Why is video playback so choppy?

If your video playback isn’t smooth as margarine, here are some things you can try:

  • Try letting the video buffer before you view it.
  • Close other browser tabs and windows. This can make a huge difference!
  • Make sure you have either the latest version of Flash running on your computer, or use a browser with native HTML5 support.
  • Switch to another browser to see if that helps.


What is video buffering, and how do I do it?

Buffering is a way of preloading the videos you watch so that fluctuations in your Internet connection don’t cause choppy playback.

When you play a video, a light gray bar will advance in front of the playhead, showing you how much of your video has been buffered. Your playback should be smooth as long as you’re viewing your video within the light gray buffer region.

If you’re experiencing choppy playback, pause the video, allow the video to buffer for a few moments, then try playing your video again!

If you’ve asked me to clear cache on a page or the browser. How do I do that?

To clear the cache in your browser hold down the shift button and reload the page. This method resets the information about the page that’s stored in your browser.


Do I need a fast Internet connection for HD videos?

Most residential cable and DSL connections should be more than adequate. If HD feels slow to load, try turning off any background applications that could be using up bandwidth. Or push the play button in the player and then pause to let the video buffer before viewing.


What is hardware-accelerated decoding, and how do I disable it?

All videos need to be decoded in order to be viewed. In other words, the data within a video file is interpreted and rendered as sound and images for playback. On Vimeo, videos are decoded using either your browser’s native decoding technology or Adobe Flash.

Hardware-accelerated decoding means that your computer’s hardware is used in addition to your browser or Flash to decode the video. Depending on your particular hardware configuration, this may affect the look or sound of video playback on Vimeo (and across the wide world of the Internet).

When troubleshooting playback issues, you may want to try enabling or disabling hardware-accelerated decoding. How you do so will depend on whether your browser uses Vimeo’s Flash or HTML5 player. (FYI: Not all browsers or operating systems utilize hardware-accelerated decoding.)

HTML5: Visit your browser’s support page to learn how to disable hardware-accelerated decoding for that particular browser.

Flash: Follow the instructions here.


Which version of the video player am I seeing?

There are two different versions of the video player: Flash and HTML5.

The version of the player in use will depend on your browser, the type of file you are viewing, and whether you are viewing it on-site or as an embed. The following are general guidelines as to which player you’ll probably be using:

Firefox (any version): Flash
Safari (5+): HTML5
Chrome (any version): HTML5
Opera (any version): Flash

Firefox (21+): HTML5
Chrome (any version): HTML5
Internet Explorer (11+): HTML5
