Video Conferencing

« Audio Conferencing - VoIP | Main | Desktop - Application Sharing »

As a presenter you can send live video to meeting attendees.

If more than one camera is attached to your computer, you can also select the video camera you want to use. All attendees can view live video without having video equipment installed on their computers.

While sending live video during a meeting, you can control the quality of the video image and the resolution or size of the video image to adjust video output.

64x48

128x96

176x144

352x288

To control the quality of the video image, you have to specify a rate of 0 to 15 frames per second. A higher frame rate produces faster video, but uses more resources on your computer and bandwidth for your Internet connection.

Available frame sizes go from thumbnail sized 64x48 pixels (requiring about ISDN line speed or around 65 Kbps), to large size of 352x288 (400-500 Kbps). In between you can set your video window at 128x96 or at 176x144 (it requires approximately 250 Kbps).

In WebEx the video facility is set-up so that the video stream is shown only when the presenter decides to show it by clicking on the Video tab. If individual participants click on the Video tab during a presentation, while the presenter is not broadcasting her video feed, they will see a frozen image of the presenter video.
