Remove vertical scratch in this animation title

Is it at all possible to reduce the scratch in this video clip? The highest rez available for the file is 1080P, if that helps.

Scratches are almost impossible to eliminate. If they were static, you could use a delogo filter, but unfortunately they tend to wander back and forth. This is true of your scratch as well.

There is a descratch filter for AVISynth, and you could give it a try, but I've never had any luck with it.

I do a lot of film restoration and the only way I know to get rid of scratches must be done during the transfer, using a "wet gate" transfer. However, since you don't have access to the film, that won't do you any good.

Since the line seems to have the same color and is moving inpainting might not be needed.
A masked Despot/Descrath filter might work.
Upload a sample to somewhere where it does not get reencoded and folks probably come up with different ways to remove that line.
