By the way, to simulate a scene change, I cut the clip so it starts from the given frame and used VideoEnhancer. Comparison with full 40-frame clip here:

Very subtle but you can see it better at her hairline. The most moving part, the mouth, has very few visible differences for me. But when zoomed in with Photoshop you can see it.

Note that real results depend on the algorithm on how well VideoEnhancer recognizes a scene change.
