V IDEO M ODE Specifies how the Vertigo hardware device passes through video.
•
B ACKGROUND V IDEO O N : The Vertigo device will always display the
video input as the back most layer, even without any scene loaded.
• V IDEO O N C LEAR : When the Vertigo device has nothing to render (no
scenes have been loaded), it will display the video input.
• B LACK O N C LEAR : When the Vertigo device has nothing to render (no
scenes have been loaded), it will render nothing, displaying black.
O N B OARD C OMPOSITOR Allows the off loading of certain color conversion routines from the CPU to
the video card. This feature is dependant on the correct firmware options
being installed on the hardware.
C OMPRESS K EY S IGNAL When this setting is enabled, the key signal color space is compressed so
it does not fall into super black or super white. The full 10-bit color space is
from 0 – 1023. The key signal is compressed into the range 64 – 940.
Above 940 is super white and below 64 is super black.
C LIP S UPER B LACK &
S UPER W HITE
Determines whether or not the VertigoXG allows the output to be in the
super black & super white range. The luminance range of a 10-bit SDI
signal is from 0 to 1023. A value below 64 is considered super black and a
value above 940 is considered super white. When this setting is enabled,
the VertigoXG will clip any pixels below 64 up to 64 and any pixels above
940 down to 940.
I/O B UFFERING Together these I/O buffering values determine the video delay of the
passthrough.
•
I NPUT : The number of buffered (frames) used for video input.
• O UTPUT : The number of buffers (fields) used for video output.
YUV P ROCESSING Specifies if color conversion of video input is off-loaded from the CPU to the
GPU.
•
CPU: Use the CPU to do the conversion.
• GPU: Use the GPU to do the conversion. The GPU is not
recommended, however, for HD video.
• GPU-PS: Uses the pixel shader to do YUV to RGB conversion.
F ILL D ELAY • H ORIZONTAL : The slider adjusts the horizontal (nanoseconds) timing of
the fill signal.
• V ERTICAL : The slider adjusts the vertical (lines) timing of the fill signal.
• H ORIZONTAL ( FINE ): The slider offers you a finer (smaller increments)
control of the horizontal timing delay of the Fill signal.
