Cropping
Cropping a channel allows you to bring the sides of a channel in, reducing the viewable area, but
not changing the actual size of the channel. The menus display a graphic box labelled Cropping
that shows how the original channel is being cropped. Cropping values range from 0.000 to
1.000, from no cropping to full cropping respectively. Full cropping results in none of the
channel being displayed on the screen.
Use the following procedure to adjust the cropping of a channel:
1. Press the SEL button on the Keyers Module for the Keyer that you want to adjust the
cropping of the channel for. The S&T MD Position/Crop Menu 1-2 is displayed. The
key must already be flying.
2. Press More.
3. Adjust the horizontal cropping of the channel as follows:
• Press Crop Horizontal on the S&T MD Position/Crop Menu 2-2.
