Dealing with bad footage

I have some footage that is horribly blurred and has jagged edges. Is there a little chance to improve it?

Screenshot, 160kB

Quick and dirty:

No idea if it will work with actual animation. Don't expect too much from footage that originally was 180x120.

Try a different IVTC method, that looks like discard a field.

Thank you for your suggestions.

After seeing the screenshot I thought "Wow!" and tried it immediatly. It deals very well with the jagginess. Unfortunatly it increases the blurriness. This isn't that much remarkable with the frame I posted like it is with other scenes. Thanks for the effort. It gave me some ideas what to try, and realized that removing blurriness and jagginess while keeping the resolution are conflicting goals.

I bet that it was deinterlaced with discard field, but I can't change this. The screenshot was directly taken from the DVD, without additional deinterlacing or filtering. As I heard, it was made from a VHS-Capture

It was just a quick attempt to remove jagged lines (the biggest offender IMO) and to give you some starting point for further improvements. Anything more would be just guesswork with only the screenshot available. I think it is possible to make the footage tolerable (i.e. not hurting the eye with jagginess and stuff, not necessarily razor-sharp) if you're determined enough, though you'll probably need to treat each cut separately.

The AVISynth filters SangNom and TIsophote are supposed to help with jagged edges; you can find SangNom <a href="http://www.avisynth.org/warpenterprises/">here</a> and TIsophote <a href="http://bengal.missouri.edu/~kes25c/">here</a>.
