the key to 50% so you can see the shot clock through the video which will help you
align the corners of the image to the background video (the shot clock). The opacity
can be changed using the View Thru Opacity data pad or soft knob.
11 Select a Corner Adjust button— Top Left , Top Right , Bottom Left , or Bottom Right , and
use the Corner Adjust X and Corner Adjust Y soft knobs to pin the corner to the corner
of the shot clock in the background video. This will allow you very precise adjustment.
Repeat for each corner.
12 Turn off the View Thru Enable feature.
If the background video changes, you can re-center the image (shot clock in the example)
using the
Pan and Scan crop buttons. You ‘Pan’ the crop; move the crop sideways which
simultaneously trims the value of the Left Crop and Right Crop, or ‘Scan’ the crop; move the
crop up and down, which simultaneously trims the Top Crop and Bottom Crop values.
