Copying area inside frame (frame by frame) - how with avisynth?

[_Donnie]

Dear specialists,

I would like to edit a video and copy a small area inside a frame to another area. For every frame.
How could this be done effectively with avisynth?

Example picture attached

The marked area below the red logo should cover the logo completely in every frame.
20 seconds example movie attached also

Scripting help very appreciated...
Thanks.

Use Crop() to make a copy of the blue area. Then Overlay() that clip over the logo.

patch = Crop(x, y, width, height)
Overlay(last, patch, x=?, y=?)

Ha, so easy. Thanks a lot.
Worked for me

patch = Crop(84, 108, 92, 62)
Overlay(last, patch, x=84, y=46)

Simply:

DoomDelogo(84, 46, 92, 62)

Yes, inpainting works very well when the area around the logo is flatly colored.
