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.
