Video Input Connector [1..5] Quality

When encoding and transmitting video there is a trade-off between high resolution and 

high frame rate. For some video sources it is more important to transmit high frame rate 

than high resolution and vice versa. This setting specifies whether to give priority to high 

frame rate or to high resolution.

Requires user role: ADMIN
Default value: Connector 1, 2, 5: Motion   Connector 3, 4: Sharpness

Value space: Motion/Sharpness

Motion: Gives the highest possible frame rate. Used when there is a need for higher 

frame rates, typically when a large number of participants are present or when there is a 

lot of motion in the picture.
Sharpness: Gives the highest possible resolution. Used when you want the highest 

quality of detailed images and graphics.

Video Input Connector [1..5] OptimalDefinition Profile

This setting will only take effect if the corresponding Video Input Connector [n] Quality 

setting is set to Motion. 
The optimal definition profile reflects the lighting conditions in the video conferencing room 

and the quality of the camera. The better lighting conditions and the better quality of the 

camera, the higher the profile. In good lighting conditions, the video encoder will provide 

better quality (higher resolution or frame rate) for a given call rate. Generally, the Normal or 

Medium profiles are recommended. However, when the lighting conditions are very good, 

the High profile can be set in order to increase the resolution for a given call rate.
Some typical resolutions used for different optimal definition profiles, call rates and 

transmit frame rates are shown in the table below. The resolution must be supported by 

both the calling and called systems. Use the Video Input Connector [n] OptimalDefinition 

Threshold60fps setting to decide when to use the 60 fps frame rate.

.

Requires user role: ADMIN
Default value: Medium

Value space: Normal/Medium/High

Normal: Use this profile for a normally to poorly lit environment. Resolutions will be set 

rather conservative.
Medium: Requires good and stable lighting conditions and a good quality video input. For 

some call rates this leads to higher resolution.

H.265 is preferred over H.264, and the maximum bit rate for H.265 is 3 Mbps. When the user sets a higher bit 

rate, the codec will still use H.265 at 3 Mbps as long as all codecs involved supports H.265.
