All NIEHS live webcast events and video on-demand content are securely streamed over HTTPS through port 443.

Please Note

Volume Issues
If you are having volume issues, please ensure that the volume is not muted on your computer or device and that the volume is not muted in the NIEHS video player. To check the volume in the video player during computer playback, please hover your mouse over the video window and click on the white volume icon in the lower right hand corner. Adjust accordingly.

Playback Issues
By default, the NIEHS video player and streaming platform are designed to automatically decrease or increase the quality of a live webcast stream depending on a user’s bandwidth in order to provide the smoothest possible playback. If you are having unexpected bandwidth issues or would like to manually control the quality of the live video stream yourself, please click on the white HD button in the lower right hand corner of the player. Select a lower or higher quality stream that best suits your preference and current bandwidth allocation.
