I'm trying to do something similar to what was done in The Hulk or Rules of Attraction.
I'm doing this in 16:9
I have two video streams cropped down to 355 x 480 each (the remainder being an extra 10 pixels to be the separating line).

The only problem is I can't figure out how to move the actual video file so they're on opposite ends of the display and not overlap.

Please let me know how to do this,
Thanks a lot
