The Input Aspect Ratio Submenu, shown in the following illustration, provides one way to
affect aspect ratio. The ImagePRO-II selects and displays the input video aspect ratio
according to the selected input format.
Figure 4-3. The Input Aspect Ratio Submenu
With the 3D/Dual Channel mezzanine installed and the system set to dual-channel mode,
Input Aspect Ratio provides an additional option to set the aspect ratio for each channel.
Figure 4-4. The Input Aspect Ratio Submenu in Dual-Channel Mode
The settings on this menu can be overridden by the input horizontal and vertical Zoom
settings. If you override the settings, this menu may not display the input’s actual aspect
ratio.
To select the Input Aspect Ratio Submenu from the Input Menu, scroll to Aspect Ratio
and press SEL. Then scroll to one of the following options:
• Set Mode — The Set Mode value is one of the following: 1:1, 3:2, 5:4, 16:9, or
Custom. The ImagePRO-II detects the input format, and displays the appropriate
aspect ratio.
 Example: Computer video at 1280x1024 @ 60 Hz defaults to 5:4.
 Example: NTSC video defaults to 4:3.
 Example: HDTV1080i video defaults to 16:9.
• Ratio — This option is available only when Set Mode is set to Custom. It is a
decimal number ranging from 0.750 to 3.000.

The Sizing Adjust Submenu lets you:
• Scale the selected input video up (or down) within the current active area.
• Mask (crop) an image, either one edge at a time, or by using preset masks of all
four edges to achieve a specific aspect ratio.
As you adjust sizing, the top and bottom portions of an image may fall outside of the raster,
for example, when a 4:3 image is scaled up to 16:9.
