Among all the things floating around in my head, cutting a trailer is at the top of the list. I've been experimenting with a shorter timeline recently to get used to it. (Don't judge me for using iMovie, mk?)
Everything I've researched and studied leads me to believe that a 30, 60, or 90 second trailer for the film will be ideal. I don't think we need to have much more than that online.
So, then, the question remains: how do you sell a 60-minute documentary in 90 seconds or less?
