I had a long tutorial that I cut down through editing. The timeline did not decrease in size though, so I made editing a bit tough to do. How do you have rid of the all the extra timeline space, so just the cut-down media shows on the timeline?
Once you can see all the media on the timeline, you may see you have blank spaces with no media where you have cut sections out. If this is the case, you'll need to remove these blank sections. You should be able to do this by using Ripple Delete. Hope this helps, Jayne
