Once you learn the basics of using the Composer you can start creating content.
The composer allows you to create interactive video and audio projects. There are a variety of options for creating interactive content. Before you can do so, you need to either connect two nodes, or add a audio file to your timeline. The video above shows you how to do so.
For a written explanation, read the following:
In order to create an interactive video project, you'll want to connect two nodes so a user can go from one video to the next. You'll do this by creating an exit flag on the timeline of the first node. Right click the timeline and press "New Exit Flag," this will add an exit flag to your timeline. We will cover editing this exit flag in the "Video and Hotspots" section of the support docs.
To create an interactive audio project, you'll need to have audio files uploaded to the CMS. When you've done that, you're on the composer, and you have a node on the canvas, you can right click the timeline and press "New Audio." This will create a new audio file on the timeline, to edit this audio file, you can read more in the "Audio and Hotspots" section.
