Comment (by navilor): I have uploaded the file "decimate-allows-EIA-608-captions-to-pass- through-S01E01.vob" via the upload page you provided. I now have additional information and moved the -r option to before the video codec. When I run the following command line using CRF captions do not come through. ffmpeg -t 00:05:00 -i decimate-allows-EIA-608-captions-to-pass-through- S01E01.vob -vf yadif,decimate,dejudder -pix_fmt yuv420p -vsync 1 -threads 0 -r 23.976 -sn -vcodec libx264 -g 48 -crf 23 -preset veryfast -profile:v baseline -tune film -x264opts no-scenecut -an -map_metadata -1 -f mp4 -y S01E01-script001.mp4-video.mp4 When I run the exact same command except I encode to bitrate captions pass through for both single and two pass encoding. ffmpeg -t 00:05:00 -i decimate-allows-EIA-608-captions-to-pass-through- S01E01.vob -vf yadif,decimate,dejudder -pix_fmt yuv420p -vsync 1 -threads 0 -r 23.976 -sn -vcodec libx264 -g 48 -b:v 808385 -bufsize 1415985 -maxrate 1010481 -preset medium -profile:v high -tune film -x264opts no- scenecut -an -map_metadata -1 -f mp4 -y S01E01-script001.mp4-video.mp4 -- Ticket URL: <https://trac.ffmpeg.org/ticket/7055#comment:7> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://ffmpeg.org/mailman/listinfo/ffmpeg-trac
