Video Output
Mode The selection determines the final video output of the Video Processor. Alarms
occur if conflicting video formats are selected.
Background Fill Background Fill selects the background source used to fill any part of the UFC output
raster not filled with video from the main input video. For the Video Processor 1
menu, the second selection is Video 2. For the Video Processor 2 menu, the second
selection is Video 1. Using this feature, you can key Video 2 into Video 1 or vice versa.
Loss of Input Loss of Input selects the automatic action that occurs if the video input is lost. The
Black selection (default) cuts the video to black. The Freeze selection freezes video
on the last available frame.
Upconvert Mode Upconvert Mode selects the type of Upconversion the Video Processor performs on
the selected SD source input.
This parameter is in effect only when the input is SD (525i or 625i) and the selected
output format is HD (720p, 1080i, or 1080p), or when the input is HD (720p, 1080i, or
1080p) and the output is 2K (2048 x 1080).
When upconverting to 2K, the selections do not precisely describe the resulting
picture. For example, 4x3 pillar is not precisely 4x3, and 14x9 is not precisely 14x9.
