Why Gen-4 Turbo won December 2025:
- Generates clean motion in 3–5 seconds

- Perfect balance of speed + quality for mobile creators
Perfect Use Cases:
✔ Aesthetic b-rolls

Older models (Gen-1 / Gen-2) struggled with motion blur, camera realism, and neon lighting. Running scenes usually looked flat and less cinematic.
Runway Gen-4 Turbo — cinematic motion blur sample.
Gen-4 Turbo produces sharper silhouettes, smoother streaked motion, and realistic neon reflections — giving a true “cinematic runner shot” effect.
