ValueError: zero-size array to reduction operation maximum which has no identity about auto-editor

[WyattBlue]

To effectively address this issue, I need the full traceback with line numbers and everything. Only putting the error message in the title is not enough.

Also, can you post the output of auto-editor info path-to-your-file.mp4? This information will help narrow down causes.

my bad, also here's what I got from doing info:

Oops just realized that I should've probably sent them in the code format. I can send them again if you need me too

[WyattBlue]

So your video is 19 minutes long and the fps is 90000!??? That is an obscenely high fps. Is that intentional?

[WyattBlue]

I think you can get your video working by simply adding the option '-fps 30'. This makes auto-editor output the video at a standard 30 frames per second, instead of its original, excessively high frame rate.

I'll also check for this in code and output an error message that tells exactly what's wrong.
