Frame Memory

Overview

Frame memory is a function whereby a frame of input video can be frozen and
written to memory, for further use as material for editing.
In an MVS-8000 HD system the maximum number of image frames that can
be written to memory is 58 (88 frames in 720p/59.94 format), and in an SD
system a maximum of 222 frames.
In an MVS-8000A system, regardless of the signal format, the maximum is 444
frames.
For details of operations, see "Frame Memory Operations" (page 420).
Use of frame memory
There are eight frame memory channels, FM1 to FM8, and each channel
independently allows a freeze image to be saved or recalled.
By allocating FM1 to FM8 to cross-point buttons you can use the still image
output from each channel as input material. The "still image" refers to a freeze
image written to temporary memory or a file saved (stored) in memory.
Correspondence between input and output
There are two buses for capturing frame memory material: the frame memory
source 1 bus and the frame memory source 2 bus.
These input buses are used by allocation to one of the pairs of output, FM1&2,
FM3&4, FM5&6, and FM7&8. You can freeze a frame in each channel
separately, or freeze in the two channels simultaneously.
The source buses allocated to FM1 to FM8 are as follows.

Pair mode
By enabling the pair mode, you can link FM1 and FM2, FM3 and FM4, FM5
and FM6, and FM7 and FM8. For example, when a freeze or image processing
is carried out on FM1, the same operation is carried out on FM2. The same
