This works for me when recording from TV5 ffmpeg -y -i source.ts -ss $1 -to $2 -crf 22 -preset veryfast -g 50 -me_method umh -ab 96k -ac 2 -filter_complex '[0:v][0:s:0]overlay[v]' -map [v] -map 0:a -movflags faststart result.mp4 Note [0:s:0] instead of your [0:s] I don’t know if that’s the reason though. > > > And I get an error "sub2video: rectangle overflowing" which appears a number > of
