"Just because you can, doesn't mean you should."

My original post explained how to determine where the runs of black are, using ffmpeg (libavfilter)'s "blackdetect." The only piece left is applying the edits in a practical fashion.

Rolling your own with opencv would be a whole lot more work. I'm not entirely sure that I agree with Carl Eugen that ffmpeg isn't a video editing tool, but if it's not, Python certainly isn't. Yes, you can make it work. But you're going to spend a lot more time doing it than if higher level tools were used.

The goal here is for higher-level tools, not lower-level ones.

Or I might just end up using ffmpeg to split it into 7,000 files and then concatenating them. That's hardly the worst thing in the world.
