@Acaila
Did you compare the quality of the clips when you confirmed Didée's test? Because as we all know: higher PSNR does not necessarily mean better visual quality (that's why they used another method called JNI in a test by the german computer magazin c't. JNI should also consider the human visual system). Of course I know that Didée is here for a long time and I don't doubt that this matrix is great, but it just makes me wonder why.
@all
Some thoughts about different matrices:
1. you would no longer be able to use bframes (as you might know, Modulated and bframes don't mix). Do you really think you could achieve the same quality without bframes, by just using better fitting matrices? (I mean quality at low bitrates).
2. you would have to store all these matrices (the decoder has to know the matrix the encoder used). Then you would to set a flag which matrix is used. I don't know how modulated is implemented. But in the best case scenario, you would have to set a flag, everytime the matrix changes. In the worst case, you would need a flag for every frame that tells the decoder which matrix to use (well, worst case would be if the matrix would not be stored at a single point in the file, but would have to be there everytime it changes. But that is highly unlikely). Even in the best case, you would waste some bits. Say you have up to 256 different matrices. The flag would need 8Bit=1Byte to say which matrix to use.

You don't have to encode your credits separately. Just use the trim command in avisynth and filter this section more than the other. Then you can also use the xvid credits section and compress this part more than the others.
