transition on only one clip Final Cut Pro
Basically I've started doing drum covers and filming them, 2 cameras one showing the arms and what's going on on the kit above and then one focusing on the feet. So what I want is for the whole screen filled with the main above kit video and then around 25% of the screen will have the feet video. I've got all of this down, but the feet video doesn't start from the beginning, and I want a transition on it when it comes in. The issue I have is that the whole screen (both videos) do this transition, not just the small video, is there a way to do this? thanks!
