 98
1080p Downscale → crf-search -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --min-vmaf 96 --vfilter "scale=-1:1080"
720p Downscale → crf-search -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --min-vmaf 96 --vfilter "scale=-1:720"
Sample encode → sample-encode -i "c:\file.mkv" --pix-format yuv420p10le --svt fast-decode=1 --svt tune=0 --preset 5 --min-samples 20 --crf 20
2. x265
Source resolution → crf-search -i "c:\file.mkv" --encoder libx265 --pix-format yuv420p10le --preset medium --min-samples 20 --enc x265-params=fastdecode=1 --min-vmaf 98
1080p Downscale → crf-search -i "c:\file.mkv" --encoder libx265 --pix-format yuv420p10le --preset medium --min-samples 20 --enc x265-params=fastdecode=1 --min-vmaf 96 --vfilter "scale=-1:1080"
720p Downscale → crf-search -i "c:\file.mkv" --encoder libx265 --pix-format yuv420p10le --preset medium --min-samples 20 --enc x265-params=fastdecode=1 --min-vmaf 96 --vfilter "scale=-1:720"
