This article will outline how to troubleshoot issues you might be experiencing.
We recommend you use Google Chrome. Safari, Firefox and Edge are supported as well but Chrome will perform best.
Which Browser To Use
In order of preference, here are the best Browsers to be on when using Bevy Virtual or Bevy Virtual Conference
You are a speaker or sharing Video and Audio
You are taking part as an attendee and watching the session
- Is your browser up to date?
- Are you using any browser extensions?
- 'uBlock Orgin'
- Have you tried other browsers like Safari or Firefox?
- If you have persistent issues only in Google Chrome specifically, you may try uninstalling Google Chrome and retrying.
- Does it happen in other browser apps in Chrome, like Google Meet?
- Are you on a VPN? Try disconnecting and refreshing your browser with a hard refresh (ctrl + shift + R).
- Full uninstall Chrome (https://support.google.com/chrome/answer/95319?co=GENIE.Platform%3DDesktop&hl=en) and reinstall

If you're having connectivity, software, or hardware issues, you can run a pre-call test here: https://tokbox.com/developer/tools/precall/
If you see all green results, please follow the below basic troubleshooting steps.
Audio & Video troubleshooting
- If you are not able to hear the session, try refreshing the window.
- If you still cannot hear the session, ensure you are using Chrome, click on the lock icon in the left of the URL bar, and ensure the Sound is coming out of the correct speaker.
- You might also check to ensure you haven't muted the tab.
- If you are using Chrome, you may visit site settings Settings > Site Settings > View permissions and data stored across sites > Site URL > switch Microphone to ‘Ask,' restart Chrome
- Ensure the correct camera is chosen if you click the carrot icon besides the Camera icon
- If you are using an external camera or microphone and do not see the option try unplugging and resetting on your device.
- Ensure that you are NOT using a virtual background app/extension like Snap Camera or Mmhmm.
- Disable your browser extensions.
- If you are still experiencing poor video quality, it is likely a result of poor internet connection. Bevy Virtual automatically scales up and down per user depending on the local internet connection. If you have a poor connection, the platform may turn off others' video for your view, or turn off your video for others so they will not see you to preserve bandwidth for a strong audio connection.
- Windows Users with Built-In cameras: Some windows machines can't use the camera in more than one app at the same time, so Zoom + Bevy won't work.
- Scale down resolution if you’re seeing buffering issues. You can do that throught he video icon here in the corner of the Stage player.:
Screen sharing/MacOS Permissions
- If you're having trouble sharing your screen in Presenter Mode, you may need to tweak settings on a Mac computer. This is common for those that are using Bevy Virtual for the first time on a Mac computer.
- Click the Apple logo in the top left corner of your screen
- Select System Preferences
- Locate Security and Privacy
- Toggle the Privacy tab
- Scroll down to "Screen Recording" - enable this for your browser - Chrome, Firefox, or Safari.
- Quit your browser and reopen the session. You should then be able to screen share.
- If you are playing a video with sound through screenshare, ensure you are not using headphones. The audio will come from the microphone detecting sound out of your computer speakers.
Viewing the session
- If you are having trouble viewing the session or participating in chat, refresh your browser window and re-enter the session.
- Bevy Virtual is an in-browser web application; this makes events more accessible and does not require any software download. As a result, browser performance will affect your experience on Bevy Virtual. To maximize the experience, try to keep minimal tabs running, and minimal application windows running on your machine while you are attending a Bevy Virtual session.

To change your name or profile picture

Bandwidth Requirements / Recommendations
Video quality dynamically adjusts based on the strength of a user's network connectivity. This is done by the Subscriber sending feedback packets to the publisher that say "My network quality is at 'x' level. Please adjust your published video bit-rate to accommodate my current bandwidth". The faster and more stable a Subscriber's broadband connection is, the better the video quality it will request.
This mechanism works well until a certain point. If a Subscriber's bandwidth drops below a certain threshold, or if a Publisher has very little bandwidth to upload video, behavior can be unpredictable. Video may be choppy, audio may have artifacts, and the connection could be dropped.
We recommend a minimum dedicated 350kb/s down per downloaded stream, as well as 350kb/s up per uploaded stream to maintain a stable video connection.
For various resolutions and quality combinations, the bandwidth requirements are outlined below.
- Excellent - None or imperceptible impairments in media
- Acceptable - Some impairments in media, leading to some momentary disruptions
