• Low, Med, and High quality settings -- allow you to specify the amount
of detail in the transmitted video. High quality transmits the most detailed
images, but at the expense of CPU and network bandwidth. The use of
Custom quality settings is strongly discouraged unless you are highly
knowledgeable. Note that the two clients in a video call negotiate to a
common video quality that is acceptable to both, so delivered image
quality may vary from call to call.
• Format button -- produces another window that allows you to specify the
size and internal organization of the video image. The window typically
appears as shown in the following figures. This window will vary from
camera to camera.
Note: There is no tool or formula that allows you to compute the
network bandwidth (in bits per second) for an arbitrary combination of
video settings. However, network bandwidth increases with increasing
quality.
