What resolution does Warpwire use for delivering video?

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

What are the minimum technical requirements for using Warpwire?

Network Speed:
  • 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.

My Warpwire videos keep buffering. What can I do to improve performance?

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.

When would I use Warpwire vs. YouTube?
