![]() More documentation about -itsoffset can be found here.Īlternatively, you can use the Shift Times tool in Aegisub (Timing > Shift Times) and specify a time of 0:00:01.05 to try and correct the timing there. Note that -itsoffset 0.045 MUST come before the -i FILE argument since itsoffset DELAY argument modifies inputs after it. and see if that prevents your subtitle delay. As a result, I added -itsoffset -0.045 right before my -i input_file to re-sync the subtitles.įor your case, assuming that you have a similar frame rate, you can try ffmpeg -itsoffset 0.045 -i "Original.mkv". With a 23.98 fps input, I was able to find that a delay of 0.045 (using 1/23.98 = 0.0417014178, and some testing) would work with correcting my early subtitles. I've experimented with the -itsoffset flag, which allows you to adjust the input file's time offset. Aegisub saves subtitles with timecodes (not frame numbers), and it's possible that Aegisub's timecode does not match what FFMPEG considers to be the correct timecode, resulting in the off-by-one frames. It's likely a rounding error - it's something that I've encountered too. In aegis sub, the video looks well which the subtitle appear normally, however when played using MPC, the subtitle always late 1 frameĪnyone know why this happens?
