Finally, I have found the time to put a video together for Alien Apocalypse. I have wanted to do this for ages.
Personally, I like book trailers. It is a good way to get across your story in an easy to digest clip. It also has the added benefit of evoking an atmosphere that a written blurb cannot achieve.
It is amazing what you can do with free software, a few royalty free images, audio, and old-fashioned elbow grease!
