A: Frame buffer is a temporary queue located
in the main memory, where compressed frames (images) are waiting
for their turn to be recorded to the hard drive. The process of
direct recording is a separate program thread, which operates
independently and has dynamic priority of execution. If captured
frames (images) arrive too fast and cannot be recorded on the
hard drive immediately, they will be stored in frame buffer for
later recording. The more frames are waiting in this queue, the
higher priority of recording will
be. The nearly filled frame buffer bar indicates that main processor
or disk drive are overloaded and recording settings such as fps,
resolution, quality should be lowered down.
