Q: what is a nice thing you have learned while editing video?
A: many things. here's one. The program i'm using doesn't have enough keyboard shortcuts, which is really problematic for working fast. But maybe a year after i had been using it and doing videos every day, i found an insane work around.  On a mac, there is a help menu, which seems to have access to EVERY menu command, and it is searchable. So if i type ⌘? and then the first 2 (or 3) letters of the menu command, then hit enter, it works. Sure, it's like 8 keystrokes, but once you get fast at it, it is almost as good as having a key-command. Finding a keyboard shortcut for something that doesn't have a keyboard shortcut is a huge victory if you are trying to make content as fast as humanly possible
