QuickTime Gamma
QuickTime Gamma Correction (by Default ) is TURNED OFF
– we have found that this is what the vast MAJORITY of
users prefer
– however in certain applications this can produce rendered video that is slightly brighter/darker than the
source video usually when rendering to another QuickTime codec - to correct please TURN ON QuickTime Gamma
Correction. Please see the Gamma Settings in the Global Options Chapter.
Important note about 8-bit YUV colorspace
Calibrated{Q} DVCProHD Decode supports decoding to 8-bit YUV422 (the colorspace that DVCProHD is encoded in) -
however it is up to the application using Calibrated{Q} DVCProHD Decode to request 8-bit YUV422 colorspace. Many
applications that support importing MOV files only request 8-bit RGB(A) 444(4) colorspace, which requires a colorspace
conversion of YUV->RGB in the codec
– which slows down performance. Please see the Colorspace Watermark in the
Global Options Chapter to see which colorspace on application is requesting, and also see the Enable 8-bit YUV, Enable
High-Precision YUV, and Enable 16-bit RGB(A) in the Global Options Chapter to learn more about the various colorspace
support.
