Switch not making clips?

Why can't I make clips for Paladins and Fortnite?

Is there any method of making clips (please don't use anything with a cell phone now)

Somehow it doesn't work with shooter games. That should probably improve the performance.

This function has been deactivated in certain games to improve performance. There's currently no way around this.

So you can either film it or record the signal with a CaptureCard or similar.
