Switching the Picture Using the Video Fader
1. Check which channels are currently selected.
Before you carry out a transition operation, check which channels are currently selected. At powerup of the V-4EX, channel 1 is
selected for the A-Bus input selectors, and channel 2 is selected for the B-Bus input selectors. The bus corresponding to the end
to which the video fader has been moved is output, and when the built-in monitor is in the INPUT mode, a red border is displayed
around the output picture. A green border is displayed around the picture on the opposite bus (the standby video).

are displayed around both pictures.
