Set the bitrate mode (constant or variable) for Video.
| HRESULT SetVideoVBRMode(BitrateMode vbrMode); |
Parameters
vbrMode: BitrateMode enumeration value to set as the video VBR mode.
Remarks
You can set the filter to create either Variable Bitrate Video (VBR), or Constant Bitrate Video (CBR). When VBR mode is turned on, the Quality setting is used to determine the quality/size of the output and the bitrate value is ignored.
Conversely, when CBR mode is on, the quality setting is ignored, and the video bitrate is used.
