any luma/chroma that exceed the set limits. In RGB mode only the White Clip and
Black Clip controls are active and limit the R, G, and B values to those settings.
RGB mode requires the video to pass through the RGB Proc Amp to be converted
to and from RGB.
Off (default)
YUV
RGB
Disables the Video Legalizer.
Enables the Video Legalizer to clip YUV to legal levels.
Enables the Video Legalizer to clip RGB to legal levels.
16.1 Legalizer White Clip
When the Video Legalizer mode is YUV or RGB, this parameter limits the white
level so that it does not exceed the adjusted limit. Limit can be set from +80 IRE to
+120 IRE.
Variable
Adjusts white clip level from +80 IRE to +120 IRE in 0.5 steps.
Default (unity):
100 IRE
16.2 Legalizer Black Clip
When the Video Legalizer mode is YUV or RGB, this parameter limits the black
level to the adjusted limit. Limit can be set from -10 IRE to +20 IRE,.
Variable
Adjusts black level limit from -10 IRE to +20 IRE in 0.5 steps.
Default (unity): 0 IRE
16.3 Legalizer Chroma Clip
When the Video Legalizer mode is YUV, this parameter limits the maximum
chroma level to the adjusted limit. The limit can be set from +60% to +140%,.
Variable
Adjusts chroma clip level from +60% to +140% in 0.5 steps.
Default (unity): 100 IRE
AFD
These parameters determines if and where the Video Processor will insert
a SMPTE 2016 Active Format Descriptor (AFD) packet into its output video.
The inserted AFD code does not affect the Video Processor’s up/down/cross
conversion, but it may affect downstream video processing if the signal is
Downconverted.
NOTE: AFD codes are only inserted into HD video outputs.
17.1 AFD Out SDI 1/2
These determines whether the Video Processor inserts an ADF packet into the
output video.
OFF
(default)
Does not insert an AFD code into the output. If the video input has a AFD code and the
FS2 is not up/down/cross-converting it, the input AFD code will be passed through to
the output.
Auto
If not Upconverting or Downconverting the input video, the input AFD code is passed
through. If there is no AFD code on the input video, a “Full Frame” (8) code is
inserted. If the FS2 is Upconverting, the appropriate AFD code will be chosen based
on the Upconvert mode.
