Two higher quality, intermediate video resolutions replace the transmission of CIF (352 x 

288 pixels) or SIF (352 x 240 pixels) resolutions to endpoints that have capabilities between:
•

CIF (352 x 288 pixels) and 4CIF (704 x 576 pixels) – the resolution transmitted to these 

endpoints is 432 x 336 pixels.

•

SIF (352 x 240 pixels) and 4SIF (704 x 480 pixels) – the resolution transmitted to these 

endpoints is 480 x 352 pixels.

The frame rates (depending on the endpoint’s capability) for both intermediate resolutions 

are:
•

In MPM Mode  – 25 or 30 fps.

In MPM+ / MPMx Mode – 50 or 60 fps.
For information about setting system flags, see "Controlling Resource Allocations for Lync
