There are many choices to make when it comes to Webcasting: live vs. on-demand, audio vs. video, and more. So here are some of the questions you’ll need to ask yourself before deciding which way to go.

• Live vs. on-demand. Although broadcasting an event live may be necessary for breaking news or a corporate announcement, it is also much more expensive than broadcasting it later. When, where and how will your audience access the broadcast? Your flawlessly (and expensively) produced broadcast can fail if no one is watching it.
• Live vs. edited highlights
  Conferences contain lots of down time that isn’t boring when you’re on site but which don’t translate well via broadcast. That’s why you may be better off offering edited highlights. For example, present each conference speaker as a separate link to their presentation, with background and audience reaction. Viewers can then exercise more control, viewing in the order they prefer. This also gives them the broader context of the event.
• Audio and/or video. An audio webcast is much less expensive to produce than video, which involves onsite production costs for crew, lighting, and equipment. So you need to decide whether an audio Webcast is sufficient or whether your audience needs to see full video of the speaker with live integration of speaker support. Keep in mind that a video Webcast also demands higher bandwidth from Web users. So before making these crucial decisions, find out your audience's bandwidth, firewall or VPN limitations and Web usage habits.

Very few Web-based meetings need to be live only. Use the fact that the Internet is a 24/7 medium to your advantage. Increase attendance (and attentiveness) by allowing remote attendees to view at their convenience.
