What Does the Matrix Setting in TMPGenc Do?

[Los11]

And Which Is The Best Configuration.

Somewhat complicated question.

The matrix setting is the defined quantization matrix used by the MPEG encoder. A quantization matrix is basically what controls how the different frequencies of image data are truncated during frame processing. The particular details can get pretty deep (DCT-2s and colorspaces and what not).

To save some time, let me recommend using the default MPEG standard for most live action film that has a good mix of light and dark colors. For bright animated films, uniform matrices are generally a good idea (I believe TmpgEnc has a nice setting in there for it already) - the idea being that animation generally has lots of chunks of single color blots and not too many color gradients. If you're encoding particulalry dark films or black and white films, I find that increasing the numbers towards the lower righthand corner (ie the high frequencies) can give improvements, however that is likely just film dependent.

Or perhaps I'm just wrong.

No, that's pretty much right.
