This filter requires ffmpeg to be compiled with -enable-libass. Same as the subtitles filter, except that it doesn’t require libavcodec and libavformat to work. For example, if you wish to start both the output video and subtitles to start 5 minutes into the input file, then you can use a command line this:įfmpeg -ss 5:00.00 -copyts -i video.avi -ss 5:00.00 -vf subtitles=subtitles.srt out.avi If you want the burned-in subtitles to start at the same timestamp as the video, you will need to copy the timestamps to the output with -copyts, and then additionally seek in output again with the same values that were used for the input. Note that the subtitles video filter opens the file separately, so if you are also Seeking in the same step, then the subtitles will start at the beginning of the subtitle file.
