Clean up dodgy anime source?

[Decane]

Hey all.

I got a rather old anime dvd which was recorded from what looks like a ntsc VHS and then converted to PAL-B. Naturally the quality is rather noisy.

What is the best way to clean an anime style movie. There's large areas of consistant colour. (or at least it should be consistant :) ).

This is the first time i've worked with a dirty source so any help would be appriciated.

When a source has been converted from NTSC to PAL (badly) I usually recommend telecide(blend=false).SpatialSmootherMMX(...) (Take the numbers from GKnot, I don't remember them right now). Now, for an anime that has a lot of areas with same color, I think Convolution3d(preset="animeLQ") can be very useful. Put it after telecide() but before any other smoothing. Normally temporal smoothing should be avoided with NTSC2PAL conversions as it will add to the ghosting effects, but it seems that C3D is quite good at avoiding that in most cases, and anime is slightly different from normal FILM as it is very possible (and even recommended) to do heavy filtering to get rid of encoding artifacts. Right now I'm doing some tests myself with an anime DVD PAL to see what can be useful in these cases. (@manono: I'll get back to you about that during next week :) )

Oh yes, a hint: don't ask 'what's best?' That depends too much on the source and everybody isn't as nice as I am. (http://forum.doom9.org/forum-rules.htm)
