Decomb seems to make unreadable AVIsynth files...

[ryouga]

So I set up an encode in GKnot, let it use Decomb, and then it wouldn't run through VDub. Wondered WTF was up... well, apparently Decomb causes this problem:

"Avisynth: caught an access violation at 0x1000bbbf, attempting to read from 0x07606000"

I turn off IVTC to comment this plugin's load out, and it works fine.. but of course no IVTC.

Do I go back to using GreedyHMA? Or has anyone else fixed this problem?

Hi-

The problem's almost certainly at your end. Probably a cropping problem (did you follow the "divisible by 4" rule?). But if you would include the problem .avs, it would help.

I'm quite sure it's at my end since no one else has the problem :)

Hi Again-

Well, nothing wrong with the crop. Put VobSub after the Resize and you'll be OK. Don't ask me why it has to be that way (because I don't know).

And I guess you decided to leave the black bars at the top of the opening song and along the left side of the end credits.

And why are you trimming the Previews? They're some of the best parts.

And you might try this:

Telecide(Guide=1,Gthresh=50,Chroma=True,Threshold=30)
Decimate(Cycle=5)

[ryouga]

I trim the Previews because they are also some of the most motion-heavy parts of the episode; they munch a LOT of bits. And I leave the bars because they aren't that big a deal, and I'm not sure how to remove them and still leave that part there for the rest of the video.

Thanks - that option seems to have done it for me. VobSub has no problem being before resize though - is there some reason to put it there?

Err, it only seems to do it if I don't crop it at all. Weird. I'm just knocking 8 pixels off left-right, though...

[ryouga]

Gah, I'm not getting this. If I don't crop at all, it works perfectly. I can get up to two pixels cropped off the right side before it dies, and I can crop as much off the top or bottom as I want. It's weird...

Edit: HA! It _IS_ VS screwing up. It has to be put in before cropping, or after resizing.
