● High Profile - Endpoints that support H.264 High Profile connect at these minimum threshold bit
rates.
In Sharpness mode
In Motion mode
Although the default minimum threshold bit rates provide acceptable video quality, the use of higher bit rates
usually results in better video quality but will require more resources.
The Base Profile and High Profile sliders operate in the same manner in Sharpness and in Motion.
Video Resource usage is affected by the Resolution Configuration settings. The lower the line rate threshold
set for a certain resolution the more resources will be used to connect that participant (as a higher resolution
will be used).
