quantizer matrix

[Nielchiano]

Hi, This question might be better in an MPEG-group, but this is the closest I could get...

Can anyone explain me (or provide a link to a good explanation) what exactly those quantizers do? I know that they are verrrry important in defining the compression used, but why do they come in matrices?

Thx in advance,
Nielchiano

Here's a link but it's in German. Try a web translator german to english if you have trouble with the language.

Go to the following url and check out their forum section. There are various explainations and hints on quantizer matrices as well as GOP structures.

Not to mention, the KVCD TMPGenc templates are outstanding, if you have a compatible stand alone player (a list of compatible players is provided).
