iChat Icon   Monitoring a video chat

To monitor the frame rate and bit rate of your video chat:

Choose Video > Connection Doctor.

The Frame Rate setting shows the number of frames the video plays per second (fps). The Bit Rate setting shows the average number of bits that one second of video data will consume (in kilobits per second, or kbps).

You can also keep track of how long the chat lasts in the Call Duration field.
