Good Grief. If your goal is to shoot a scripted movie with a camcorder, by all means. BUT the vast majority of people want to capture unscripted live action. That is kids playing in pool on vacation. Grandma riding a roller coaster for the first time. Bobby's 5th birthday and seeing his face when he unwraps the Star Wars light saber toy he wanted.
That is real life, unscripted. That is what most people want. What is MORE useful is compiling all this content into a form will not bore your audience to tears. That is EDITING.
