rainbow glitch while encoding in nandub

[Norco]

in the screenshot included, while encoding in nandub i get these rainbow line thingies or lines in the video and not sure why, i encoded again and they disappear but might be found on another frame instead.. any clue whats causing this?

I've never seen such error before. It could be a shit frame, although these don't look so or a freeze frame or you're using unstable version of ffdshow directshow filter (or any other non DivX 3.11 directshow filter) and so on... Give us more information about the options you used in NanDub.

well this how i been doing it.. first i make a avs file

LoadPlugin("C:\Documents and Settings\Dex\Desktop\encoding stuff\GordianKnot\mpeg2dec.dll")
LoadPlugin("C:\Documents and Settings\Dex\Desktop\encoding stuff\GordianKnot\decomb.dll")
mpeg2source("C:\Documents and Settings\Dex\Desktop\encoding stuff\d2vs\englishblock251.d2v")
crop(8,0,704,480)
telecide()
decimate(cycle=5, mode=2)
BicubicResize(512,384,1/3,1/3)

then i load that in virtual dub and load up smartsmoother hiq and encode with huffy.. which shows some of those rainbow frames.. after thats done i then load it up in nandub and encode with these settings ill include the vcf file from nandub and more of those rainbow frames may appear but worse then when i made the huffy avi file.. so i dunno wtf is going on hehe its peeing me off :devil:

Why do you convert to huffy ? Why don't use the smartsmoother or similiar plugin for avisynth ? You'll save a lot of time and the quality wont suffer ;) You could try the Convolution3D plugin, which removes the noise e.g. film grain very well.

and try something like this:

LoadPlugin("C:\Documents and Settings\Dex\Desktop\encoding stuff\GordianKnot\mpeg2dec.dll")
LoadPlugin("C:\Documents and Settings\Dex\Desktop\encoding stuff\GordianKnot\decomb.dll")
LoadPlugin("Convolution3D.dll")
mpeg2source("C:\Documents and Settings\Dex\Desktop\encoding stuff\d2vs\englishblock251.d2v")
crop(8,0,704,480)
telecide()
decimate(cycle=5, mode=2)
BicubicResize(512,384,1/3,1/3)
Convolution3d(0,8,8,8,8,3,0)

then, just load the avs script in Nandub and encode.

Hope I could help you ;)

instead of using smart smoother in nandub.. make the huffy first, because when doing straight in nandub the passes go like 4 fps... so instead make huffy file once which is just 1 pass at 4 fps and when load the avi into nandub the passes go at 30+ fps which saves a lot of time.. and i been posting for a friend who can't post on doom9 yet.. so i'll see if my friend will want to try c3d

like i can encode on a p200 :p
