In order to provide an optimal viewing experience for your audience, please ensure you are presenting from a reliable internet connection. As a minimum bandwidth, we recommend 6Mbps (megabits per second) download / 2Mbps upload.
Your download performance impacts the connectivity between you and your view of the BrightTALK presenter screen i.e your fellow presenters' video feeds (if you are not the only presenter), any screen-shares that are initiated, and visibility on audience questions.
Your upload performance impacts the quality and consistency of the audio / video feed that you are broadcasting to your audience (and presenters) via BrightTALK.
In real-time video applications, clients must be able to exchange audio, video, and other media with one another with as low latency as possible. Below are the protocols and ports through which Talks will attempt to establish a connection for media exchange, in order of preference.
Using TURN-TLS on port 443 adds the highest amount of latency to the transmission of media. It is a last fallback if other communication methods are blocked.
| Protocol | Port Range | Preference |
| STUN and UDP/TLS/RTP/SAVPF | 10000 - 60000 | Ideal connection |
| STUN, TURN-UDP | 3478 | A little bit of latency |
| TURN-TLS | 443 | More latency |
It is strongly recommended that you carry out a practice webinar in advance of presenting to your live audience. This practice should be carried out on the same internet connection that are you are intending to use on the live day. If you have a colleague available to join you for the practice, they can confirm the quality of your audio / video. This will give you an indication of how your internet connection is likely to perform on the live day.
