ZeroDivisionError: float division by zero

i don't know what the problem is here. something seems to be wrong with my input video, but the error doesn't give me any more information. it's a mp4 with 5:06 length. i have started to work with wav2lip yesterday and successfully processed one other video (which was captured from the same camera, same resolution etc, but it was a lot shorter (9sec for testing).

for this video, i used handbrake to crop the part where the actual mouth movements will be, then saved it with constant framerate and web-optimized mp4. i've tried it a couple of times now, with new versions of the video, better quality, web-optimized yes/no, different croppings. the audio is exactly as long as the video.

i know moov atom has something to do with corrupted / unfinished video files, but this is definitely not corrupt, since i've re-rendered it multiple times and made sure it completed.

also what's conspicuous: the preview image/player for the clip is black and it can't be played. with my other clip, a thumbnail was displayed and i could preview it. with this, it's black and i can't play it

could it be just too long? is there a max length? what else could i try to find out what's wrong here? like i said, a different video clip from the same camera with the same settings worked fine i appreciate any help

edit: tried again with the same video, re-exported via adobe premiere. same result..

Hi, Sorry about that It seems to come from the video input file. Can you senf me the file extension or eventually the file itself?

Thanks
