When doing a Web conference you will want to make sure that the video is captured for playback at a later date. This can be done by either having a camera man record the footage to mini DV tape and then edit it later or captured in real time to a windows media file.
You can then store that file on a Web server and supply anyone a link to the file to watch anytime. Often times when recording and capturing, there can be picture quality loss. Make sure you do a trial run and adjust the lighting and features so you achieve the best looking picture possible during the Web conference.
