If you create online instructional content incorporating Quicktime video, here is a technique you should learn. Quicktime allows a text track. This track can serve several purposes. The one I find most intriguing allows the text track to trigger HTML commands (or JavaScript) matched to exact frames in the movie. When used in this fashion, the text track is called an HREF track. A very useful application of this technique involves the presentation of a series of HTML pages within a frameset (see image below) matched to frames in the video. We are attempting to use this technique to offer text comments keyed to specific moments within short video segments of classroom behavior . In the image below (generated using screen capture), the video plays in the left frame and the series of comments appear in the right frame.
The Apple web site offers a tutorial explaining this technique.
