TomsMoComp + Gknot problem

[rowland]

Using Gknot 28.7.2 and the lastest Gknot code pack.

Trying either a compressibility check, preview or encode with TomsMoComp I get the following dialog box:

Avisynth open failure:
TomsMoComp: Horizontal pixels must divide by 4

And it makes a reference to the following line in the .avs file:

TomsMoComp(1,5,1)

(I'm sure it doesn't actually interfere but it also makes no diff if I select Divx or Xvid)

The res I'm trying to use is 480 x 256 (both divisible entirely by 4 without remainders) and I've tried other res without luck. What am I doing wrong?

Thanks to anyone who can help :)

A known issue. Horizontal pixels must be divisable by 4 BEFORE resizing.
So check your resolution tab and make sure that cropping (before resize!) meets the above constraints.

btw, are you sure you have an interlaced source? Sometimes a source might appear interlaced, but it's just out of order fields. This can easily be corrected with e.g. Telecide(order=1,post=0,guide=2)

Dvd2Avi claims PAL Interlaced on preview of source mpv file.

Manually adjusting the auto-crop values fixed it, thanks for the tip Piscator...

...now I can get on and test this filter for myself :)

DVD2Avi can claim what it wants, but it's probably not interlaced. DVD2Avi is known to make false interlaced claims when fields are shifted.

Search through the guides section. There is a really nice guide somewhere that shows how an interlaced source looks like. Note that you have to do the check yourself while skipping through frames in the preview: interlaced means you see a weird combing artefact. If you don't see that the source isn't interlaced. Even if you see that, the source may still not be interlaced but simply field shifted. Try the telecide filter I posted above. Note that deinterlace/decombing filters severly damage the quality of your result, especially when wrongly applied.

If your source is a DVD, I'm 99.9% sure it's progressive and not interlaced. TV captures are, of course, a different story.
