I accidentally did this when getting into skateboarding edits. My player is set to default to 1.75x speed. I happened to watch a video on a new browser or something and literally thought gravity was acting differently for a sec because how much more airtime they were getting then I realized I had trained a misperception of gravity into myself.
Woah, I just got an ad for this today, and was intrigued enough to see what their monetization model was (in app purchases/subscriptions for “pro” features) and took a big pass on it.
