I'll try to explain this as best as i can. I am having a problem with a composition in after effects. I'm trying to get a composition of a phone to move toward another part of the screen. When i do this however, the layers inside the phone composition lagg behind it slightly; leaving part of them sticking out of the side of the phone.
Here's a pic to help you understand:
The screen is a layer inside the composition of the phone, and the phone is moving from left to right.
