ffmpeg creates subtitles delay
Hi everyone
I want to mux a .ass subtitles file into a matroska container together with a video stream. First I checked the .ass file in Aegisubs before muxing and I got the following timing on the individual subtitles lines: First text line from 00:14.49 - 00:17.83 If I now mux the .ass file together with a .mkv video file with mkvtoolnix I get the following timing on the first line (through checkingt he resulting .mkv with embedded .ass in Aegisub): First text line from 00:14.49 - 00:17.83 mkvtoolnix muxed the subtitles file exactly as it was when I checked the .ass file in Aegisub before muxing. When I tried to mux the .ass file together with a video.mkv file using ffmpeg and the following command, the subtitles timing gets messed up and delayed (through checking the resulting .mkv with embedded .ass in Aegisub): ffmpeg -i video.mkv -i subtitles.ass -map 0 -map 1 -c copy -output.mkv First text line from 00:14.44 - 00:17-78 In conclusion: When I mux with ffmpeg instead of mkkvtoolnix, I get delayed subtitles of - 0.05s. Has anybody else encountered this problem when muxing subtitles with ffmpeg. How can I avoid this and make ffmpeg mux the .ass file exactly as it is shown when opened in Aegisub without creating that 0.05s delay? Last edited by carlosrodriguez; 11th July 2020 at 14:58. |
