Prompt tips for Runway
Start with a still image as a reference frame and use Gen-3 to animate it — results are more controlled than pure text-to-video
Describe camera movement explicitly: 'slow dolly forward', 'handheld tracking shot', 'aerial crane descent' for cinematic feel
Keep subject descriptions concrete and specific — 'a woman in a red coat walks through a Tokyo crosswalk at night, rain' outperforms abstract prompts
Use short clip prompts (4–8 seconds) and chain them rather than attempting long single generations which degrade in quality
