Windows Media Encoder Page

1/29/2010The Big Picture of Creating and Using Videos for Teaching & Learning - (Jan. 2010) how to create, prepare, and post videos -- pretty easy!

Windows Media Encoder is a powerful tool for teachers (or anyone producing content) who wishes to capture audio and video content from a computer screen, or screens, for later playback using Windows Media Player. Windows Media Encoder is a free download from Microsoft.com (once installed it may be found in Start|Programs|Windows Media). For playback, Windows Media Player is pre-installed with windows (or a free download).

Handout from my talk at the ICTCM Conference (Boston, 2/17/07) titled Using Windows Media Encoder to Enhance Mathematics Teaching and Learning: This May be the Missing Link

Sample Videos *

The following are .wmv (windows media videos) which, upon clicking, should open up in Windows Media Player.

My Test Videos

With Media Encoder you have two choices which effect file size and video quality: (a) how much of the computer screen to record (one window, section, entire screen) (b) quality of the video (low, medium, high). I was curious as to how much difference there was (in file size and video quality). I made seven one-minute (approximately) videos. For each video the file size, length (min:sec), and KB/second are shown. Click to view the video quality.

A few things I noticed:

Note: I have found that the quality of the video playback does vary from computer to computer. What may look very good on one machine, may not look as good on another. This may be due to the quality (and age) of the computer's video card or other factors.
