If you left a marker or something else somewhere up to the right, that may be keeping things longer than desired - delete anything that's beyond your 7.5 minutes.

Hit the "Go to End" button.
As long as it stops at the 7.5 min. mark, you're OK.
If it doesn't, do as has been suggested and delete anything unnecessary.

Ok, you are all right, in that it is "really" empty and it doesn't really affect anything other than how the timeline zooms and how the job opens from the beginning. I like to have it so when I open the timeline initially, that it be roughly sized according to the length of the video. As it is now, when I open the timeline, all my edited content is squeezed up teeny tiny at the front of a two hour timeline. I just thought it would be nice to lop off all that unused space but apparently that's not possible. Only a small deal. Good to know that I didn't miss anything obvious. Appreciate your help.

Just had a fiddle to check this out. Started with a 3 min project, and the timeline never zoomed out more than that 3 min. Extended it it to 2 hours, the timeline obviously expanded, but then deleted everything beyond 3 mins, and the timeline did not shrink back to 3 mins, it stayed 2 hours long, even though there was nothing beyond 3 min.

BUT .... once I saved the project and closed it, when I reopened it, the timeline was back to a max of 3 min - is your experience different to this?

Peter, that has always been my experience.

At start-up of program my time line is always 2 minutes. When I open a project it stays at 2 minutes unless the project is larger then it will default to the length of the project. While Vegas is running it remembers the length of the time line from the previous project. It continues to do this until I exit Vegas. The it goes back to the 2 minutes again.

Peter,

When I saved my project and reopened it the timeline became 8 minutes long. What I had done before was delete all audio video files on the timeline after 7.5 minutes but I had left 3 or 4 markers. The markers were what was causing the timeline to remain at 2 hours long. So, thanks for solving that little annoying problem for me.
