RB-Opt and matrices

[TheSeeker]

Just wondering what matrices should be used in what instances when using rb-opt with DVDRB. I just discovered RB-Opt and would like to take advantage of some of the features it offers. one of which being custom matrices but there are no readme files whatsoever explaining what some of the matrices included with rb-opt are for. I means some are obvious like very low bitrate or ultra low bitrate but most are not obvious. Can anyone help me out with some info and maybe a page to download some more good matrices for use in dvd encoding?

I think it's good to encode a single .avs with different matrices, and then use in the full project the one which gives better results.
Default matrices (standard) are very good for normal bitrates; for higher bitrates you could try "Mpeg Standard" ones.
For low bitrates there are the default ones (Very Low and Ultralow), but you can find also other ones (ex.: the famous Notch matrices). Give a look to the ones in the matrices.zip (matrices found by eDealer): there is a .pdf in german and english to explain some details.

P.S.:
there is a bug in RB-Opt: the matrices you select are used for the full disk, and not in the single VobID. Bug is fixed, and soon I'll post a new version.

Personally I like the KVCD "Notch" matrix for low-bitrate encodes (generally anything under 3500 kbps). I find it does a good job reducing blockiness.

@SansGrip

Is the KVCD Notch matrice included in the rb-opt package. IF not where would i go about getting it?

I don't know if it is. In case not, here:

08 09 12 22 26 27 29 34
09 10 14 26 27 29 34 37
12 14 18 27 29 34 37 38
22 26 27 31 36 37 38 40
26 27 29 36 39 38 40 48
27 29 34 37 38 40 48 58
29 34 37 38 40 48 58 69
34 37 38 40 48 58 69 79
16 18 20 22 24 26 28 30
18 20 22 24 26 28 30 32
20 22 24 26 28 30 32 34
22 24 26 30 32 32 34 36
24 26 28 32 34 34 36 38
26 28 30 32 34 36 38 40
28 30 32 34 36 38 42 42
30 32 34 36 38 40 42 44

Note: Each line starts with a tab, then the first number. Each number is separated by a single space. Each line is terminated by a newline without any additional whitespace. (I don't know if CCE/RB-Opt is more lenient with the format, but the above works for me.)

It wasn't included in the package.
