| VIDEO PERFORMANCE |
Dedicated encoder conferences: One transcoder per participant delivers any
resolution, frame rate or bandwidth without affecting any other caller
Shared encoder conferences: Two transcoders per conference—1080p, 720p, 480p, 360p
Conferences set at 1080p30, 720p60 and 720p30: 1 encoder above 384 Kbps, 1 below 384 Kbps
Conferences set at 480p and 360p: 1 encoder above 128 Kbps, 1 below 128 Kbps
Video bandwidth: 128 Kbps to 4 Mbps per port
Video resolutions: 720p at 60 frames per second; 1080p, 720p, 480p, 360p all at 30
frames per second; 360p increased capacity mode at 20 frames per second
