53 FS2 Installation and Operation Manual — Computer Video Formats
The following table lists FS2 scaling applied depending on which Downconvert or
Upconvert mode is selected.
Genlocking The FS2 does not genlock (synchronize) to computer format video inputs. If a
computer video input feeds Video Processor 1 or 2 and the current Genlock
Source (System Menu 8) is set to Vid1 Input or Vid 2 Input, the system
automatically defaults to Free Run mode. You can select Reference as the Genlock
Source and apply a broadcast video signal to the Reference input if you wish to
genlock to video rather than use Free Run mode.
Getting Your
Computer Working
with the FS2 Getting your computer to work with the FS2 is much like getting your computer
to work with a second monitor. Here's the recommended procedure:
1. Turn off the computer and the FS2.
2. Connect the computer video output to the FS2 HDMI input.
3. Turn on the FS2 and wait for it to boot completely.
4. Turn on the computer and wait for it to boot completely.
5. In the Windows 7 "Display" Control Panel, navigate to "Screen Resolution," and
confirm that a second monitor for the FS2 is displayed. Click on the "FS2" monitor
and adjust the settings as desired.
6. For Mac OS computers, open the System Preferences application, and click on
the "Display" icon (in the Hardware row). Click the FS2 monitor window and
adjust the settings as desired.
Downconvert Mode Upconvert Mode Frame Scaling
Letterbox 4x3 Pillar Scale the input frame until the longer dimension (H or V) touches the
output raster edges. The shorter dimension is filled with background
video. Maintains the original pixel aspect ratio.
Crop Wide Zoom Scale the input frame until the shorter dimension (H or V) touches the
output raster edges. The longer dimension is cut off (cropped) to fit the
output frame. Maintains the original pixel aspect ratio.
Anamorphic Full Screen Scale the input frame independently in H and V until both dimensions
fill the output raster. No cropping or background fill is required, but
the original pixel aspect ratio may be "stretched" to fill the output raster.
14x9 14x9 Pillar Compromise between Letterbox and Crop modes: some background
fill may be required in the shorter dimension to fill the output raster
(but not as much as Letterbox mode), and some cropping may be
required in the longer dimension to fit the output raster (but not as
much as Crop mode). Maintains the original pixel aspect ratio.
Auto AFD LB to Full When used with "computer format" inputs these modes default to
Letterbox / 4x3 Pillar behavior.
