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.
You can also play recorded frame memory clips (movies).
Image storage capacity
The frame memory board has two blocks of memory, and
the following table shows the maximum number of images
that can be written to each block.
One of the two memory blocks is used as the destination
for storing frame memory clips.
