Video and key can be frozen either separately or simultaneously 
through the use of panel controls. In addition, the system has 
read-before-write capability, so stills can be layered 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.

The

 button turns shadow mode on and off.

When shadow mode is on, the

and

 knobs adjust the horizontal and vertical 

offset of the shadow from the main key signal. A third 
knob,

adjusts the opacity of the shadow.

Shadow On mode is functional only with primary video inputs 
that have an associated linear key signal or an M/E in layered 
mode. No clip and gain adjustments are available to the user. 
Shadow On mode does not reduce the bandwidth of the key 
channel.

Shadow On is added to the key signal; the video output is 
unaffected. Therefore the Frame Store video and key must be 
composited on top of another layer in order to see the shadow.
