Blitzz Video uses variable bitrate 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. The actual bandwidth consumed will vary based on network conditions.
|Media Quality||Data transfer rate (kilobits per second)||Data transfer rate (GB per minute)||Typical call duration (5 Minutes)||Network|
|Lo-res Video (240x180) + HD Audio||200 kbps||0.0015 GB / min||7.5 MB||WiFi / 3G|
|SD Video (640x480) + HD Audio ||540 kbps|
0.00405 GB/ min
|20.25 MB||WiFi / LTE / 3G|
We recommend a minimum of 540 kbps (up/down) bandwidth for video calling with a decent experience.
