Programmable Video uses variable bit rate codecs for all communication. This means that the quality of a call will be dynamically adjusted to adapt to changing network conditions, and therefore the bandwidth usage will vary throughout the duration of the call.

Use the following table as a guide for estimating data rates for common use cases. Actual bandwidth consumed will vary based on network conditions.
