Shooting

Adjust the SC phase using the "SC PHASE" function on
PAGE 3 menu.
First set to between 0° and 180° for rough adjustment
using the "SC PHASE Rough", then use "SC PHASE
Fine" function for fine adjustment so that the reference
video signal and the output video signal have the same
carrier phase.
Use a vectorscope or the wiping function of a special-
effects generator so that images of both the reference
camera and the camera to be adjusted appear next to
each other on the screen.
