The Video Demo recording mode allows you to create a video file by capturing the onscreen actions. A Video Demo recording project actually is a big Full Motion Recording. In the 2019 release of Adobe Captivate, you also get the ability to record your webcam feed alongside the screen capture.
A Video Demo project is quite different from the other projects you have worked on so far. Because a Video Demo project can only be published as an .mp4 video file, no interactive objects can be included in such projects. In other words, it can only be a demonstration. Because a Video Demo project is based on a single big video file, there is no slide or Filmstrip panel in a Video Demo project. This makes Video Demo projects particularly suitable for upload to an online video hosting service, such as YouTube, Vimeo, or Dailymotion.
