which of these 2 matrices removes more detail?

[djskribbles]

which matrix removes more detail, AUTOQ1 or the "HC" matrix?
this is AUTOQ1:
8 16 19 22 26 27 29 34
16 16 22 24 27 29 34 35
19 22 26 27 29 34 35 38
22 22 26 27 29 34 35 40
22 26 27 29 32 35 40 48
26 27 29 32 35 40 48 50
26 27 29 35 40 48 50 60
27 29 35 40 48 50 60 62

16 20 24 28 32 36 40 44
20 24 28 32 36 40 44 48
24 28 32 36 40 44 48 52
28 32 36 40 44 48 52 56
32 36 40 44 48 52 56 58
36 40 44 48 52 56 58 60
40 44 48 52 56 58 60 62
44 48 52 56 58 60 62 62

and this is the "HC" matrix:
8 9 13 20 23 27 29 34
9 11 16 23 26 29 34 39
12 16 21 25 28 33 39 45
15 20 25 28 33 38 44 52
19 24 28 33 38 43 51 60
23 27 32 38 42 49 58 68
27 31 37 42 48 57 67 77
30 36 41 47 55 65 76 87

16 16 18 20 22 24 27 30
16 17 19 22 24 27 30 34
18 19 22 24 27 30 34 39
20 22 24 27 30 34 39 45
22 24 27 30 34 39 45 52
24 27 30 34 39 45 52 60
27 30 34 39 45 52 60 69
30 34 39 45 52 60 69 79

i realize that both of these matrices are targeted for lower bitrates (which is what i need), but i don't know what these numbers mean.

I guess you are trying to find out which matrix will keep more detail at low bitrate also. I am for KVCD matrix and am quite happy with the results.

Havent tried AutoQ1 though.

Hi-

Run one OPV/CQ encode with each on something short, a chapter of a DVD or something. The one that has the larger filesize when done is the sharper and retains more detail. That won't necessarily tell you which is the better matrix, though.

I'd do it myself, but I'm encoding at the moment.

thanks.

i did an OPV with CCE of a 4min clip from Gladiator, and both outputs are the exact same size. is this coincidence, or did i do something wrong?

edit: even though i selected the matrices i wanted, it used the original matrix of the movie for both encodes.

you know what... nm, i encoded the movie im doing with both matrices, and i've decided which one to use.

thanks for the help, though.

Hi-

Although it looks to me like they compress fairly similarly, if they came out with the exact same size, I think maybe you used the same matrix for both encodes accidently. You can check the ECL to see which matrix was used for the second encode. Maybe it'll be the same as the one you used for the first encode.

If you are using CCE Basic, I don't think that it will use any custom matrix.

see this thread (http://forum.doom9.org/showthread.php?p=826257#post826257)

If he were using CCE Basic he couldn't have done the OPV encode... so I think its safe to assume he's using SP.

Sorry

[jdobbs]

No need to be sorry -- I was just pointing it out. ;) Any and all help is appreciated here.

i checked what matrix was used for both encodes with RME, and the original matrix that was used with Gladiator was used (which appears to be FOX entertainment). maybe because no compression was needed (it was only a small ~170mb file), it didnt encode the video?
