RGB to YUV Gamma Correction
This settings enables you to control how Gamma is handled when converting RGB to YUV.
There are four options:
Off all Gamma Correction is turned off and the Source Gamma is used from the incoming frame.
CVBuffer Tag '2.22' The video buffer is ‘tagged’ with 2.22 – this means that QuickTime will auto-correct
incoming video frames to 2.22 Gamma.
CPU Gamma 1.8->2.22 Source Gamma is requested from the incoming RGB Video Frame; however when
converting from RGB->YUV via CPU a 1.8 to 2.22 Gamma Correction is applied. (1.8 is QuickTime Apple
Platform Gamma for RGB)
CPU Gamma 2.5->2.22 Source Gamma is requested from the incoming RGB Video Frame; however when
converting from RGB->YUV via CPU a 2.5 to 2.22 Gamma Correction is applied. (2.5 is QuickTime Windows
Platform Gamma for RGB)
Watermark (For Color Testing)
This option watermarks the video in the almost-top-left corner ( the watermark is adjusted about 400 pixels in from the left
side so that it is not covered up by watermarks from our Decode codecs) it is IMPORTANT to disable this option when
doing real work as the watermark will be a part of the encoded video this option is just meant for quick checks for the
user to see what colorspace Calibrated AVC-Intra Create is being handed by the calling application. The watermark is a
black rectangle. The top text will either be 8 or 10-bit YUV422 this indicates what the AVC-Intra video was encoded as.
The bottom text will either say Received 8-bit YUV422, Received 10-bit YUV422, Received 8-bit RGB444, Received 8-bit
RGBA4444, Received 16-bit RGB444, or Received 16-bit RGBA4444 this indicates the colorspace of the video frame
that the calling application is sending to be encoded.
Write SPS/PPS Every Frame (Advanced)
The parameter set data (SPS/PPS) is 512 bytes and stored in the first 512 bytes of the first frame. Checking this option
will write the SPS/PP2 512 byte packet to the beginning of every encoded frame.
