Question

I am facing a problem with the cutout() tool in the moviepy library. The problem is when i use cutout() it cuts the audio from the end of the video. for example: if I do this

clip1 = VideoFileClip("wow.mp4").cutout(2,4)
clip1.write_videofile("wow2.mp4")

it will 2 seconds from the end of the video. note: wow.mp4 is a 13 seconds video.

This what I see in the audio part when it runs. It doesn't continue until 100%:

Moviepy - Building video wow2.mp4.
MoviePy - Writing audio in %s

MoviePy - Done.

Answer 1

I found a solution !

Essentially what you want to do is just go into your

python3/site-packages/moviepy/decorators.py

On line 45 change

- new_clip.audio = func(new_clip.audio, *args, **kwargs)

to

+ new_clip.audio = func(clip.audio, *args, **kwargs)

save file.
