another show, another problem. not even sure what this is called so i'll try to just explain it.

sample (http://www.mediafire.com/?4f34gu5x35v3zt8) (would have made a shorter sample but my vob splitter isn't acting right so i chose the smallest chapter)

if i understand what dot crawl is, then i think the initial title has dot crawl on the letters. is that right? BUT, as you can see, after the episode starts the black lines dance around throughout the whole thing. is this a variance of dot crawl or something different? i tried using dedot() and checkmate() but it didn't help the lines. should i be changing the parameters of checkmate or dedot to solve this?

if i know the correct term for my problem maybe i can find a solution. if someone knows how to solve this i would be pleased because while i can clean up the image, the black lines aren't fixed.

thanks again to whoever can help me.

any advice? would really love to get these episodes encoded. i have pretty good looking results except for the moving outlines.

is there no cure for this problem or is the forum just not that active as of lately? i would love to encode the four volumes i have of this show (and eventually the fifth volume once i get it) but i don't want to have to re-encode them later if this can actually be solved.

I suggest you try the AAA (http://avisynth.org/mediawiki/AAA) filter.
Its purpose is to perform antialiasing on animation footage. I recently had the same problem with some Disney footage, there was lots of dot crawling on the contours. By using AAA() I got rid of the most of the dot crawl.

You may also want to try out some denoising on that footage, such as the comprehensive MCTemporalDenoise. The presets are quite good, MCTemporalDenoise(settings="medium") or the low preset could clean that footage very well (if that's what you want). The downside to this is that processing will be very slow, so mostly I'm just satisified with using AAA. :)

Edit: AnimeIVTC should be very useful for deinterlacing.
I did some quick tests and this seems to work ok:

checkmate()

animeivtc(mode=4, aa=4, omode=1)

aaa()

I'm not sure if the mode in animeivtc is correct but it seems to work ok.
