Motion
Purpose, and one hero
Every move has a job, and each beat has one hero motion.
Takeaways
- Ask what each move tells the viewer.
- One hero per shot; the rest support it.
- Quiet things stay quiet, so the hero reads.
What it means
Motion that does not direct the eye, show cause and effect or carry a thought is noise. In each shot one thing is the hero, a second supports it a few frames behind, and everything else stays quiet.
In a RasanAI film
Every tween is scored with a layer (hero, support or ambient). The hero travels the furthest and fastest; support moves less and arrives later. Decorative loops on content are rejected.
