BrazenLive Video Broadcasts provide live video broadcast and screen sharing capabilities in your event. Group Video allows you to hold a live video/audio chat between booth hosts and participants, with up to a total of nine people at a time. One-on-One (1:1) Video and Audio Chat gives Representatives the option to transition from a text-based conversation to a private video chat with an event Candidate/Attendee.
All three features use Vonage technology, which is built using WebRTC. All multimedia traffic is routed through Vonage media servers; peer-to-peer connections are never used. Hosts, Presenters, and Representatives see incoming video in real time.
If you are troubleshooting your audio and video connection, first review Troubleshooting Audio & Video for Live Video Features in Brazen, then review the technical requirements below.
Brazen video services require access to each user's camera and microphone. Hosts and Presenters must enable access to their device's screen to share a presentation. Read more about enabling camera and microphone permissions on a PC and Mac. Read about screen sharing permissions on a Mac.
Brazen is only compatible with the latest two versions of the supported browsers. Please update your browser before joining a Brazen event.
Browsers supported by the Brazen platform include:
- MS Edge
- Older, non-Chromium versions of Microsoft Edge (prior to version 79) do not support screen sharing capabilities.
- Google Chrome (desktop and mobile)
- Safari (desktop and mobile)
- Screen sharing capabilities are limited on Safari.
A minimum of 350 kbps available bandwidth per stream is recommended for the lowest acceptable quality on Brazen video services. A stream is any incoming or outgoing source.
1:1 Video and Audio Chats
1:1 Video and Audio Chats consist of two streams, one from each person in the chat.
The lowest acceptable video and audio quality in 1-on-1 Video and Audio Chats requires at least 700 kbps available bandwidth from each participant to handle the incoming and outgoing video and audio. Fair quality video and audio chats need 1000 kbps (1 mbps) or higher available bandwidth. For high quality sessions, we recommend 3 mbps or higher available bandwidth.
BrazenLive Video Broadcasts & Group Video
At least 350 kbps available bandwidth per stream is recommended for the lowest acceptable quality for BrazenLive Video Broadcasts and Group Videos.
For example, a BrazenLive Video Broadcast with a presenter in the Host role, an additional Presenter, and a shared screen consists of 3 streams. In this scenario, each Presenter should have at least 3x350kbps available bandwidth.
The recommended bandwidth for fair video and audio quality is 500 kbps available bandwidth per stream. In this case, 3 people in a Group Video would need at least 1500 kbps available bandwidth.
For high quality sessions, we recommend at least 1 mbps available bandwidth per stream.
Users' browsers must be able to reach the following domains directly, in addition to the standard Brazen whitelisted domains:
Brazen Video Services automatically negotiate the best possible route for multimedia traffic. Open the following ports:
- TCP: 443
- UDP: 3478
Optionally, Vonage recommends opening the following ports to ensure the best audio and video experience:
- UDP range: 1025-65535
WebSockets are recommended, but not required, for Brazen video services. Certain metadata, such as the other users' connectivity status, is relayed over a WebSocket connection and is lost when this connection type is blocked.
All three features work as normal through transparent proxies. Proxies which inspect and/or alter traffic may interfere with video and audio capabilities. Talk to your Brazen Account Manager and company IT department to determine the best practice.
Vonage Video API service hosts Brazen audio and video features. Vonage requires you to whitelist all of the following IP addresses:
