I made a program that creates the colour palette of a film

I saw these things originally on Reddit that extracted the average colour of frames from films and put them together to make a colour palette for said film, the original creator has a site called The Colors of Motion. I thought it would be cool to try and create a simple PowerShell script that does the same thing.

Here are a few examples:

Harry Potter and the Philosopher's Stone: https://i.imgur.com/6rsbv0M.png

I've hosted my code on GitHub so if anyone wants to use my PowerShell script or suggest some ways to improve it feel free. You can use pretty much any video file as input as it uses ffmpeg to extract the frames.
