Not Idle BOTW

Have you ever wanted to speedrun watching a speedrun?  This channel uploads others' BOTW speedruns, but with all idle time cut out.  Full credit to the runner and a link to the original video will be in every video description.

How do I do this?  Well I don't do it manually -- I wrote a Python script using OpenCV2 and MoviePy that automatically detects when active gameplay is occurring. The algorithm is simple; if a reddish pixel is detected where the player's heart containers appear in the top left of the screen, the footage shows gameplay.  It's not perfect, but it works surprisingly well.
