What version of Premiere Elements, what computer operating system?
With versions with SmartSound, setting SmartSound duration before dragging to Timeline was an option.
With versions with Music Score (SmartSound concept but not Smart sound), you drag the Music Score to the Music/Soundtrack and go through
a. Creating Score progress dialog
b. Conforming Audio progress dialog
c. Get a Score Properties dialog with options for Intensity and check box for disabling or enabling "Fit Entire Video"
You can make Music Score duration changes at the Timeline level if, after clicking Done to the Score Properties dialog, you need to adjust the Music Score duration.
Please consider and give details.
