how to process this kind of video

[hxhxd]

Hello, I have a clip that seems to be like blended source. But I'm not sure about it.

This is the sample clip.

I want to restore the original frame. How should I do?

Thanks very much!

Like you say, it appears to be blended. In which case you can't.

srestore() can fix the blending and then TDecimate() can remove the duplicate frames.
