Press the enter key to view the load image menu. When the load image menu
is displayed, use the left and right arrow keys W X to determine the source of
the image to be loaded. The three options available are live input, load from
FDD and filename.
Live Input
This option is used to load images or patterns being presented, in real time,
on the "SDI Fill" and "SDI Key" inputs. The option is particularly useful for
keying external video signals, such as moving images from a character
generator.
If live input is selected for either the MG or FG stores, the grab facility will
be suspended from use (this applies even if the image is not on air). To regain
the "grab" facility, a new image must be loaded into the channel that has live
image selected.
Although the live input function is normally independent of the Background
SDI signal, it should be noted that, if the Imagestore is using the SDI digital
signal as a clocking source, that signal must be present.
Press the enter key and the Imagestore will begin to load the image. If no
signal is present at the Fill input, the operation will terminate.
Load from FDD
Imagestore requires the 3½" floppy disks used to be DOS-formatted
(1.44MB) and that the files be in a format shown in the following table. In
each case the image file extension must match the image format.
With the load from FDD prompt displayed, and with a disk in the drive, press
the enter key to load the file.
Full details of FDD image loading are found under Swap-Preview mode.
