I Coded a Video Editor (and it kind of sucks)

I was using Manim to create animations for my latest video when I ran into a bug. This bug was very small, but caused a visual artifact that was driving me crazy. I reached out and was informed that this was a known bug, and unfortunately there is no fix. I said to myself, “Fine I’ll live with it“, but I couldn’t. So I set out to code a video editor over my weekend, and here I am 8 months later with my shiny video editor that was an absolute pain to use to make this video. Hopefully you enjoy my overview of the process.
