What about Presentation Capture?
Allen Hopkins, 14 Nov 2002
Last updated: 16 Nov 2004

Presentation Capture is fairly complex, see the Netshow page in the Video GSRC Workgroup for details.

The basic idea is that we should be able to capture presentations for later broadcast. This is different from real time video conferencing in that the presentation is stored on a video server and broadcast on demand.

An example can be found at http://www.gigascale.org/pubs/talks/2002/berkeley/ but you must be a GSRC member to view the talk.

Types of captures

Audio only

Record an audio file.

Audio and Video

Record a streaming media file or an mpeg

Audio and synchronized Powerpoint slides

Audio, Video and synchronized Powerpoint slides

This is fairly tricky, but it is what we do for the GSRC Workshops Currently, we use NetShow, see the Netshow page in the Video GSRC Workgroup for details.

Requirements

Any solution must:
  • Run under Netscape - Powerpoint 2000 has a video capture feature that does not work under Netscape, the html files that are exported use dhtml, which is not displayed properly under Netscape Communicator
  • Run under Linux - Many students use Linux
  • Be easy for students to set up and operate
