Scrambled Video Problem

[FoolThemAll]

Sorry about the original post.

I'm in the process of trying to rip and encode The Matrix. Everything's fine, up to and including the first pass with Nandub (I'm using Gordian Knot). But when I use Nandub to create an avi, something goes wrong. At key points in the movie. You know when Neo and Trinity are on top of that roof, and an agent takes over the guy in the chopper? Neo fires at him, missing every shot, then "moves like they do" as the agent fires back at him, using a painful-looking bending backwards in slow motion technique?

Anyways, at this point and several others, the video is scrambled. Yeah, just like the scrambling that would happen with NES games, the kind you tried to fix by blowing into the cartriges.

And actually, when I try to play Jesmaster's "Pizza Matrix" video, the same thing happens. Except that the scrambling's all throughout the video, and apparently forces the video to close (I get an error message).

So, any idea what I'm doing wrong?

I searched the site and the faq and found no mention of this problem. Unless I'm an idiot and searched in the wrong places somehow. Please, have mercy on me if that's the case.

Hi-

What happens when you open the scrambled video in VDubMod or Nandub and scroll to the place that's scrambled? Is it screwy looking in VDubMod also? If it looks normal in there, it's some kind of a playback or decoder problem.

Other than that, please post the log file and the .avs (without the lines beginning with "#").

Thanks for your fast reply.

Yes, it's still scrambled in both VDub and Nandub.

The AVS:

LoadPlugin("C:\PROGRA~1\GORDIA~1\mpeg2dec.dll")
mpeg2source("C:\THE_MATRIX_16X9LB_N_AMERICA\VIDEO_TS\matrix.d2v")
crop(0,61,720,356)
BicubicResize(608,240,0,0.75)

What kind of file is the log file, what extension does it have, and what might the name look like?

Hi-

You're not using an up-to-date GKnot if it gave you those crop values. Try making all the crop values even numbers and report back.

Read this (http://www.avisynth.org/index.php?page=DataStorageInAviSynth) for more information about cropping within the various color spaces.

If that doesn't fix it, the log file is named something like <movie>_Gknot.log (thanks jggimi).

I downloaded Gordian Knot at some point in August from doom9.org. I changed the 61 to a 60 and will see how that works.

It doesn't look like the avs lists the various color space crop values (or whatever you'd call them), it just lists that one line for cropping. So I'm not sure how to use this link.

If that doesn't fix it, the log file is named something like <movie>_Gknot.log (thanks jggimi).

I can't seem to find this. Where would it be saved by default?

And there's something I neglected to mention that may be pivotal.

VirtualDub has detected a potential problem:

You are trying to compress with a hacked compression driver. This may cause VirtualDub to crash or to act unexpectedly. Proceed at your own risk.

Yeah, the more I think about it, the more I go, "D'OH!"

But it doesn't make sense to me. I got divx directly from the official site.

Hi-

Just make sure you always crop even numbers and you'll be OK. But if you're using AviSynth 2.52, and your source is interlaced, then you crop the height (top plus bottom crop) in multiples of 4. If you're using AviSynth 2.5x, then you're in YV12. If you're using 2.08, you're in YUY2.

To find out which version of AviSynth you're using, make an .avs entitled Version.avs. Inside have just this line:

Version()

Open it in VDubMod and it will tell you. If you're still using 2.08, then you should definitely upgrade your GKnot (Rip Pack and Codec Pack). If nothing else, your encoding speed will improve dramatically.

You are trying to compress with a hacked compression driver.

You can ignore that. That's the message you get when using DivX 3.11.

Where would it be saved by default?

In the same folder as the movie. Supposed to be, anyway. Perhaps you have "Delete Intermediate Files" checked in the Encoding Control Panel.

[FoolThemAll]

Still scrambled.

I created that avs like you said; turns out it's version 2.07. Where would I get the mentioned upgrades? This site (http://gknot.doom9.org/) lists exactly the files I downloaded in August.

Perhaps you have "Delete Intermediate Files" checked in the Encoding Control Panel.

Encoding Control Panel of which program?

Thanks much for your help so far. It's sorta off-topic, perhaps even off-site, but might my inability to play a matrix music video have something to do with all of this? Did my computer break the matrix? Is it The One?

Hi-

Yes, your version is way out of date. But first:

Encoding Control Panel of which program?

Of GKnot. I forget what it's called in your version, and I don't feel like installing an older version to find out. In the middle of this page (http://www.doom9.org/gknot-divx5.htm) is a picture from an old version showing "Delete Intermediate Files".

Where would I get the mentioned upgrades?

At the top of this page (http://www.doom9.org/gknot-main3.htm) are direct links to the Rippack and Codec pack.

But back to the scrambled picture. Maybe the decrypting process went bad. Open the .d2v in GKnot and scroll to the place where the finished .avi looks bad. Does it also look bad in the .d2v picture? If not, open the .avs in NanDub and go to the place where it looks bad in the finished product. Does it look bad there? If not, and since your .avs is now fixed, I can only conclude that it's the usual DivX 3.11 "shit". It looks like really nasty big colored blocks and/or smears that some people get when using that codec. You can put on anti-shit. You can do that through the newer versions of GKnot. I don't know about the version you have, though. Or you can use another codec, such as DivX5 or XviD. They don't have the problem.

[FoolThemAll]

That's exactly what I'm experiencing, 3.11 "shit". As far as I can tell, my version doesn't have Anti-Shit. Since I'm impatient, I'm going to try divx 5 instead. Thank you very much, I'll report back as soon as I get a new avi.

[FoolThemAll]

It worked. Beautifully.

Thank you for all your help.

Hi FTA-

Good one. I'm glad you got it sorted out, and now have a successful movie under your belt. And thanks for reporting back. By the way, if you still want to use DivX 3.11, just upgrade your GKnot and follow the Guide (http://www.doom9.org/gknot-main2.htm) until you've got it wired. At the bottom of this page (http://www.doom9.org/gknot-divx3.htm) is a picture of the "anti-shit" checkbox that should prevent the problem in the future. It does slow the encoding process, though.
