RB-Opt v0.23 BETA a tool to change titles bitrate, CCE parameters and AVS scripts.

[robot1]

It's coded in few nights... so it still has bugs (like every beta...)
It should work with every encoder supported by DVD-RB.

Sorry for my english... it's not my mother language.

RB-Opt is an addon for DVD-RB (0.4x-1.x free and PRO)
It allows the user to select different bitrates for every Title in a DVD to process by DVD-RB. For example, backing up a DVD you may want to lower the bitrates for the extras, leaving more room to the film. It works even for extras in the same VTS of the film (ex. Trailers, deleted scenes...)
RB-Opt allows to change also CCE parameters and .avs scripts, to use your custom setup for backup.
Since v0.13 RB-Opt supports OPV mode: thanks to SansGrip for the coding.

Latest version:
RB-Opt v0.38 beta (mirror by Doom9.de)


Previous versions:
RB-Opt v0.37 beta (mirror by jdobbs)
RB-Opt v0.33 beta
RB-Opt v0.29 beta

Usage:
Put DVD-RB in "3 click mode", and run the "Prepare" stage.
Now run RB-Opt, and open the REBUILDER.INF created by DBD-RB.
RB-Opt shows the default bitrate used for every title in the "Encode" stage.
Find (using preview) the Vob-IDs of the film, and link them (mandatory to have the best results).
Select the title you want to compress more/less, and input your custom bitrate.
The program will calculate the new bitrate for the titles labeled as "Auto".
It's just like DVDShrink and other one-click apps do ... in a less graphical way :-(
Now you can tweak end credits cell, initial cell, or use "expert settings" to tweak any CCE parameters, or to apply an avisynth filter.
For every title you can select if it will be encoded as VBR or OPV. For OPV titles the program will run a prediction step to find the right Q factor, unless you select a custom Q to override prediction.
After saving the changes, you can start the encoding stage in DVD-RB

The bitrate is always calculated cell by cell: if in DVD-RB you selected "Dynamically Assign Cell Bitrates", the resultant Cell Bitrates will be still proportional to the original ones.

Avisynth editing allows to insert a filter in every .avs of a Vob-ID, and uses "favourite filters" for faster editing. It allows to preview the cell, to control the filter behaviour.
You can change these CCE parameters, for every Vob-ID:
- Number of passes
- DC Precision
- Gop Length
- Quantizer Characteristics
- Bias
- Min/Max bitrate for VBR
- Matrices
- CCE internal Filters
