Selecting The Transition Type - Sony DVS-7300 System User Manual

Selecting the Transition Type

The most basic distinction is between an instantaneous transition, or cut, and
the various types of gradual transition.
The system provides the following types of gradual 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.
