Hi guys. I'm doing a restoration project and I could use some help.

The source material appears to have all the chroma information shifted lower down the frame.

My source (enlarged):

Same scene from a good source:

The source I'm using contains deleted scenes that are not available anywhere else, so I'm stuck with it.

Can anyone tell me a good way I can move all the chroma back up where it belongs?

FYI: I'm very familiar with VirtualDub, and basically familiar with AviSynth.

Also, any other tips on making this look better in general would be very welcome. :)

There's an AviSynth filter called ChromaShift which can apply an vertical chroma shift (it can also apply a horizontal shift to U and V separately, if required).

It's a difficult source to deal with. Maybe you could try some deblocking, then add some false grain.
