Selecting Streaming Format and Bitrate.
Depending on local conditions and type of connection (Wi-Fi, Ethernet or 4G LTE) different streaming
formats and bitrates may be chosen to provide smooth streaming and pleasant viewing experience.
Keep in mind that slightly lower resolution but stable stream is always preferable vs. higher resolution
video, which stops and breaks abruptly.
It is always good idea to check you connection speed with Speed Test tools utilizing smart phone,
tablet or PC prior to start streaming. Check Upload speed, not Download since you will be uploading
(pushing) video to the server.
JVC camcorders offer wide range of streaming bitrates from as low as 0.2 Mbps for Skype-like video to
broadcast-quality streaming @ 5-8-12 Mbps.

5 8 12
480x270p
720x480i

The rule of thumb is to select streaming bitrate at approximately 50-65% of available upload speed.
Depending on type of video: low motion (interview, focus group, “talking head” etc.) or high-motion
(sports, action, stage) chose 480i or 720p/1080i formats.
