Frame Memory
Operation modes
The frame memory has the following operation mode.
V/K mode: When the pair mode is active, the key signal is automatically
selected on frame memory source bus 2. This is convenient for handling
the video and key signals together in frame memory. For example, when
you select a video signal on frame memory source bus 1, the key signal
assigned to it is automatically selected on frame memory source bus 2. You
can also use the signal automatically selected on frame memory source bus
2 as a key signal when processing keyframe memory 1.
To change the pair mode or operation mode, use the Frame Memory menu.
Frame Memory Functions
The frame memory provides the following functions.
• Capturing an image
• Saving an image
• Recalling an image
• Processing an image
• Image output
• Image data management
• Image data transfer
Capturing an image (freeze)
As the input material for the frame memory, you can use the signal selected on
the frame memory source bus. For this signal you can use video processing
(video levels or hue value adjustment) or masking.
Allocating a frame memory source bus signal to one of FM1 to FM8, then
carrying out a freeze captures a still image in the corresponding frame memory
output image, and saves it in temporary memory.
For a freeze, an image can be captured either as video frame (a “frame freeze”)
or a video field (“field freeze”).
Note
When the system is powered off, any freeze images written to temporary
memory are lost.
