How do I make asetpts work? I have 4 audio files: '1a0 .flac' '2a0 .flac' '3a0 .flac' '4a0 .flac' I make 4 new audio files: '1a0.flac' '2a0.flac' '3a0.flac' '4a0.flac' made like this: ffmpeg -i "1a0 .flac" -filter_complex "[0:a:0]asetpts=PTS+6006[a]" -map "[a]" -c:a:0 flac "1a0.flac" ffmpeg -i "2a0 .flac" -filter_complex "[0:a:0]asetpts=PTS+16016[a]" -map "[a]" -c:a:0 flac "2a0.flac" ffmpeg -i "3a0 .flac" -filter_complex "[0:a:0]asetpts=PTS+38038[a]" -map "[a]" -c:a:0 flac "3a0.flac" ffmpeg -i "4a0 .flac" -filter_complex "[0:a:0]asetpts=PTS+76076[a]" -map "[a]" -c:a:0 flac "4a0.flac"
I'm trying to shift audio by '1a0 .flac' 6006 aticks = 0.125125 seconds '2a0 .flac' 16016 aticks = 0.33366666666666666666666666666667 seconds '3a0 .flac' 38038 aticks = 0.79245833333333333333333333333333 seconds '4a0 .flac' 76076 aticks = 1.5849166666666666666666666666667 seconds The PTS additions make no difference. Binary comparison: _OLD_FILE_ _NEW_FILE_ '1a0 .flac' and '1a0.flac' are identical. '2a0 .flac' and '2a0.flac' are identical. '3a0 .flac' and '3a0.flac' are identical. '4a0 .flac' and '4a0.flac' are identical. I add "expr=" and try again. ffmpeg -i "%_JOB_%1a0 .flac" -filter_complex "[0:a:0]asetpts=expr=PTS+6006[a]" %_COPYa_% "%_JOB_%1a0.flac" ffmpeg -i "%_JOB_%2a0 .flac" -filter_complex "[0:a:0]asetpts=expr=PTS+16016[a]" %_COPYa_% "%_JOB_%2a0.flac" ffmpeg -i "%_JOB_%3a0 .flac" -filter_complex "[0:a:0]asetpts=expr=PTS+38038[a]" %_COPYa_% "%_JOB_%3a0.flac" ffmpeg -i "%_JOB_%4a0 .flac" -filter_complex "[0:a:0]asetpts=expr=PTS+76076[a]" %_COPYa_% "%_JOB_%4a0.flac" The PTS additions make no difference. Binary comparison: _OLD_FILE_ _NEW_FILE_ '1a0 .flac' and '1a0.flac' are identical. '2a0 .flac' and '2a0.flac' are identical. '3a0 .flac' and '3a0.flac' are identical. '4a0 .flac' and '4a0.flac' are identical. asetpts is doing nothing. How do I make asetpts work?
