AFD configurations.
AFD, VI, and WSS-Based Aspect Ratio Control
When you set the
ARC Control
parameter to follow the aspect ratio codes (
AFD,
AFD-ALTR, AFD-Custom Map, VI, VI-ALTR, VI-Custom Map, WSS, WSS-ALTR,
and
WSS-Custom Map
), the aspect ratio control is based on input AFD, VI, or WSS code.
AFD-Custom Map, VI-Custom Map,
and
WSS-Custom Map
make it possible for you to
perform automatic aspect ratio conversions based on the custom defined mapping table.
The other options set the ARC to an existing standard. When the input code is missing, the
ARC behavior is defined by
Loss of AFD ARC
,
Loss of VI ARC
or
Loss of WSS ARC.
Only
one of these options is be enabled at any one time.
Though they are not widely used, some AFD, VI or WSS codes recommend cropping part of
the image. When this type of cropping is enabled, the X100 will take longer to change ARC
modes. To create faster ARC transitions, you can disable the cropping using the
AFD Crop
Enable
parameter
in
ARC Control
.
When the ARC is based on AFD, VI, or WSS, and the output standard is SD-SDI, you must
set the
SD Out Aspect Ratio
(either 4:3 or 16:9) to ensure you use the correct mapping
table.
