Native audio: describe dialogue, ambient sound and music directly in the audio field.

Keep the camera block to a shot type plus one movement; stacking moves degrades output.

Runway recommends clear, direct language; text-to-video should describe both visual elements and motion.
Image-to-video prompts should focus on describing the motion of the scene.
