First, we need to install the library with pip:
pip3 install moviepy
And then, create python file like this:
from moviepy.editor import VideoFileClip
videoClip = VideoFileClip("video.mp4")
videoClip.write_gif("video.gif")
In code above, video.mp4 is video filename, and video.gif is filename for the result. Next, run python file and wait until the process is finished.
Thank you.
