How to arrange pictures/videos symmetrically in Adobe After Effects or Adobe Premiere?

Question

Adobe After Effects

So, for example, I want to place 12 pictures / videos on one screen, so that there is the same distance from the edges of the screen to the edge of the first picture / video and from the edge of the pictures / video to the edge of the pictures / video. That is, 4 rows and 4 columns is obtained. I usually do the math myself with a calculator. But is there any more convenient and faster way?

Answer 1

The easiest way: Find the Replicate effect in the effects and divide the picture into as many parts as you want.
