Selecting The Transition Type - Sony DVS-7300 User Manual

Selecting the Transition Type

The system provides the following types of transition; to select one of these,
press the corresponding button in the transition control section, turning it on.
Transition type
Normal mix dissolve
NAM (non-additive mix) dissolve
Super Mix dissolve
Wipe
DME wipe
The following sections illustrate each of these transition types.
Normal mix dissolve
In a dissolve, the new video fades in as the old video fades out. Using a
normal mix, the new video level is increased from 0% to 100% as the old
video is reduced from 100% to 0%, in such a way that the overall signal level
is always 100%. At the mid-point of the transition (when the fader lever is in
the center position), the output of each signal is 50%.
NAM (non-additive mix) dissolve
In this variant dissolve, the video signals are combined by a non-additive
mix, and the new video level is increased from 0% to 100% over the first half
of the transition, and the old video is reduced from 100% to 0% over the
second half. A non-additive mix means that the two video signals are
compared, and the higher one is used as the output; thus new highlights fade
in first, and old highlights fade out last.
