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,.
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%,.
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.
Variable Adjusts black level limit from -10 IRE to +20 IRE in 0.5 steps.
Default (unity): 0 IRE
Variable Adjusts chroma clip level from +60% to +140% in 0.5 steps.
Default (unity): 100 IRE
OFF (default) The FS2 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 the FS2 is 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.
>16:9 The FS2 always inserts a “Box > 16:9 (center)” AFD code (4), which indicates that the HD
image has an aspect ratio greater than 16:9 as a vertically centered letterbox within
the 16:9 frame.
Full Frame The FS2 always inserts a “Full Frame” AFD code (8), which indicates that the HD image is
full frame, with an aspect ratio that is 16:9.
Pillarbox The FS2 always inserts a “4:3 (center)” AFD code (9), which indicates that the HD image
has a 4:3 aspect ratio as a horizontally center pillarbox image within the 16:9 frame.
Letterbox The FS2 always inserts a “16:9 (with complete 16:9 image protected)” AFD code (10),
which indicates that the HD image is full frame, with a 16:9 aspect ratio and all image
areas are protected.
14:9 The FS2 always inserts a “14:9 (center)” AFD code (11), which indicates that the HD
image has a 14:9 aspect ratio as a horizontally centered pillarbox within the 16:9
frame.
4:3 Alt 14:9 The FS2 always inserts a “4:3 (with alternate 14:9 center)” AFD code (13), which
indicates that the HD image has a 4:3 aspect ratio and with an alternative 14:9
centered pillarbox image within the 16:9 frame.
16:9 Alt 14:9 The FS2 always inserts a “16:9 (with alternative 14:9 center” AFD code (14), which
indicates that the HD image has a 16:9 aspect ratio with an alternative 14:9 center
within the 16:9 frame.
16:9 Alt 4:3 The FS2 always inserts a “16:9 (with alternative 4:3 center)” AFD code (15), which
indicates that the HD image has a 16:9 aspect ratio with an alternative 4:3 center
within the 16:9 frame.
