Need help fixing dot crawl and rainbowing

[Scyrous]

Hi there!

I'm working on a script for the anime ''Yu-Gi-Oh: Duel Monsters''. The NTSC source DVDs contain lots of dot crawling and rainbowing issues that I'd like to eliminate.

I've got an encoded sample by someone called DarkDream, which looks superb compared to the original DVDs. I'm using his encodes as a ''goal'' for my own encodes, in terms of quality.

And yes, I already asked DarkDream about the script he used. No reply yet and I'm likely not going to get one. :P

- Samples -

DarkDream (15mb): https://mega.nz/#!lMUzhQDB!Fql8JVwll...JaEiHx0VyZKoEk

DVD source sample (45mb): https://mega.nz/#!lA8lRDQS!4MtZwHQ9n...40TpzTumGw602U

This is my script so far:

checkmate(thr=20, max=1, tthr2=0).checkmate(thr=10, max=1, tthr2=0)
Bifrost(interlaced=true)
tfm(order=-1).tdecimate(mode=1,hybrid=0)
Crop(22, 6, -4, -4)
Spline36Resize(640, 480)
Santiag() #Optional
Deen("c3d",0,3,2)
FastLineDarkenMOD(strength=40)
LimitedSharpenFaster(ss_x=2.0, ss_y=2.0, strength=30, overshoot=0, undershoot=0, soft=0, edgemode=0)

It looks somewhat good but the dot crawl and de-rainbow filter need a lot of tweaking. Footage is also a lot less sharper than the DarkDream encode for some reason, even when the strength parameter of the sharpener filter is bumped a lot. In fact, any help regarding the filters in my script would help. Better alternatives, parameters, etc.

I figured calling the checkmate filter twice would help out but I'm most likely wrong. Seems to cause more artifacts to appear.


Thanks in advance!
