テキストから動画(T2V)AIは、ディープラーニングを使用してテキスト記述を動画クリップに変換します。シーンを記述するプロンプトを入力すると、Seedance 2.0、Sora 2、Kling 3.0などのモデルがモーション、照明、カメラワークを含む動画を数秒で生成します。
T2Vが他のAI動画手法と異なる点。
シーンを自然言語で記述します。T2Vモデルがテキストから被写体、アクション、スタイル、カメラアングル、ムードを解析して動画を生成します。
最新のT2Vモデルは30~120秒でクリップを生成します。Luma AIは約120秒で120フレームを生成し、Seedanceは90秒以内に4Kクリップを生成します。
T2Vはフォトリアル、シネマティック、アニメ、水彩画、抽象画など多様な視覚スタイルをサポートします。プロンプトキーワードまたはモデルパラメーターでスタイルを制御します。
クリップは1回の生成で4秒(Seedance)から20秒(Sora)、最大4K解像度です。Klingのマルチショットツールは2分超のシーケンスをサポートします。
構造化されたプロンプトはより良い結果を生み出します。SCELAフレームワーク(Subject、Camera、Environment、Lighting、Action)は出力品質を最大40%向上させます。
T2VはクラウドGPU上で動作します。すべての主要ツールはウェブブラウザで動作し、ローカルGPU、ダウンロード、技術的なセットアップは不要です。
