1. run pip install moviepy, make sure the version is 1.0.3
2. if the new error says ffmpeg not found, run sudo apt install ffmpeg, make sure moviepy know where to fint ffmpeg

In case you're using brew on an m-series mac and having trouble fixing, here's what I did:

1. Install ffmpeg version 4 with brew install ffmpeg@4 as suggested in Not compatible with M1 chip Zulko/moviepy#1867 (comment)
2. Check that ffmpeg 4.4.4 (latest version for ffmpeg 4) is installed. Mine was installed at /opt/homebrew/Cellar/ffmpeg@4/4.4.4/bin/ffmpeg
3. Create or add the following environment variable to your .env file, which will be read by moviepy.

FFMPEG_BINARY="/opt/homebrew/Cellar/ffmpeg@4/4.4.4/bin/ffmpeg"

4. Check that moviepy loads ffmpeg successfully with the following python script

from moviepy.config import *

if try_cmd([FFMPEG_BINARY])[0]:
    print( "MoviePy : ffmpeg successfully found." )
else:
    print( "MoviePy : can't find or access ffmpeg." )
