I have an upcoming final cut project. The client wants a 3-4 minute, fast-paced video with lots of shots. I have viewed several motion template sites, but most of the templates I like are 30-60 seconds. What is the best practice to create a longer video? Also, I'm concerned about viewer fatigue after watching fast-transitions for 3 minutes. What's the best way to approach this? I want the wow-factor, but I don't want to drain the audience in the process.
