i decided i'll ask on here before i spend half the day trying to figure it out by myself..

imagine this, its easy: the screen vertically divided into lets say 6 columns and each one is a different still shot. (perhaps the way the major characters are sometimes shown in movie trailers.. or in my case, the way i will introduce the members of a band).
but all do not appear at once. the screen is black and maybe the far right appears first, then the second from the left, then one of the middle two, etc.. until the screen is full.

how do i crop and position these images?
thanks

Its easy. Layer the clips in V1, V2, etc.

Then, go to the motion settings tab for each, and adjust the crop sliders for left and right

To make them appear separately, just start the clips at different points in the timeline.
