Browsers and system requirements

We strongly recommend keeping your system as up to date as possible. Browsers and operating systems are constantly releasing bug fixes, security updates, and improvements.  Using the latest browser version can always help.

Our live Q&A events use Vimeo Live and playback software. 

Playback:  the system supports playback in browsers that can decode H.264 videos in an HTML5 player. Due to rising security vulnerabilities, playback does not support Flash. If you’re using an older browser, or system, you’ll need to upgrade to continue watching these playback videos.

Here is a list of supported browsers/versions:

  • Chrome 30+ (has automatic updates)
  • Firefox 27+ (has automatic updates)*
  • Internet Explorer 11*
  • Microsoft Edge
  • Safari 9+ 
  • Android (Lollipop) version 5.0+
  • iOS version 9.3.5+

*H.264 video (required for viewing playback videos) is only supported in Firefox for Windows 7 and later. Firefox versions on Windows XP do not support playback. 

*Older versions of Internet Explorer (IE 10, 9, 8, etc) that lack support for the TLS 1.2 protocol and HTML5 cannot be used to play playback videos. As of January 12, 2016, Microsoft has stopped releasing updates to older versions of IE. (Microsoft's official statement on IE support can be found here)

The video player operates in a wide range of operating systems, but there is no guarantee of full functionality on systems that are not being supported by their proprietors.

Microsoft has ended support for Windows XP and Windows Vista. 

Sierra (v. 10.12.6) is being supported until end 2020. Earlier versions of MacOS (El Capitan, Yosemite, Mavericks, etc) are not supported. 

⚠️ Blackberry and Windows phone users: You may still able to view Vimeo videos on devices that support HTML5; however, playback videos are not tested in these environments and thus cannot guarantee support.

 

Live: Similar to uploaded videos, playback for live events is supported on any setup that supports H.264 videos, HTML5, and Media Source (specifically required for our adaptive streaming system). Please see our supported systems for playback above, with the following exceptions:

  • Internet Explorer 11 on Windows 7 and earlier is not supported for Vimeo Live
  • The Samsung Internet browser (all versions) is also not supported for Vimeo Live. We recommend installing Chrome instead. 

 

Internet connection requirements

Playback requires minimum stable download speeds of 500 kbps or faster in order to view lowest quality, SD 240p. Since bandwidth tends to fluctuate for a number of unforeseen variables, we always recommend you use a dedicated Internet line of 5 Mbps or faster to stream and download high quality videos on the Internet. For optimal performance, a hardwired connection via Ethernet is best, but if you prefer to use WiFi, be sure that your router is configured correctly and that your network is not being shared with other devices (this can limit the starting speeds you pay your ISP for).

Not sure what speeds your device is receiving? Visit https://testmy.net/download (on mobile or desktop) for an estimate.
