Im going to be annoying and show you a free open source vibe coded project to make a point. The viewer part of this project predates AI, it took me years just to get the viewer to be great. I built this Video compositor in 2 days that does beat matching, parameter automation, shader effect layers, auto looping and a ton of other things I need when im video editing, cancelled my after effects account and doing this is something I do professionally. There is absolutely 0 chance of a single person doing that in a month, let alone 2 days, before Opus level models. Its not really cloned from anything other than my experiences doing video editing.
