fun fact: Hitfilm has an effect that makes audio wave visulaizers. It's also behind a paywall, I really wish tutorials tell you stuff like that.
So you have Vizzy.io to thank for sort of making the visualizer, the left side waveform didn't render in the export so I had to use a mirror effect. I also couldn't get the screen pump to work on Vizzy so I also had to do that, which meant I had to use a composite shot, which neither me nor my laptop like. Hitfilm crashed multiple times exporting this and I think I'll have to restart to fully fix it.
I'm also admitting I got the idea from Kyrlex on rule34video. They are different, really the only similarity is the game and keeping the 9:16 ratio. But I kind of feel bad since it was their first video, so do give them some support.
