Adjust the Tempo to Fill a Length of Time

There is one other extremely clever method of setting up the tempo of a project. Say you ve composed the perfect background music for a thirty-second commercial spot. The only problem is that the music runs for thirty-five seconds at 120 bpm. Speeding up the tempo will make it run faster, but how much do you need to increase the tempo Guessing and experimenting will eventually get you the right answer, but ACID has a feature that lets you automatically adjust the tempo using just one marker. 

To match the project tempo to a length of time, do the following  

Position the timeline cursor at the desired length of time. 

Right-click the marker and select Adjust Tempo to Match Cursor to Marker. 

In this example, a 15-second project is shortened to be of the same duration as a 12-second piece of video.
