Video Editor boilerplate

Hey, everyone! I hope you guys are OK. I see all of these great video tools popping up with great functionality but I still see some similarities between them. Sometimes its a design hint, sometimes it is a workflow hint but I can't stop noticing they have some stuff in common. That makes me think that there might be a "video editor boilerplate" code somewhere (maybe open source?) that people are using as a starting point to create these great product and services all around the world. Anyone knows anything about that or want to share some thoughts on that? I am thinking about coding my own video SaaS but I rather save some time on the basic stuff and spend my energy on the new functionality instead.
