When setting up your presentation you must select a presentation type. Below are three options:
Live - When you are running a live webcast where the speakers are not pre-recorded and the audience will be attending at a specific time.
Simulive - When your speaker(s) have pre-recorded their audio/video and the audience will watch the webcast in sync on a specific date/time.
On Demand - The most common use case is when your Live or Simulive webcast has concluded and you want your audience to be able to watch the webcast at anytime.
