I get this error using the following parameter (probably again an issue with --grid 10x0) ... I got no such errors with the same mp4 file but with a regular 3x3 or 5x4 grid ...
... it seems to be caused by input files not long enough for even a single thumbnail ... i.e. using "--interval 1m" but the input file only being 40 seconds long.

I see this problem as well; it'd be really nice if we could have the option to, in this case, just grab a frame from the approximate middle of the video.
