The quality of your live playback experience is largely dependent on the download speed you have from your ISP (Internet Service Provider) or mobile provider. Keep in mind that your overall Internet speed can vary depending on many factors.
This article discusses factors affecting playback quality, including internet speed, browser compatibility, firewall settings, and device requirements.

Desktop OS and Browser
In addition, we recommend using the following browsers and versions on Windows 7 or later or macOS Sierra (10.12.6) or later:
- Chrome 30+ (has automatic updates)
- Firefox 27+ (has automatic updates)*
- Microsoft Edge
- Safari 9+
*H.264 video (required for viewing Vimeo videos) is only supported in Firefox for Windows 7 and later. Firefox versions on Windows XP are no longer supported for playback.
To know about the supported browsers on mobile/tablet, refer to System Requirements for viewing, browsing, and apps.
Firewalls and whitelisted domains
Viewers should ensure the following ports are open on their network for playback:
- TCP/UDP 80 (HTTP)
- TCP/UDP 443 (HTTPS)
In addition, if your viewers are on a corporate network (office, university, hotel, etc.) that restricts access to certain websites or domains, they should have the following domains whitelisted:
- *.vimeo.com
- *.vimeocdn.com
- *.magisto.com
- *.akamaized.net
- *.cloudfront.net
Mobile devices
Mobile viewers can use Android (Lollipop) version 5.0+ or iOS version 12.4+.
⚠️ Blackberry and Windows phone users: You may still able to view Vimeo videos on devices that support HTML5; however, we do not test out our player in these environments and thus cannot guarantee support.
⚠️Samsung users: The Samsung Internet browser (all versions) is not supported for Vimeo Live. We recommend installing Chrome instead.
