The Large Option for Sending Video Images Is Unavailable

MORE INFORMATION

When your computer is configured to use a video capture adapter that is not registered with NetMeeting, NetMeeting queries the video capture adapter for its default capture frame size. The default capture frame size is usually 160 X 120 or 320 X 240. NetMeeting uses this default capture frame size to generate all the NetMeeting frame sizes. These frame sizes are:

   Small  - 128 X 96
   Medium - 176 X 144
   Large  - 352 X 288
				

If the default capture frame size is 160 X 120 (or close to it), NetMeeting enables the Small and Medium options because NetMeeting can create the small size by cropping from 160 X 120 to 128 X 96, and create the medium size by black banding the 160 X 120 images to 176 X 144. The large size is disabled.

If the default capture frame size is 320 X 240 (or close to it), NetMeeting enables all the image size options because NetMeeting can create a 160 X 120 image by down-sampling a 320 X 240 image. NetMeeting then uses the same techniques it uses with the 160 X 120 default frame size to generate the remaining NetMeeting frame sizes. Overall NetMeeting video performance can be slow because of the overhead of capturing video in 320 X 240 mode.
