However, disabling this option can sometimes be useful when using the codec with various compositing applications or
trying to export to another codec from QuickTime Player Pro. By disabling this option, the chance of gamma or color
conversion from YUV-> problems with QuickTime are reduced, however, the tradeoff is that applications that understand
and prefer 2vuy video data will be slower because the codec will only report to them as using RGB data. Thus, the
YUV->RGB color-space transformation will be forced to happen in the codec, using the matrix set in the YUV to RGB
Matrix option.
Enable High-Precision YUV
This option enables/disables support for 8- bit YUVA4444 ‘v408’, 8-bit YUVA4444 ‘r408’, 32-bit float YUVA4444 ‘r4fl’, 8-bit
YUV444 ‘v308’, and 10-bit YUV422 ‘v210’colorspaces. Enabling this option will not make the image better; however
enabling this option can help in certain applications that support these formats in their rendering pipelines.
Enable 16-bit RGB(A)
This option enables/disables support for 16- bit RGB ‘b48r’ and 16-bit RGBA ‘b64a’ colorspaces. Enabling this option will
not make the image better; however enabling this option can help in certain applications that support these formats in their
rendering pipelines.
