AviSynth / Gordian Knot problem

[walruss]

I use Gordian Knot to create an AviSynth script. But when I figured out the bitrate for the movie I want to convert, it ALWAYS ends up around 500mb. I have tried bitrates for both 700 and 1400mb and still get the 500mb.

I do exactly what is in this guide: http://www.doom9.org/index.html?/xvid.htm

What is wrong?

See if Q6.3 of the AutoGK FAQ helps:

Yes, it's AutoGK, but might apply for you as well. Anyway, often unexplained problems can be fixed by a complete uninstall/reinstall. Both GKnot and your XviD codec.

By the way, are you using GKnot all the way through or just taking the script it makes and then encoding it yourself in VDub(Mod)? You seem to be saying you're using it only for script creation. And maybe you can show us the script.

The AviSynth script has nothing to do with the bitrate of the final video. The bitrate set in the encoder determines that. The Xvid codec in your case.

Yes, but sometimes those scripts have an unneeded trim line in them that might truncate the video, thus giving him a smaller file than he asked for. He says the problem is the final size. That's directly related to bitrate, of course, but it's theoretically possible for it to both keep to the bitrate and to come out with a smaller size. GKnot determines the bitrate from the length as given by the D2V. If his script is for a shorter video, it'll come out undersized. I'm not claiming that's what's going on here, though. Just trying to cover all the bases.

I uninstalled xvid and installed the latest version but the result ended up 63 mb..

Do you have the log for the encode? And is the movie complete? The full length it's supposed to be? And it looks like utter garbage? For a full length movie, 63 MB is smaller than the audio alone in most cases. Are you sure you didn't encode the compression check?
