Frame Memory

Overview

A frame memory is a function that freezes and captures a
single frame of the input video for use as content. You can
also specify a range in the input video to create a clip
(frame memory series of still images).
You can also import a still image or video file created
externally for use as frame memory content.

Areas Used by Frame Memory

Two areas are used by frame memory.
Frame memory work area: An area for creating and
working with content.
This area is volatile memory, so when the system is
powered off the content in frame memory will be lost.
Content storage: Area for saving created content and
imported content.
When used for frame memory operations, the target
content is loaded into the frame memory work area.
Number of content resources that can be stored
The number of content resources (number of frames) that
can be stored in frame memory is given below.
Signal format Number of content resources
(frequency)
2160P 2SI Approx. 1640 frames
(59.94, 50)
1080P Approx. 6500 frames
(59.94, 50)
1080i Still image content: About 6500
(59.94, 50) frames
Video content: About 3250
frames
For combined content, the number of content resources
(number of frames) that can be stored is halved.

Frame Memory Input and Output

There are two systems for frame memory input: frame
memory source 1 bus and frame memory source 2 bus.
There are 16 channels for frame memory output: FM1 to
FM16. You can store and recall an image on each frame
memory output channel. By allocating FM1 to FM16 to
cross-point buttons, you can use frame memory output as
input content.
The two frame memory input systems are assigned to two
consecutive frame memory outputs (odd-numbered and
even-numbered frame memory output combinations, such
as FM1 & FM2 or FM3 & FM4).
Frame memory source 1 bus is used on the odd-numbered
frame memory output channel, and frame memory source
2 bus is used on the even-numbered frame memory output
channel.
Note
When the system signal format is 2160P, only six channels
comprising FM1 to FM6 can be used.
Group mode (combine channels)
When group mode is enabled on consecutive odd-
numbered and even-numbered frame memory output
channels, the two channels are combined.
Frame memory operations control the combined frame
memory output channels.
When combined content is selected, content 1 and content
2 of the combined content are recalled on the two
combined frame memory output channels, respectively.
V/K mode
When V/K mode is enabled, selecting a signal on the frame
memory source 1 bus will automatically select the paired
key signal on the frame memory source 2 bus.

Frame Memory Content

The following two types of content can be created in frame
memory.
