There is no formula for a sure-fire creative sample. It can be narrative, documentary, or experimental. It can be a music video for a band, a clip tape set to music, a dance, or lip-synched scene. We’ve seen everything from a documentary on colony collapse disorder to an ad for jeans. It can be an anti-war video or two guys on a trampoline. Personal confessions and homages to great directors have caught our interest, as have well-choreographed fight scenes. It can use a 35mm camera, a camcorder, a cell phone, still photos, a typewriter, or a videogame’s 3-D graphics rendering engine. Anything goes.
