I can’t believe I didn’t write about this before. I usually do this, at least 2 times per month, and hey, now it’s on the blog for my future reference.
Simple Scenario: Open a video file and export each frame as an image.

- The video file must be in the same folder of the python file.
- Create a folder [IMG] in the same path to store the exported images.
Then you run it and have something like this
And a super simple piece of code
