Technical Requirements to Go-live on Events

The following are the technical specifications for hosting or attending an event on Zuddl. This includes system, browser, and connectivity specifications for minimum, recommended, and best event experience. This delineates the specifications for attendees and organizers as well.

System Specification

Level Processor Memory Support
Minimum (for attendees) Quad-core 8GB
Recommended (Minimum for Organizers) Octa-core 16GB Smoother experience for a stage with 4 speakers
Best experiences Octa-core >16GB HD Video and 4+ stage speakers
Note:
Zuddl events are best experienced on a laptop or a desktop. Nevertheless, you can also attend sessions on your mobile devices with limited interactivity. If you are an organizer, we strongly recommend that you use a laptop or desktop to host your events on Zuddl.

Supported Browsers

Zuddl works well with the latest version of Chrome (76 or higher). Zuddl relies on H.264 codec for supporting WebRTC-based routing. Upgrade to the latest version of Google Chrome.

Highly Recommended

It is highly recommended that you use your browser’s update functionality to update to the latest version.

Browsers

Browser Minimum version Recommended version Best experience Platform
Chrome (Recommended) Version 76 or higher
v.94 macOS10+Windows 7+
Safari Version 11 or higher

Browser Limitation
In some versions of the Safari browser, the audio output/speaker selection option shows only System Default Speaker Device in the list.

Network Requirement

With all the interactivity the platform offers, having a stable internet connection with adequate speed becomes essential for an optimal in-meeting experience. If you are an organizer, ensure that your browser allows you to stream media.
You can run a speed test to know your network speed.  If you’d be using the same network for your event,
Zuddl checks for your internet speed, browser compatibility, audio, and video requirements upon entry for a seamless experience throughout.

The required internet speed based on the experience is shown in the table below:

Connectivity

Property Minimum Speed (Mbps)) Recommended (Mbps)) Best Experience (Mbps)
Uplink Speed 4 8 >20
Downlink Speed 3 8 >20
For organizers, the minimum internet speed is <recommended> onwards.

Upload Speed without Screenshare

Speed (Mbps) Resolution
3 - 5 480p
10 and above 720p
20 and above 1080p (only on request basis)

Upload Speed for RTMP Out

Speed (Mbps) Resolution
5 - 8 480p
10 and above 720p
20 and above 1080p
The above table data is the same for the required upload speed with screen share.

Download Speed

Name No. speakers
4 Mbps 4
6-7 Mbps 5 - 9
20 Mbps 10

Bitrate (in Kbps)

Bitrate (kbps) Resolution FPS Bitrate With Screenshare (Kbps) 2
400 - 800 360p 30 2000
600-1200 480p 30 900-1800
260 - 520 360p 15 390 - 780
The above table is created keeping the number of speakers as 1. As the number of speakers increases the bitrate gets multiplied by a factor of the number of speakers.
FAQs
  • I am using the latest Google Chrome version on a device that meets the specification. Why is the video lagging?
    • On all AMD-based and some Intel-based devices, Google Chrome uses the H.264 codec which may cause the video transmission bitrate to be lower than the set value. As a fix, you can disable hardware acceleration.
