画像から動画へ(I2V)AIは、静止画にモーション、カメラワーク、物理演算を加えてアニメーション化します。写真やイラストをアップロードすると、Seedance 2.0、Kling 3.0、Luma AIなどのモデルがオリジナルの視覚スタイルを維持した4~20秒の動画クリップを生成します。
I2V技術の主要機能。
1枚の画像をアップロードすると、AIがシーンの動きを予測します。モデルが深度、オブジェクト、物理法則を解釈し、静止フレームから自然な動きを生成します。
パン、ズーム、オービット、ドリーなどのカメラの動きを指定できます。Luma AIとRunway Gen-4は映画的な結果のための精密なカメラパス制御を提供します。
I2Vはソース画像のキャラクターやオブジェクトの外観を維持します。Seedance 2.0のDirector Modeは顔固定を使用してショット間でアイデンティティの一貫性を保ちます。
高度なI2Vモードは複数の参照画像を受け付けます。Seedance Director Modeは、スタイル、キャラクター、シーン参照用に最大12ファイルをサポートします。
生成された動画は、写真、デジタルペインティング、アニメ、3Dレンダーなど、入力画像のアートスタイルを維持します。
初期クリップの長さを超えてI2V出力を延長できます。ほとんどのモデルが反復延長をサポートし、1枚の画像からより長いシーケンスを作成できます。
