A scene's duration can be driven by one of four options:
End of duration of placeholder (video or audio)
End of duration of placeholder plus a number in seconds
Original scene duration
Duration can never be longer than the original scene duration.
In order to edit the time, click on the Edit button next to the scene duration at the top of the right hand panel in the interface.
The 4 available options can be chosen:
Shortening duration by using the placeholder asset's duration is available only for video or audio assets, since only those assets have a duration.
If color or image is used, the duration of the scene will be the maximum duration.
