Gradual Frame / AR Expansion (recovery)

[Danette]

This may be hopeless without tediously changing each involved frame, but I thought I’d ask anyway. I’m assuming that this can be addressed utilizing Avisynth. Any other suggestions are welcome.

The sample can be found here: https://www.mediafire.com/file/zzzosa6oikcljve/Sample.mkv/file

As you will see, this is an example of a common adulteration of credits. I would like to see if anyone has an idea about how to crop each frame automatically (presumably over a fixed number of frames) that has the lower part of the frame expanding, while simultaneously expanding (recovering) the upper, original, part of the frame, so that the credits part of the screen appears to be unchanged in it’s original AR.

Hopefully, this will make sense when you view the sample.

If it's static like example, then do this (after deinterlacing):

FreezeFrame(26,75,25)

I've got an unreleased tracking plugin that will fix this a bit more naturally than freezing a frame. It's not entirely automatic and it could use a longer version of the video so there's more video available to composite in and cover up the graphics.

Could it track logos? :)

Probably... what have you got that needs tracking? It'd be helpful to try it out on other people's videos to refine it before release (which I've been planning to do for some time).

Don't have anything at hand but it could be emulated, from examples posted at this forum: text slowly moving around frame, or it stays static for ~10s then jumps at some random location.

I can provide as long a video as Mediafire will allow. How long would you like?

Last time I looked, my [Free] MediaFire account limit was at 52GB [I think, I think it grows the longer you have account].
[I use a couple of hundred MB of that limit].

Jumping will make things slow since it'll have to search the whole frame each time but it should work.

Thing is I can't really remember where I got to with development so I'm not sure what still needs finishing off...
