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.
