製品形状とブランド要素を保ちながら、製品の動き、環境反応、カメラ経路、最後のヒーローフレームを設計します。

PROMPT
Create a premium product-film sequence in which the product remains geometrically exact and visually dominant. Use a small number of connected shots; each shot must communicate one feature and one camera idea.

PRODUCT BIBLE
{{subject}}
Preserve silhouette, dimensions, component placement, material boundaries, finish, packaging, controls, ports, and supplied branding. Never invent text, logos, buttons, seams, or functions.

PRODUCT BEHAVIOR
{{product_behavior}}
Describe visible, physically possible movement or transformation: rotation, assembly, opening, liquid flow, light response, control feedback, or human interaction. State the starting state, action, and stable end state.

SET AND SCALE
{{scene}}
Define surface, background, practical elements, scale references, product position, and spatial layout. Keep the environment visually supportive and uncluttered.

ENVIRONMENTAL RESPONSE
{{environment_motion}}
Describe restrained particles, condensation, vapor, fabric, liquid, reflections, shadows, or light sweeps and how they react to the product’s movement.

CAMERA
{{camera_motion}}
Plan the establishing hero view, feature-revealing move, macro detail, and final settling movement. Give every shot its framing, angle, lens character, focus transition, start frame, and end frame. Generate shots separately when the chosen model does not reliably support multi-shot prompts.

ART DIRECTION
{{style}}
Specify palette, material response, key and rim lighting, contrast, atmosphere, motion energy, and commercial genre. Keep reflections controlled and contact shadows grounded.

FINAL HERO FRAME
{{end_frame}}
End on a stable, uncluttered product pose with intentional negative space for later typography; generate no text in the video.

DELIVERY CONSTRAINTS
{{constraints}}
Maintain product geometry, branding, handedness, scale, color, and lighting continuity. No melting surfaces, invented features, floating contact points, warped labels, flicker, duplicate products, abrupt camera jumps, or accidental crops.

Negative prompt

identity drift, face mutation, age change, wardrobe change, warped anatomy, rubbery limbs, sliding feet, floating contact, object morphing, duplicate subjects, disappearing props, geometry drift, flicker, exposure pumping, texture crawl, background warping, teleportation, abrupt zoom, unmotivated cut, camera jitter, reversed screen direction, text, subtitles, logo, watermark

制作手順

  1. 被写体とシーンを先に定義し、次にカメラ、照明、スタイルを入力します。
  2. 最初の結果では人物同一性、形状、構図、主動作を確認します。
  3. 反復ごとに動作またはカメラ指示を一つだけ変更します。

動画プロンプトの原則

  • 動画の長さは生成設定で選び、プロンプト変数には入力しません。
  • 人物がいる場合は外見、表情、視線、姿勢、重心移動、手の動き、終了状態を記述します。
  • 人物がいない場合は前景・中景・背景の動きとカメラ経路を中心にします。
  • Image-to-Videoでは画像が外見を決めるため、テキストは動きを優先します。
  • 1クリップにつき主動作一つ、動機のあるカメラ移動一つから始めます。

検証

顔、手、製品形状、接地、画面方向、光、背景位置、ちらつき、フレーム間変形を確認します。
