Still Image Storage
Video and key can be frozen either separately or simultaneously
through the use of panel controls. In addition, the system has the
ability to layer stills in a recursive manner. The system
accomplishes this by sending the output of the frame store to the
input of an M/E for combination with another image. A
composite is generated that can be fed back to the input of the
frame store and re-frozen.
Building A Recursive Effect
1.
Set up an effect on an M/E.
2.
Select the M/E on Aux Bus 4.
3.
Turn
FRZ
(freeze) on.
4.
Select the crosspoint on the M/E.
5.
Select new key source and press GRAB.
6.
Repeat the previous step with new sources.
Hint: Experiment with Preset Patterns and try different shapes.
