Green band when using kerneldeinterlace (GK 0.33.1)

[ChAoS Overlord]

Since I switched to the new Gordian Knot, I get these horrible green banding on the right of my screen every time I try to use the kerneldeinterlacer. What is the cause of this?

I've done a clean install of windows and installed just the Gordian Knot 0.33.1 package.

Hi-

You're probably not cropping the height in Mod4. Either crop Mod4, or move the KernelDeinterlace line before the Crop line. Read this (http://www.avisynth.org/Crop) and this. (http://www.avisynth.org/DataStorageInAviSynth) The information you want is for the YV12 colorspace. If that doesn't fix it, then please post the .avs (with all lines beginning with "#" removed).

Same problem here with Gknot 0.33.1 kernel deinterlace + XviD 1.0.3.

Always cropped mod4 with previous Gknot versions and didn't noticied any problems untill this Gknot 0.33. Probably 0.33.2 still have the problem, will check it later.

I back to 0.32 beta and XviD 1.0.2 and the video comes out perfect.

Will try to find the AVS (when I had it I was not allowed to post untill 5 days have passed from registration...)

My pc has crashed atm, so I can't reproduce it right now... Will have to wait a few weeks before it's back up again...

Here's an example that gives me these problems

LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\dgdecode.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\decomb.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\KernelDeInt.dll")
LoadPlugin("C:\PROGRA~1\GORDIA~1\AviSynthPlugins\UnDot.dll")
mpeg2source("F:\Rip\Interviews.d2v")
crop(10,4,700,568)
KernelDeInt(order=1,sharp=true)
LanczosResize(576,320)
Undot()


Gordian Knot hands it to me this way. So that would be a bug, no? They should move the deinterlacing before the cropping or something?

You cropped Mod4, alright; 4 from the top, and 4 from the bottom, following all the rules. Looks OK to me. Time to do some diagnostics.

What happens when you put the crop after the deinterlace? Does that fix it or not? Are you sure it's TFF? What happens when you change the field order to Order=0? Nothing, except maybe messing up the deinterlacer? What happens when you remove Undot (put a "#" in front of it? Anything? What happens when you comment out everything (crop, resize, deinterlace, and undot). Is it even OK to begin with? If so, put things back one by one to see where the problem occurs.

When things like this happen, you have to do things like rearranging the lines in the script, or changing things around to try and pinpoint the reason for the problem. After each change, save it, open it in VDubMod and scroll around to see if it's been fixed or not.

I put kerneldeint in front of the cropping and the problems were gone...

I had similar color problems (weird ghosting) with TomsMoComp. Putting it before cropping fixed it too.

So, any ways to avoid the lines without editing manually the script each time? I've done a movie about 5 times now, with custom cropping, auto cropping, resizing at 32x16, at 8x8 etc. and still get the problem...can anyone help out?

Use the advanced save avs window, and save the script as an ini file (as prompted). This way, every time you want to use kerneldeint, all you have to do is load the template :)

...or use latest version of GK...
