Here's an example screenshot from my current cleanup process.
- Top left is original video;
- Bottom left is cleaned up using the stretch-SpatialSoften-squash technique (plus a light sharpen);
- Bottom right is the difference between the two (highly exaggerated).

You can see the lines on the singer's jumper and skirt (especially low down, in the shade), and also on the back of the music folder sitting on the stand. The stripes seem to be 1 or 2 pixels wide, and repeat *mostly* every 8 pixels, although sometimes they seem to be every 4 pixels.
As this stuff is all concert footage, I'm mainly concerned with preserving the performers' facial details, and avoiding any artifacts that distract from the performance.
