Unfilter crashes VDub

[iparout]

Hi there.

I am trying to use Unfilter.dll together with Lumaoff in order to decrease blockiness in the dark areas of the picture in my DivX 5 Pro encodes.

However I have just noticed that VDub crashes because of the Unfilter.dll.

The script I used is this :

VDub says "Avisynth open failure : Unrecognized exception !" line 44 (the Unfilter command)

Why does that happen ?

I am usig the Avisynth and VDub versions that came with GKnot 0.26 and also mpeg2dec3 beta 6.

Thanks in advance for any answers.

Try this:LoadPlugin("D:\AUDIO-~1\Video\Tools\GORDIA~1\mpeg2dec3.dll")
LoadPlugin("D:\AUDIO-~1\Video\Tools\GORDIA~1\UnFilter.dll")
mpeg2source("E:\Jennifer8\TEST.d2v",lumoff=-2)
crop(8,4,710,568) #ALWAYS USE EVEN NUMBERS FOR CROP
UnFilter(5,5)
BicubicResize(640,352,0,0.75) If this works, then the problem is simply that unfilter wants mod-2 or mod-4 resolutions, something that GKnot does not create as result from crop.

Nope, it didn't work unfortunately.

Same error, although now it's in line 5.

EDIT : I just installed the latest avisynth (2.07) and now the message says that "Unfilter only supports YUY2 and YV12 color formats".

I thought that the .d2v files were already YUY2 !?!

Are you sure you have the version of UnFilter that is intended for AviSynth2.07? It sounds like you have a version intended for AviSynth2.5a, and that won't work. (Also try 708/mod-4 as width in the crop)

Well, judging from THIS THREAD (http://forum.doom9.org/showthread.php?s=&threadid=28197&perpage=20&highlight=Unfilter&pagenumber=6), it looks like it's the appropriate version.

Both versions should now be in the zip. If you are not using the 2.5 alpha of Avisynth then you should be using the older one, which had no message mentioning YV12.

You can right click on the dll and choose version info to see, but you want the one in the UnFilter_Old folder in the zip.

Aha, I get it. I am using Avisynth 2.07 so I guess I shoild be using Unfilter_OLD. But won't that older version create that "greenish" effect that is shown in the Harry Poter screenshot you attached to your post ? Or am I misunderstanding something ?

No, it was only the "old new" version where I foolishly tried to also filter chroma, for YV12 only.

I'm guessing that all versions have round off truncation errors that slightly darken the clip. This was disasterous on chroma where it gave the green tint. But I don't dare change it for luma because folks like it to remove the dark macro blocks sometimes caused by lumi masking in Xvid (which may have a compensating rounding error). ;)

ok, I see.. Too bad that the Unifilter + Lumaoff combination didn't do much to remove the black blocks for me.. Maybe that's because I encode to DivX 5. :(

Oh well...
