You_Too: I agree. That's what I was trying to say in my previous post.
However, I was also trying to point out that it doesn't do anything sophisticated. It looks like a very simple algorithm was put into use.
Edit: Here's a challenge!
1. Look at the image of Leia in my previous post and find the corresponding frame in GOUT (I think it's 58995 in PAL GOUT). Also, note that it occurs at a shot/scene-change. Let's call this ``curr''.
2. Take the preceding frame (it contains a shot of Darth Vader on the left and the side of Leia's head on the right) and the successive frame. We'll call these ``prev'' and ``next'', respectively.
3. Jump 4-5 frames ahead (just enough for the blending to disappear). 58999 in PAL GOUT is probably a good candidate. It shouldn't be too different from the frame in #1. Let's call this ``temp''.
4. Using Overlay (or something similar) with ``prev'', and possibly ``next'', try to make ``temp'' look as much as possible like ``curr''.
Note: You probably only have to work in luma for this to work.
