The corrected one can be added to an mp4 file with ffmpeg doing: ffmpeg -i source.ext -i source.srt -c:v copy -c:a copy -c:s mov_text -metadata:s:0:0 language=eng source-with-srt.mp4 If this srt is from a 29.97 recording and the source.ext is 23.97 or 25fps then this can be corrected with subs. Search for Subtitles-1.04.tar.gz by Karasik subs -h subs: convert, join, split, and re-time subtitles format: subs [options] subfile [ subfile ... ] options: -a coeff, - a and b coefficients in linear transformation -b time u=at+b, where t and u are src and dest times ( default(identity transform) is [a=1,b=0] ). -a can be set as ratio, f.ex. 23.9/25 -c codec - use codec to write file ( one of: 'srt mdvd sub2 smi idx' ) > > It is also better to mention that the original SCC file is 29.97 Non Drop > Frame. > > There is a webpage with lots of informations about the SCC file format, and > it may also be useful to FFmpeg crew to support this particular format. > > http://www.theneitherworld.com/mcpoodle/SCC_TOOLS/DOCS/SCC_FORMAT.HTML > > SCC file format is not the only Closed Caption file format, but I believe > it is the most popular. > _______________________________________________ > ffmpeg-user mailing list > ffmpeg-user@ffmpeg.org > http://ffmpeg.org/mailman/listinfo/ffmpeg-user _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
