The DD35 Production Switchers provide extensive masking capabilities which
enable the operator to correct even difficult pictures. For the keyers, rectangular
masks are available. As an alternative, the wipe patterns of the wipe generator may
be used for masking. The volatile masks store offer new ways of masking. A key
signal or a pattern signal may be stored. The PaintModeMasking feature permits
the creation of masks which are perfectly adapted to the individual requirements.
With the Ext. Mask (Bus) external created masks can also be used for masking.
All Postion and Shift functions can be controlled via mouse.
