If you are new to video editing it would be worth your time to watch some of the video courses available to you on Lynda.com.
Linked below are Lynda.com courses for iMovie and Adobe Premier Elements. Both of these Lynda.com courses run about 3 hours. Though that may seem like a lot of time. Learning some of the basics of these programs early on can save you some headaches and time as your work on your video editing project.
