Lloyd Alvarez has just released a super handy DV Rebel tool called Magnum—The Edit Detector. It's a script for After Effects CS3 that automatically finds edits in a layer by analyzing the imagery. It then either marks the edits with layer markers or slices the layer at the cut points.
The latter of course is a perfect first step to a DV Rebel grading workflow. Now you can easily get your cut into After Effects without worrying about EDLs or XML or whatever.
This process is known as "scene detection" in high-end grading systems, and now you've got in in After Effects. And it's free-as-in-beer. As in, Lloyd, I owe you one.
