Hi. I'm having this error that I don't know how to solve. Would you please help me?

After I try to render a video a pop up comes saying: List index out of range

Do you know what it means or how to fix it?

It must be having some problem extrating the frames. There is any files inside the original_frames folder?

I am having the same issue. I do select the file, the folder for the outcome but no matter which file I select (all are mp4) can't make it run. Thanks for helping. J
