There are two primary things you can do to speed up rendering.
1. Get a faster CPU
2. Turn on hardware acceleration. (Or if already turned on, get a faster GPU.)
There are some secondary actions you can also do.
1. Add more memory.
2. Get more/faster hard drives.
And finally a third method which may have some limited application.
1. Avoid QuickTime.
Thanks for the reply. I did update my memory. I maxed it out a while ago. I also have a 1terabyte hard drive. Ultimately I will invest in a new computer but I'm trying to leg along. What file format would you suggest for videos? Should it be mp4 instead? I do have a .MOV file format and all it is is basically a background of sky footage I have.
