Hidden Settings
These are settings not available via the GUI, but can be set in the 'Rebuilder.ini' file in the your DVD ReBuilder program directory. (Note: this is not the same as the file created in the WORKING directory named 'Rebuilder.ini'). These settings are for advanced users, otherwise they wouldn't be hidden.

All optional settings MUST be placed in the '[Options]' section of the .ini file, otherwise they will be ignored. Any settings changed here will not be activated until the next time you run DVD-RB.

 
  • Target Output Size

    TargetSectors= nnnn
    CCETargetSectors=nnnn
    ReJigTargetSectors=nnnn
    QuEncTargetSectors=nnnn

    Use Sectors, 1 sector = 2Kb.
    Example: CCETargetSectors=2236400

    As a reference the default for DVD-RB is 2236400 sectors and the maximum for a DVD-5 is 2297888. You should always leave a some room for error.

    TargetSectors will be the default for all methods. Other, mode specific, target sector settings will override it when using that mode.

     
  • Minimum and Maximum Bitrates Effects CCE MODE only.

    min_bitrate=nnnn
    max_bitrate=nnnn

    Use Kbps.
    Example: max_bitrate=9000

    No error checking is done on the numbers so take care. Setting them incorrectly can seriously degrade the quality of the picture. Also note that changing them can cause oversized or undersized output.

     
  • VTS Minimium Size Re-Encode Threshold

    vts_min_size=n

    Range:0-?, Default: 25625 (~52 MB)

    The parameter specifies the number of sectors (2048 bytes each) that defines the point at which a VTS will be either encoded or copies intact. Anything this size or smaller will be simply copied into the output VIDEO_TS directory (it won't be further compressed).

     
  • One-Pass Analysis Options

    Q_sample_percentage=n

    Range: .1 - 25, Default: 1.0

    Specifies what percentage of the video will be analyzed in order to estimate the final video size. Increasing this number may improve file size accuracy in OPV mode, at the cost of increased analysis time.

    Q_ROM_constant=n

    Range: 200 - 300, Default: 256

    Used to estimate a Rough Order of Magnitude (ROM) Q value for the first pass using the formula:

    Q = (framecount / targetsectors) * Q_ROM_Constant

    Changing this should not affect the final output, but may reduce the number of analysis passes needed to find the final Q value. This shouldn't be changed unless you find DVD-RB consistently over/under estimating the initial Q value for your source material.
