Retention Mechanics
Visual Tension Line
Definition
A visual tension line is compositional energy, diagonal lines, gaze direction, or motion, that pulls the eye through the frame.
Full explanation
Visual tension lines guide attention to the subject, text, or payoff. Editors use framing, crop, and motion to create tension that makes static moments feel alive.
Why it matters
Retention is visual as much as narrative; the eye must always have somewhere to go.
