Frame Store Subpanel
Still Image Storage
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.
Frame Store Shadow Controls
The Shadow On button turns shadow mode on and off.
When shadow mode is on, the Horizontal POSITION and
Vertical POSITION
knobs adjust the horizontal and vertical
offset of the shadow from the main key signal. A third
knob, OPACITY 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.
