Moviepy: AttributeError: 'NoneType' object has no attribute 'stdout'

[bezerra-lucas]

Hello everyone

I am writing a script to merge short clips into a video, but these videos contain different sizes and frame rates. When I ran the code below, the output video was full of glitches from the second clip.

`from moviepy.editor import *

clips = [ VideoFileClip("clips/clip-1.mp4"),
VideoFileClip("clips/clip-2.mp4"),
VideoFileClip("clips/clip-3.mp4")]

final_clip = concatenate_videoclips(clips)
final_clip.write_videofile("final.mp4")`

Searching better I assumed it was possibly because they diverged in attributes, so I included the compose() method:

final_clip = concatenate_videoclips(clips, method='compose')
and got the error below:

If you're in trouble because this method is not working, just downgrade moviepy to the version 1.0.0
