This is a smart question for a useful feature that I would make use of in a variety in professional post-production context.

Marco, thanks for posting.  I don't have an immediate solution but perhaps the concatenation feature using properly-dimensioned black still images might work

The ffmpeg gurus, will know better and likely have a genius solution.  Looking forward to seeing what comes of this.
