In a default just:live setup each clip in the timeline does not start automatically when an earlier clip finishes. Instead, just:live goes back to the default output defined by your system administrator (black or live signal pass through).
Each clip waits at the CTI line for you to issue a play command for it to start.
Thus, if you would load five Video clips into the timeline you would also have to issue five play commands to play them out – unless you define Finished Actions.
A play command is only valid if nothing is currently playing and there is an element waiting at the CTI line to be played out.
To play several Elements with a single play command:
Select the Elements which should play consecutively in the Timeline or Workbench.
Change the Finished Action attribute for the selected Elements in the Inspector to Play Next.
Start the playout.
