Appendix A — General Registry Settings

The IBM Video Registry Table
Allowable Combinations of Video Properties
The table below lists acceptable combinations of video format, chroma, mode,
horizontal resolution, and vertical resolution.
NOTES:
(1) The MPEG Specifications allow integral settings of 8 through 10. The IBM chip set also
allows a non-standard setting of 11. The Filter Manager forces a setting of 8 whenever SIF resolution
is specified, regardless of the value stored in the Registry.
(2) In most cases, the IBM encoder will override this setting based on the compression type.
(3) Note that the last 7 entries in the IBM Video Registry table were stored in the ArgusConfig.txt
configuration file in releases prior to 2.3. The configuration file is no longer used in versions 2.3 and
later; all of its entries have been moved to the Windows Registry.
(4) For frame-accurate endings, both RefFrameDistance and IFrameDistance should be set to 1.
(5) If the VBR flag is set to 1, turning on variable-bit-rate encoding, the BitRate setting specifies the
maximum video bit rate, while the VBRAvgBitRate key specifies the average bit rate.
