Can I have captions

Yes definitely. You can have as many as you want. I would warn against having too many as it will distract from the video aspect of the movie. For the first page I would ask that you think of a title and sub title plus any other captions. Eg the title of a movie could be “Mickey’s 21st Birthday” and the sub title “5th September 2011″. A further caption could be “The day a boy became a man”. You just need to be aware that if you have too much on screen at one time it may look too busy.
