Warpwire is a simple, user-friendly, media publishing solution that integrates with Duke's identity management system to offer NetID and group-based security. It was developed by the makers of Voicethread and is being offered to the Duke community as a production service starting in January, 2015.
Anyone with a valid Duke NetID can use Warpwire to publish media files.
Account setup in Warpwire is automatic when a valid Duke NetID holder logs in to Warpwire.
You can log in to Warpwire via https://warpwire.duke.edu. Click the yellow button that says Log in. You will be taken to the Shibboleth login page or to the main Warpwire application window if you already have a Shibboleth session open in your browser.
Warpwire currently supports videos, images and audio files A full list of currently supported file types can be found here: https://www.warpwire.com/support/playback/browser-requirements-and-file-types/
Warpwire uses Adaptive Bitrate Streaming and currently produces 3 different versions of each video you upload. When a user plays a video, Warpwire automatically delivers the highest quality version of the video the viewer's internet connection and CPU can support. This can change in real time, such that if a viewer experiences a temporary bandwidth glitch, Warpwire will automatically shift to a lower resolution version, and then back up if and when the issue improves. This is how Netflix and most other major online video providers deliver video. The three different versions of the video Warpwire produces have the following specifications:
- 360p - 640 x 360 @ 550 kbps
- 480p - 854 x 480 @ 1.5 Mbps
- 720p - 1280 x 720 @ 3 Mbps
- Viewing videos at 360p requires 1.0 Megabit per second
- Viewing videos at 480p (SD quality) requires 3.0 Megabits per second
- Viewing videos at 720p (HD quality) requires 5.0 Megabits per seconds
Test your network speed here: http://www.speedtest.net/ Latency To stream videos effectively via Warpwire's default method (currently Apple's HLS protocol), your network latency (sometimes called "ping") should be no greater than 150ms. Test your latency ("ping") here: http://www.speedtest.net/) Browser Requirements: See https://www.warpwire.com/support/playback/browser-requirements-and-file-types/
If your videos keep buffering (i.e., showing three moving dots on top of the video), test your network connection for bandwidth and latency via http://www.speedtest.net/). If your bandwidth and/or latency are close to our minimum recommended thresholds, switching the media libraries to Progressive Download may help. To do that, contact the OIT Service Desk (oit.duke.edu/help) if you own the Media Library or Libraries containing the problem files and provide the name and URL of the Libraries in question. If you are not the owner, contact that person (the person who shared the files with you) and request that they contact the OIT Service Desk to switch to Progressive Download or make other arrangements to share the file/s with you.
Please note that if you do not have a bandwidth of at least 1 Megabit per second, your best option may be to request that the owner of your Media Library or Libraries move the files to Duke’s box.com site where you can download the videos and view them on your local hard drive.

Warpwire content is retained in the system for five years.
Yes. File sizes for individual files is currently limited to 10GB per file.
There is currently no policy that sets any limit on the overall space a user or department may utilize in Warpwire.
In the Warpwire Share interface, you can search for and share with Individual Users or with Groups. For Individual Users, you can search by Name or by NetID. Group search currently only includes course groups and ad hoc Toolkits groups, and will be expanded later (date TBA) to include other types of groups, such as staff and administrative groups (i.e., all staff at the Law School). You also can share media with anyone on the web that doesn't have a Duke NetID.
