Frenchman,
If you mean how do you make a whole continuous video after you have split and removed sections of the video.
It is not done on the timeline.
When you have completed all of your edits, you click on the Produce Module, and produce the project to the final video. You have several choices of the type of file you can create depending on your use of the final output.
Or if you want to make a DVD, you click on the Create Disk Module.
