They're built into HCEnc (and also found in Matrix collections that are floating around). Or:

Code:
Fox 1:

        08 08 09 11 13 13 14 17
	08 08 11 12 13 14 17 18

	13 13 14 17 19 23 28 34
	13 14 17 19 23 28 34 41

	08 08 08 09 09 09 09 10

	09 10 10 10 10 11 11 11
	10 10 10 10 11 11 11 11

Fox 2 (Slightly different from the version HCEnc uses, but very comparable):

        08 08 09 11 13 13 14 17
	08 08 11 12 13 14 17 18
	09 11 13 13 14 17 17 19

	13 13 14 16 17 20 24 29
	13 13 14 17 19 23 28 34
	13 14 17 19 23 28 34 41

	08 08 09 09 10 10 11 11
	08 09 09 10 10 11 11 12
	09 09 10 10 11 11 12 12

	11 11 12 13 13 14 15 15
	11 12 12 13 14 15 15 16 

Fox 3:

        08 08 09 11 13 13 14 17
	08 08 11 12 13 14 17 18
	09 11 13 13 14 17 17 19

I know they're part of HCEnc. I've viewed them there myself.

I mean, who originally sourced them? And how?

It's easy to dump them from the stream with the right tool.

However be inform that some decoders (AFAIR broadcom) don't like situation when DC is lower than 8 (sometimes even lower than 16 on non-intra).

If I'm not wrong, ReStream dump the first set of matrices in the file. If the mpeg2 switch matrices at GOP level (like some encoders do) you can't log them all. With DGIndex, enabling "Log quantizer matrices" you can dump all the matrices used by the mpeg2.

Hmmm- now I'm not sure what I've used- maybe it was DGIndex, which does it "better" way. Don't remember
I think it was DGIndex

Who? The one called Fox 1 (aka Fox Home Theater) first showed up in a collection of XviD matrices as far as I know. It was obviously sourced from a 20th Century Fox DVD. I don't know the person that first made it available. The how has been explained elsewhere in this thread. It was probably done using ReStream as I don't believe DGIndex had that ability then.

The ones called Fox 2 and Fox 3 were supplied by me for Rockas's add-on to DVD-Rebuilder. Fox 2 I got from a DVD. Fox 3 I created from pieces of two others. I believe it was Hank that gave all three of them the names used in his encoder. The idea was that each compressed the video more than the one before (output a smaller file size), for the same quant value.

Rockas Matrix Editor uses Quantdump.exe:


Code:
[C:\]
=>quantdump
QuantDump 1.1 by Donald A. Graft
Usage: quantdump inputfile [outputfile]
       where input file is an elementary or program stream
       and outputfile will be written with the quant dump information.

Awesome! I can't wait to dig up some good looking DVDs in my collection and analyze them.

Just curious... but what are some of everyone's favorite looking DVDs (for comparison)?

AVInaptic. You need to put the raw stream in an MKV container. You'll see only matrices that differs from "Flat". So, basically, Flat matrix used -> no info about matrices. Something different -> values of 8x8/4x4 intra/inter matrices.

I did some tests with AVInaptic and only the 4x4 intra luma matrix was dumped. Does this mean all of the other matrices are flat?

Are there any other tools for MPEG-4 AVC/H.264 steams?
