Player Setup and Sample Videos

Player Setup

Make sure that the computer that you are using is set up correctly to play streaming video or audio. If you need to add a player to your system, you can get the free version of each player at the following websites.

QuickTime

http://www.apple.com/quicktime/download/

Select player version to download

Windows Media

http://www.microsoft.com/downloads/

Enter "windows media player" as the search text

Installing multiple media players on your system can be tricky. Adding a player can have side effects on players already on your system. For example, the default player for MP3s and CDs could get changed. Always retest players after installing a new player version.

Sample Videos

The following table provides links to various clips that you can use to test your streaming video player. There are three clips. Each has been encoded for different play-back speeds (Kilo-bits per second) and in different formats (QuickTime or Windows Media). On-campus, you can likely use any play-back speed option. Off-campus, you may want to start with the 56Kbs streaming versions.

QuickTime v6

Windows Media v8

 

If you are a producer of video and your viewing audience will be off-campus, you should try the 56Kbs slide versions. This approach gives you a quality audio signal with still pictures.
(The links work best using Microsoft Internet Explorer 5.0 or greater. Some files may not open properly if you are using an Apple Safari browser.)
