Which comparison should I use?

What do you want to do?	Tool to use
I want to see which of two takes has better delivery, framing, or movement.	Duel: watch two videos side by side. The screen that opens is called Which one stays?
I want to compare the files’ duration, resolution, size, or codec.	Copy differences: compare file details side by side. The screen that opens is called Which one is more complete?
I haven’t found other takes to compare yet.	Use G to search for other takes or similar scenes.

Similar takes and exact copies are different things. Different attempts at the same subject may look similar but they’re separate videos. The Any other takes of this? search in the G menu helps you find similar takes; to see exact copies, use the copy badge and the V key.
