[FFmpeg-user] Create a black box over top of the video for a set duration at a set time.

[David Niklas]

Hello,
What I'd like to achieve is sort of like censoring, but with a black box.

I can find plenty of examples of how to add a black box to a video, but
the problem is it is always either the whole video, or only at the
beginning/end, that the examples add black boxes to. I cannot seem to
figure out how to set the start and end timestamp.

Thanks,
David
