Switching with Mix Transitions

Mixes are transitions in which the next video fades into the
original video, finally replacing it. You can choose from
among the following three types of mix transitions.
• MIX transition
This is a transition in which the original video gradually
fades out while the next video gradually fades in. At the
midpoint of the transition (with the fader lever at the center
of its range) the output levels of the original and the next
video are both 50%.
• FAM (full additive mix) transition
This is a transition in which the next video gradually fades
in to cover the original video, which is unchanged at the
start of the transition. At the midpoint of the transition, the
output levels of the original and the next video are both
100%. Then the original video begins to gradually fade
out.
• NAM (non-additive mix) transition
The output levels of the original and next video vary in the
same way as FAM, but instead of adding the two video
signals for output to program output, the two signals are
compared and only the signal with the highest luminance
level is output.
Basic mix operations
Use the following procedure to switch between video
signals by using a mix.
