RABBING
The TSG/Image Grabbing Setup Menu is used to capture frames from video for use
as test patterns or keyed still images.
Grab 10-bit Video
Captures a 10-bit frame from video for use as a test pattern in the Test Signal
Generator.
When this option is selected, a frame is grabbed from the currently selected input
video signal. While the frame is grabbed, the video output will be briefly frozen, then
resume live operation.
The captured frame is saved as a file named Grabbed. This file must be renamed in
the Flash Memory Mgmt option of the System Config menu, or else it will be
overwritten by the next video grab.

Grab 8-bit Video
Captures an 8-bit frame from video for use with the unit’s linear keyer.
When this option is selected, a frame is grabbed from the currently selected input
video signal. While the frame is grabbed, the video output will be briefly frozen, then
resume live operation.
When used by itself, this option creates a still image file that will be output full-
screen by the keyer. The Grab Linear Key option (detailed later in this section) can be
used in conjunction to add a key channel, thus creating a file that will be keyed over
the incoming video. The Grab 8-bit Video option captures the fill (the “content” of the
keyed image); the Grab Linear Key option is then used immediately afterward to grab
an incoming key channel. (The key channel can be captured from a separate input, or
the connections of the currently selected video input must be changed to provide the
key signal.)
The captured frame is saved as a file named Grabbed. This file must be renamed in
the Flash Memory Mgmt option of the System Config menu, or else it will be
overwritten by the next video grab. The file should not be renamed until the
Grab Linear Key option has been applied, if a key channel is desired.
