  • Use a strict block order: CAMERA -> SUBJECT -> ACTION -> ENVIRONMENT -> LIGHTING -> STYLE.
  • 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.

What each block does

BlockPurpose
referencesOptional image inputs: product, character face, or style frame. Use these where the model supports references; otherwise treat them as setup notes.
brandBrand constraints: colors, logo handling and voice. Models approximate hex colors and cannot render exact logos reliably; use a reference image or add exact logos in post.
sceneWhere it happens: location, time of day, weather, mood of the space.
subjectWho or what the shot is about. Keep it to one clear subject — models blur focus when given several.
actionWhat visibly happens during the clip. Describe motion the camera can see, not internal states.
cameraShot framing and movement. One movement per clip reads best on every current model.
lightingLight source, quality and shadow behavior. The single highest-leverage block for realism.
styleAesthetic direction: film stock, color palette, references, tone.
audioDialogue, ambient sound and music. Only Veo 3.1, Kling 3.0 and Seedance 2.0 render audio natively.
technicalRender settings: aspect ratio, duration, fps, seed for reproducibility, negative prompt.
