Know Your Time Constraints.

Often your demo reel will be given to you as an assignment in a class devoted to completing the project in time for graduation; many schools impose time constraints within a certain range. I remember that my demo reel had to be at least a minute and a half long, but no more than two minutes; this is an average range, though some schools will go as high as three minutes. Later, you may be piecing together a new demo reel to meet submission guidelines for a specific employer or call-out, but no matter the reason, you should always check the minimum and maximum lengths of time allowed. This will help you plan your content, and how you will space it.
