OSError: MoviePy error: failed to read the first frame of video file C:\65D3.mp4. That might mean that the file is corrupted. That may also mean that you are using a deprecated version of FFMPEG. On Ubuntu/Debian for instance the version in the repos is deprecated. Please update to a recent version from the website.

Yes you can ignore that warning. It just means that moviepy was expecting one extra frame at the end of the video that wasn’t there, so it duplicated the last frame instead. There’s been quite a few changes in this bit of moviepy’s code since 1.0.3 so it might be fixed in 2.0 anyway.

Your video file may be corrupted, you can check it with ffmpeg.
