![]() ![]() Hardware, however, was only part of the battle. Fortunately, I have a 2011 iMac that may be getting a little long in the tooth otherwise, but turns out to be just the right age for this little adventure, so I didn’t have to run out and buy an external drive for this project. You authored some content in iDVD, popped in a blank disc, and burned away.īut that was then-these days, iDVD is long dead and Apple barely even ships a Mac with a DVD drive. I probably haven’t burned a DVD in a decade, but back in the day, this was pretty straightforward. (A digital file would have been easier, to be sure, but her setup doesn’t make watching that super easy, and there were other considerations, which I’ll go into in a bit.) It occurred to me that there was a particular video she’d wanted in DVD form. This example will overlay the fourth subtitle stream over the second video stream, and stream copy the seventh audio stream: ffmpeg -i input.mkv -filter_complex "overlay" -map "" -map 0:a:6 -c:a copy output.Note: This story has not been updated for several years.Ĭhristmastime was rolling around, and I was looking for a gift for my mom. Note that this requires re-encoding, so it will by much slower than using softsubs.īasic example using default stream selection behavior while stream copying the audio: ffmpeg -i input.mkv -filter_complex "subtitles=input.mkv" -c:a copy output.mp4Įxample to use the third video stream, fifth subtitle stream, and first audio stream: ffmpeg -i input.mkv -filter_complex "subtitles=input.mkv:si=4" -map "" -map 0:a:0 -c:a copy output.mp4Įxample for a separate subtitle input file ( your-subtitles-file.srt): ffmpeg -i input.mp4 -filter_complex "subtitles=your-subtitles-file.srt" -c:a copy output.mp4 Use the subtitles filter to "burn-in" text based subtitle formats (SRT, ASS, VTT, etc).

How can I convert the video, keeping the subtitles, or add a subtitles. I have a MKV video I want to convert to MP4, but every which way I try and convert it (Handbrake, WinFF, FFmpeg, MEncoder.) I lose the video's subtitles. ![]()
