Can anyone point me to a document listing the recommended upload speeds for 720p or 1080p concert broadcasting?
This ultimately depends on three factors: your internet upload speed, the equipment you use, and the download speed of the viewers. We recommend at least 3 mbps upload when broadcasting with our built in broadcaster. If you are trying to push true HD with 3rd party streaming software via RTMP you’ll likely need more. It’s also likely the bulk of viewers will not be able to accommodate that large of a stream.
More equipment and a higher resolution stream doesn’t always mean better quality: if you keep it simple and take the time to check your sound and video properly, you’ll end up with the best results.
