• The line above the horizontal axis indicates the video receive bitrate of a sender. Senders are distinguished from each other by color.
• The upward red burr indicates video freezes.

• The downward red burr indicates audio freezes.

If you find that the call quality of a sender is low, click View Details in the upper right corner of the panel. Select the sender in the Video Subscription, Audio Subscription, and Presentation Subscription tabs, respectively, to view details about its audio and video quality indicators.
