Using the National Geographic Gimp Filter to postprocess video clips

Are you also a bit unsatisfied with movie editing programs like Kdenlive or OpenShot? In image processing programs like Gimp, you have such fine grained control and myriads of available filters to alter still images in every possible way. In contrast to that, movie editing programs like the ones mentioned above only offer you a handful of filters to create an individual look for your video project.

Fortunately it is quite easy to use a combination of ffmpeg and Python Gimp-fu to exploit all of Gimp's capabilities for batch processing video clips frame by frame. Here is a small example, where I applied Gimp's National Geographic Filter on a short clip. Depending on your system, you might need some patience, if you plan to process longer clips.

The scripts that were used to this can be found here. It is quite easy to modify it to use any other arbitrary set of Gimp filters, image processing operations, etc.
