dot crawl

Postby Minion » Sun May 13, 2007 6:04 pm

working with the EoE r1.
tcomb and dedot don't seem to be cleaning up the dot crawl as well as i'd like. most noticeable in asuka's big angel fight.

here's a small clip without dedot, tcomb, ect.

my current script (besides the cropping and boarders)
Telecide(order=1,post=2,blend=true,vthresh=30,back=1)
Decimate(cycle=5,mode=3,quality=3)

not included in the export shown above

oof, that's ugly
Tcomb(mode=2,fthreshl=12, othreshl=19) gets the job done, but at the expense of detail.
I think that fthreshl=9,othershl=4 was a bit better (and got rid of most of the dot crawl)

I'm using tcomb v2.0 beta 2
from the readme:
othreshL/othreshC - (original pixel correlation thresholds)

One of the things TComb checks for is correlation between original pixel values from every
other field of the same parity. Due to the oscillation period, these values should be equal
or very similar in static areas containing dot crawl or rainbowing. If the pixel values
differ by less than othreshL (for luma) or othreshC (for chroma) then the pixels are considered
to be correlated. Larger values will allow more filtering (will be more effective at removing
rainbowing/dotcrawl), but will also create more artifacts. Smaller values will produce less
artifacts, but will be less effective in removing rainbowing/dotcrawl. A good range of values
is between 4 and 8.

default: othreshL -> 5 (int)
othreshC -> 6

similar explaination for fthreshl and fthreshc

nope, no idea whatsoever. I/you could have been typing it incorrectly
that's about the only thing I can think about.

you might want to try looking to see if there are any other required plugins (like a specific version of masktools)
if you don't know what version of avisynth you have you could try installing the latest version
