effects, however, it is referred to as a Resizer, other companies also refer to 2D
effects as DVE.
DME Wipe
A DME wipe is a wipe transition that uses a DME effect to change from one
video image to the next. There are two types of DME wipe: those which can be
selected for a normal transition, and those which can be selected for an
independent key transition.
<Note> On the MVS-8000G, it is also possible to carry out a DME wipe on a key
using the resizer.
DME Wipe Snap
Snapshot and save a DME wipe pattern together with the current settings of its
modifiers and pattern limit, ether in a flexipad module or 10 key module with a
dedicated register for recall when required. There are 99 DME wipe snapshot
registers for each of the M/E and P/P banks.
