Frame Memory

Overview

A frame memory is a function that freezes and captures a
single frame of the input video feed as a still image for later
use. You can also specify a range in the input video to
create still images to form a frame memory clip.

Installation of the XKS-8440 Frame Memory Board is
required to use the frame memory function.

Frame memory storage area

There are two storage areas on the frame memory board.

Memory:

Volatile memory used for operation. When the

system is powered off, files and folders in memory are
lost.

Storage:

Non-volatile memory for storage. This space is

used for storing created image data files. When used
for frame memory operations, the target file is loaded
into memory.

After loading a file, performing a file operation in storage,
such as renaming or deleting, will delete the file from
memory.

Image data storage capacity

The number of images that can be stored in memory is
given below.

Frame Memory Image Data

The following two types of image data can be manipulated
in frame memory. When there is no distinction being made
between image data types, image data is referred to as just
an “image.”

Still image:

A single image in the input video is frozen and

saved. Each file (still file) holds just one still image.

Clip:

A clip is created by a series of still images, which is

played back like a video. The collection of files
constituting a clip is referred to as a “clip file.”

Notes on saving or recalling a frame memory in a
snapshot/keyframe

• Only still images and clips recalled to FM outputs (FM1

to FM20) can be the target of snapshots or keyframes.

• If a frame memory is recalled due to a snapshot or

keyframe, the still image or clip must exist in memory
under the same conditions as when it was saved. Load
the target image in memory beforehand so that it is
available for use when the recall operation occurs.

Frame memory input and output

There are two lines for frame memory input: frame
memory source 1 bus and frame memory source 2 bus.
There are 20 frame memory output channels, FM1 to
FM20, and each channel independently allows an image to
be saved or recalled. By assigning FM1 to FM20 to cross-
point buttons you can use the image output from each
channel as input material.
