7.2 Frame Grabber Adjustments
A frame grabber is an electronic device that captures individual still frames from an
analog video signal or a digital video stream and transmits them in a digital form. An
Epiphan frame grabber is a subsystem component in the Lecture Recorder x2 and
can be configured separately. From the Web admin interface, select Frame Grabber
from the main menu to configure Frame Grabber adjustments.
The Lecture Recorder x2 automatically adjusts image capture settings every time it
starts up. The automatic image adjustment is repeated every 60 seconds during
operation. The interval between automatic adjustments can be changed to have
them occur more or less often. The capture settings attempt to produce the best
quality captured image for the equipment being used.
