gknot file size problem

[alc101ma]

I am using GK to encode a movie with DivX5. I set a 2 cd total size of 1410MB. It says I should get about 1282MB of movie data and estimates 119MB for 160kbps sound. So I encode the movie. When I look at the result the file size is only 632MB. I figured maybe I goofed somewhere as I did quit and change some settings half way through once. So I start from scatch and create a new DVD2AVI project and encode again. The result is another small file. The movie is pretty dark so it came out looking ok, actually. I've encoded about 5 or 6 movies so far and this is the first time I've had this problem. I think I heard about someone having this problem before. Any ideas, help, or suggestions?

There are two possible explanations for something like this.

1. The maximum possible quality for that movie has been reached. You can check this be reading the file called analyse.log which divx5 creates durring the second pass. If all frames are encoded with quantizer 2, the quality is maxed out. I have posted a perl script for checking this, in this thread http://forum.digital-digest.com/show...&threadid=9446

2. You divx5 installation has become corrupted, this usually happens if you install an app that installs divx4, like GKnot0.21.

thanks

Thanks. Yes it says 2 for the quantizer. I did some tweaking though, and I noticed that if I manually set a higher bit rate... I can make the file size larger. It is still not encoded at this bit rate, but it does make the video bigger and there seems to be a very slight increase in video quality. It is very hard, though, to determine the proper final file size doing this.

Oh, if I don't use the bi-directional encoding option, what will this do? I forget, does using that option selectively take out some video info and make the file smaller?
