Natural image-to-video motion

Direct character performance, environmental response, and camera path instead of typing a duration. For scenes without people, focus on spatial motion and camera direction.

PROMPT
Selector policy: Treat selected presets as operating requirements for strategy, format, and validation—not decorative labels. If a preset conflicts with supplied evidence, preserve the evidence and state the conflict and adjustment. Never invent unique facts absent from the preset or source.

Use the supplied first-frame image as the visual source of truth. Do not redescribe or redesign what is already visible. Create one continuous, physically coherent shot.

MOVING SUBJECT OR FOCAL ELEMENT
{{moving_subject}}
If a person is present, preserve the same face, apparent age, body proportions, hairstyle, clothing, accessories, initial pose, and screen position. If there is no person, explicitly treat the named object, landscape feature, weather system, or light source as the focal element.

SUBJECT PERFORMANCE
{{subject_action}}
Describe one primary action with a readable beginning, transition, and resting state. For a person, include gaze, facial expression, breathing, weight shift, hand behavior, and interaction with the environment. For a person-free background shot, describe only the focal element’s natural change and omit human performance.

ENVIRONMENTAL MOTION
{{environment_motion}}
Describe how hair, fabric, foliage, dust, water, smoke, reflections, shadows, practical lights, and background traffic react consistently to the subject and wind. Use restrained secondary motion; nothing moves without a cause.

CAMERA
{{camera_motion}}
Define framing, angle, camera support, one motivated move, subject relationship, focus behavior, and the point where the camera settles. Avoid combining contradictory moves.

DEFAULT LOOK AND CONTINUITY
Preserve the input image’s medium, lighting, palette, lens character, identity, anatomy, object geometry, screen direction, scale, and background layout. Use natural acceleration and restrained secondary motion. No morphing, flicker, teleportation, duplicate elements, sliding feet, rubbery limbs, sudden zooms, text, logos, or unmotivated cuts.

Production workflow

  1. Define the subject and scene first, then camera, lighting, and style.
  2. In the first result, judge only identity, geometry, composition, and the primary action.
  3. Change one action or one camera instruction per iteration.

Video prompting principles

  • Choose duration in the product’s generation settings; do not type it as a prompt variable.
  • For people, describe appearance, expression, gaze, posture, weight shift, hand behavior, and the action’s resting state.
  • Without people, prioritize foreground/midground/background motion and the camera path.
  • In image-to-video, the image establishes appearance, so use text primarily for motion.
  • Begin with one primary action and one motivated camera move per clip.

Verification

Inspect face, hands, product geometry, ground contact, screen direction, lighting direction, background position, flicker, and frame-to-frame deformation.
