TED.com is optimized for the latest browser versions. If a talk isn’t playing, check that you’re using the most up-to-date version of your browser. As of February 13, 2017, TED uses an HLS-based player (as opposed to Flash) that’s built in-house.
The video player is designed to automatically adjust video quality based on your internet bandwidth. If you find that the video quality is poor, or that the video pauses too often, try checking your data connection strength or using a different browser.
We have found that many Windows users (including Windows 7, 8 and 10) have experienced problems playing TED videos due to an incompatibility with our TED.com video player. This usually manifests in lost audio.
Our engineers are working on a fix, but as a temporary workaround to watch individual talks, try the embed player version: https://embed.ted.com/talks/
Or, you might instead try downloading the talks to watch offline (our download article can show you how).
If none of the troubleshooting steps help, send an email to firstname.lastname@example.org with the following:
- Link(s) to the video(s) you’re having trouble with
- Results link from What's My Browser
- A description of the problem (the video won’t load, pauses or stutters, etc)
