I create slit scan images by placing moving images (animated layers or video) in a narrow comp, then repeating that comp across a wider comp (with RepeTile), and displacing each instance of the comp in time. This simulates a streak camera (or document scanner). These images can then be distorted (corner pinned) to simulate perspective and depth, which is the foundation of the "Stargate" look.

Key effects used:
- CC RepeTile
- Time Displacement
