Comment (by softworkz):

 Replying to [comment:10 Zach]:
 > This whole thing is working on the assumption that the captions have the
 same frame rate as the video.  The use case for this is edit suites like
 Premiere Pro that support exporting mp4 with sidecar .scc files but not
 embedded in the user data of the video stream.

 Yes, the use case is totally valid - no doubt. It's also not that it's not
 possible - the big problem is that this task doesn't really fit well into
 ffmpeg's architecture.
 Have you tried libcaption? Maybe a standalone tool for this specific task
 is a better (and much cheaper) option...
