BTW, I can use ffmpeg to cut the sample video file successfully,

ffmpeg -i file_example_MP4_480_1_5MG.mp4 -ss 10 -t 5 new_example.mp4

[Breakthrough]

It seems that OpenCV is failing to open that video. You can try using a different backend like PyAV:

scenedetect -i file_example_MP4_480_1_5MG.mp4 -b pyav split-video

Can you try that and/or MoviePy and let me know if that works for you?
