| Xvid Inter and Intra Matrices |
=================================

As of xvidenc version 5.2, the package includes Xvid Inter and
Intra matrix files. The package includes the Jawor Quantization
Matrices which provide excellent compression and quality.

I've included two different types of Inter and Intra Quantization
Matrices. First one, located in "matrices/Jawor1CD" are for
low bitrate encodes where one wants to fit a whole movie on 1 CD.
Second one, located in "matrices/Jawor2CD" are meant for
higher bitrate encodes where one want to fit the movie on 2 CDs.
They preserve a bit more picture detail than the first set of matrices.

You can load the matrix files with the help of the 'xvidenc' script
if you choose for the 'Advanced Options' option when asked and come
to the point where the script asks you if you want to load custom 
intra/inter matrix files. Answer 'y' and provide the full path
to both matrix files. I suggest you copy the matrix files you want
to use to your home directory or to your 'Documents' directory.

Example of loading matrix files with xvidenc:

Provide the Intra Matrix file: /home/your_username/xvid_intra_matrix_1cd
Provide the Inter Matrix file: /home/your_username/xvid_inter_matrix_1cd


====================================================================


By default, when you run the 'install' script of the package, it
will install all matrix files in these directories:

/usr/local/share/doc/xvidenc-<version>/matrices/Jawor1CD
/usr/local/share/doc/xvidenc-<version>/matrices/Jawor2CD

or if you have obtained the RPM or Slackware package, then
the matrix files will be in:

/usr/share/doc/xvidenc-<version>/matrices/Jawor1CD
/usr/share/doc/xvidenc-<version>/matrices/Jawor2CD

or

/usr/share/doc/packages/xvidenc-<version>/matrices/Jawor1CD
/usr/share/doc/packages/xvidenc-<version>/matrices/Jawor2CD

or for Slackware

/usr/local/share/xvidenc/matrices/Jawor1CD
/usr/local/share/xvidenc/matrices/Jawor2CD
