[FFmpeg-user] insert one frame

[Alexey Astakhov]

Hey ffmpeg-users,

I have kind of a simple question - is there a way to insert one frame at
specific time into video using ffmpeg? Or duplicate one given frame?

The obvious way is to cut video in two pieces, and then concatenate first
part, frame and second part. But I don't know if it would produce missing
frames, and it's all about accuracy (we need to sync 100fps videos....)
Or if some other software can do it?

Thanks a lot,
Alex
