Should I get Final Cut Pro 4 or Final Cut 4.5 HD? What is the big difference? I am using it for video editing but I'm not making feature films. I'm making 10-20 minute movies....some are home videos-others are 5-6 minute promotional videos for my organization. Is there really a need for HD? What are the advantages? I will be burning my creations to a LaCie dvd burner. How much different is express from the full version? I have a friend that gave me Final Cut 4 pro, but I know thereare newer versions out so that's why I want to know if I should just buy another version?
