Use the Timeline in Studio to organize the Live Camera Sources and Media Assets in the order you'll be using in your broadcast.
The Timeline lives at the top of the Socialive Studio interface:
When you have all the Live Camera, Guest Broadcaster, and Media Asset sources available, bring a source or asset into the Timeline by clicking and holding, then dragging to the Timeline:
When pulling a Live Source into the timeline, choose its desired Audio source by clicking the microphone at the top right of the source's thumbnail in the Timeline:
After you've loaded the Timeline sources, you can rearrange by dragging them back and forth:
Once you start the broadcast, a timer displaying the broadcast's elapsed time will be in the right panel, you'll have the option to End the stream at any time on bottom-right, and in the Timeline you'll know which source is live based on the yellow outline.
Preview the next source by clicking it once in the Timeline. A green outline will generate around the source, and the source/asset will come up in the Preview window underneath the Timeline:
Take that source LIVE by pressing the "Apply Changes" button in the top-right section of the Preview area:
Alternatively, if you're confident the next source you want to switch to looks good, you can take it live by double-clicking the source in the Timeline:
If a pre-recorded video asset is live, you will see a gold status bar below the video. This indicates how much of the video asset has elapsed, and how much time until the next Timeline source will be live:
You can choose to have a pre-recorded video asset play on loop by pressing the white "Loop" icon of a video asset in the Timeline:
Remove any source from the Timeline by clicking the "Trash" icon of the source in the Timeline.
