Region of Interest (ROI)
The Region of Interest parameters (14.0–14.4) select a portion of the input picture
that will be used for scaling and/or positioning. This feature can be useful for
focusing in on computer video that is less than full screen, such as the contents
of a movie player window. The selected area can then be scaled to a standard
pillarbox or letterbox size and shape (On Square), or it can be set to a full screen
input image (On Full).
NOTE: On Full may cause image distortion if it is used to expand an odd-shaped region
of interest to full screen.
The ROI Setup mode allows you to preview the edges of your selected Region Of
Interest as you set it up. After selecting the desired region using the Setup Cursor,
you can take the region to air by setting Region Of Interest to On Square or On
Full.
Note that the Setup mode is not required to operate the ROI feature. The edges of
the Region Of Interest can also be adjusted while in On Square or On Full modes
14.0 Region of Interest
This parameter turns the Region of Interest settings On or Off. When enabled, the
ROI Left, Right, Top, and Bottom controls (14.1–14.4) define the rectangular shape
and position of the ROI.

Interactions occur between ROI settings and other parameters:
• The Region of Interest menu is not displayed when Active Format Description
(AFD) is in control of the Conversion Mode. While downconverting, with
Downconvert Mode set to Auto AFD, any values assigned for Custom Size/Pos
parameters are ignored, and the menus are hidden.
• Custom Size and Position settings work interactively with ROI, but Custom
Crop settings are disabled. Custom Size/Pos is also temporarily disabled while
in the ROI Setup mode.
14.1 ROI Left
This parameter sets the left boundary of the ROI when parameter 14.0 is on.
Variable
(default=100%)
Sets ROI left boundary to 10-100% of full screen in 0.1% increments.
For 1% increments, hold down the Video button.
14.2 ROI Right
This parameter sets the right boundary of the ROI when parameter 14.0 is on.
Variable
(default=100%)
Sets ROI right boundary to 10-100% of full screen in 0.1% increments.
For 1% increments, hold down the Video button.
14.3 ROI Top
This parameter sets the top boundary of the ROI when parameter 14.0 is on.
Variable
(default=100%)
Sets ROI top boundary to 10-100% of full screen in 0.1% increments.
For 1% increments, hold down the Video button.
