Cutting out a portion of video - python

python video moviepy
Pranav Arora picture Pranav Arora · May 19, 2016 · Viewed 39.6k times · Source

I have videos of length approximately 25 min each and I wish to cut a few seconds from the start using python.

Searching about it, I stumbled upon the moviepy package for python. The problem is, it takes up a lot of time even for a single video. Following is the code snippet I use to cut 7 seconds from the start of a single video. The write process consumes a lot of time. Is there a better way to cut the videos using python? 

from moviepy.editor import *
clip = VideoFileClip("video1.mp4").cutout(0, 7)
clip.write_videofile("test.mp4")

Please let me know if I have missed out any details.

Any help is appreciated. Thanks!

Try this and tell us if it is faster (if it can, it will extract the video directly using ffmpeg, without decoding and reencoding):

from moviepy.video.io.ffmpeg_tools import ffmpeg_extract_subclip
ffmpeg_extract_subclip("video1.mp4", start_time, end_time, targetname="test.mp4")

If that doesn't help, have a look at the code
