As someone who has also worked on an in-browser video editor before, I do tip my hat to the developers working on Clipchamp. I think it's one of the better implemented products in this space considering that the memory-intensive process of encoding videos has not traditionally scaled very well into the browser. That being said, I'll probably still be sticking to something like iMovie or Resolve for more basic video editing since native NLEs are still way more performant overall (and they're free to use).
