  • FFmpeg subtitle filter set start time

    31 décembre 2020, par CasualDemon

    I am trying to burn-in subtitles for a shorter section of a video, but using the subtitles filter always starts from the beginning of the subtitle stream, not at the specified start time, even when copying from the same video.

    


    So for example if I start an encode 10 minutes in to a film, the video will properly be set from there, but the subtitles will start from the beginning (10 minute offset in this case).

    


    ffmpeg -y -ss 600.0 -to 660.0 -i movie.mkv -filter_complex "[0:0]subtitles='movie.mkv':si=1[v]" -map "[v]" -c:v libx265 -crf 22 output.mkv


    


    This is not a problem when using picture based subtitles and the overlay filter, such as :

    


    -filter_complex "[0:0][0:2]overlay[v]"


    


    It seems to only affect text based subtitles. I don't know if this is just not possible and will require another solution, or if I am approaching it wrong. Any help is appreciated !
