Mixing Aspect Ratios on Codian Bridges

I work for an organization with six Codian bridges and hundreds of Tandberg/Cisco conferencing units. These units range in age from several years old to brand new.

Our organization does hundreds of video conferences per week, and one issue we've run into as of late is when HD codecs are added into the conferencing network. Basically all our bridges have to be set to "4:3 Resolutions Only" or else 4:3 participants are stretched out to 16:9. However, 16:9 participants are then cut off on the sides, which is fine for camera shots but computer images/presentations are then restricted.

Is there some setting we are missing that will allow both 4:3 and 16:9 resolutions to both appear in a conference as they should? Is there a way to tell the system to letterbox a 16:9 image within a 4:3 frame for those participants who are still only able to receive a 4:3 signal? Or a way to force 4:3 images to remain 4:3 when the bridge is set to either "16:9 resolutions only" or "allow all resolutions"?

Have you tried the 4:3 for widescreen display or allow all resolutions setting for Transmitt resolution on the bridge confernce settings

4:3 for widescreen displays only squeezes everything into a 4:3 image for all involved. Even existing 4:3 transmissions are altered within the existing 4:3 window.

Allow all resolutions and 16:9 resolutions only behave the same way. Any 4:3 image is stretched to 16:9.

HI Chuck,

This should work fine as the MCU it's designed to mix 4:3 and 16:9 participants.

Can you please try to set :

Transmitted video resolutions : "allow all resolutions"

Video transmit size optimization : "dynamic codec and resolution"

To see if this helps ?

Regards

"Dynamic codec and resolution" is what the bridges are always set to. Changing the resolution to "allow all resolutions" stretches any 4:3 image to 16:9.
