Need filtering suggestions for difficult scenes

[whee32afk]

Hi, I've been working with some anime sources lately, and need some guidance on what filters/methods to use on certain frames with heavy blocking and noise.

I've tried undot, convolution3d, pixiedust, fft3dfilter, but they can't improve the image very well.

See attached pics for some examples.

There is a lot of residual interlacing from a deinterlacer, so I suspect the extra bit budget for that is at least partially responsible for the blocking. It's just a bad encoding. Where'd you get it?

R2 source for the Cagliostro movie. It's a very noisy source. Film grain all over the place. Here's the sample of the avs script from Yatta.

Mpeg2Source("D:\WoHSVCD\Project\Cagliostro\cagliostro.d2v")
FieldHint(ovr="D:\WoHSVCD\Project\Cagliostro\cagliostro.d2v.fh.txt")
.... (trimming & freeze frames)
Decimate(cycle=5,quality=3,ovr="D:\WoHSVCD\Project\Cagliostro\cagliostro.d2v.dec.txt")
.... (post decimate processing, undot, pixiedust, convolution3d, dup, etc)

I've also stepped through the d2v project (dgmpegdec147b4) at those scenes for comparison. It seems like fieldhint is choosing some bad fields for combining into frames. Some motion will be lost if i discard those reconstructed frames, though.

Any suggestions to clean up the artifacts and blocking at least?

Try preprocessing with fft3dfilter(interlaced=true), and playing around with the various sigma values. That might help it choose better frames in matching. (Doubly so if any noise was introduced post-telecine.)

Bump.

Any suggestions on what filters to try out for reducing/removing the heavy blocking & artifacts?
