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.
