Well, technically you can
ffmpeg -i input.mkv -vf "scale=640:360" -c:v ffmpeg -i input.mp4 -vf "scale=640:360" -c:v libsvtav1 -crf 28 -preset 3 -g 240 -svtav1-params tune=0:enable-overlays=1:scd=1:scm=0 -pix_fmt yuv420p10le -c:a aac -b:a 16k output_360p.mp4
gives me a 1633KiB file for a minute of video, and I’m unsure you’ll even notice it was compressed
@Slibowitz please link me example video for testing so we can compare and calc properly
