実際に機能する12のAIラップ動画プロンプト

優れたラップビデオのプロンプトは、ムードボードではなくショットの説明です。演者、場所、光、そしてカメラの動きを1つ挙げたら、そこで終わりです。以下の12個のプロンプトはその構造に従っています。これらはこのスタジオを通じてSeedance 2.0向けに書かれており、プロンプトに別段の指定がない限り、ポートレートをアップロードすることを前提としています。

これらは出発点として使ってください。場所、光の色、アクションを変えても構いませんが、アイデンティティとガードレールの文はそのまま残してください。クリップの途中でモデルが新しい人物を勝手に作り出してしまうのを防ぐのは、まさにこれらの文なのです。

すべてのプロンプトに必要な構造

1. 被写体。 ショットに誰が写っているか、そして何人いるか。
2. 場所。 表面と背景を伴う具体的なロケーション。
3. 光。 方向、色、硬さ。
4. カメラ。 動きを1つ、高さを1つ、距離を1つ。
5. ガードレール。 顔と衣装を保つ、テキストなし、ウォーターマークなし、余計な人物なし。

プロンプトにこの5つのうち1つでも欠けていると、モデルはその隙間をありきたりな選択で埋めてしまいます。ドリフトが生じるのはそこからです。

1. クラブステージのツーショット

Use the two people in the uploaded photos as the only performers. A small club stage at night, purple and magenta lights cutting through haze, a packed crowd in silhouette at the front. The two rappers stand side by side trading verses, one gesturing to the crowd while the other nods to the beat. One continuous handheld shot at chest height that pushes in from the back of the stage to a tight two-shot. Keep the faces, hair, outfits and body proportions exactly. No extra people, no text, no watermark.

2. ソロブースのクローズアップ

Use the person in the uploaded photo as the only performer. A narrow recording booth at night, a condenser microphone on a shock mount, warm tungsten key light from the left and a cold blue rim light behind. The rapper leans into the mic and performs to camera. One slow dolly-in from medium shot to close-up, shallow depth of field. Keep the face, hair and outfit exactly. No headphones swapping, no text, no watermark.

3. 屋上サイファー

Use the person in the uploaded photo as the lead performer. An empty rooftop car park at night, wet concrete reflecting orange sodium lights, a circle of silhouetted figures clapping. The rapper walks into the centre and performs, turning slowly to face the camera. One low-angle tracking shot circling at knee height, ending on a medium close-up. Keep the face, hair and outfit exactly. No fighting, no extra foreground people, no text, no watermark.

4. レトロな歩道のデュオ

Use the two people in the uploaded photos as the only performers. A sunlit city sidewalk in the mid-1990s, a large silver boombox between them, brick wall and parked cars behind. The pair trade verses and laugh between lines, baggy outfits moving with the beat. One continuous handheld shot with a slight zoom, warm film grain and soft VHS halation. Keep the faces, hair and outfits exactly. No period-inaccurate screens, no text, no watermark.

5. ドリルの屋上、冷たくワイドに

Use the person in the uploaded photo as the only performer. A wide empty rooftop at blue hour, cold overcast light, distant tower blocks out of focus. The performer stands still with a hood up, then turns to camera and steps forward once. A slow low-angle push-in from a wide shot to a medium shot. Keep the face and outfit exactly. No weapons, no crowd, no text, no watermark.

6. ゴールデンエラの地下室

Use the person in the uploaded photo as the only performer. A low basement with exposed brick, a single warm tungsten bulb overhead, a turntable and stacked records behind. The rapper performs to camera with one hand marking the beat. A locked-off medium shot with a very slow zoom. Warm film grain, soft contrast. Keep the face and outfit exactly. No readable labels, no text, no watermark.

7. トンネルのウォーク

Use the person in the uploaded photo as the only performer. A concrete pedestrian tunnel at night, repeating overhead lights, wet floor reflecting the performer. The rapper walks toward the camera while performing, hands moving with the beat. One steady backward-tracking shot at chest height. Keep the face, hair and outfit exactly. No extra people, no graffiti text, no watermark.

8. ステージのシルエット・リビール

Use the person in the uploaded photo as the only performer. A dark stage with a single white spotlight from behind, haze in the air. The performer starts as a silhouette and steps forward into the light, revealing the face. One slow push-in from wide to medium. Keep the face and outfit exactly. No band, no crowd, no text, no watermark.

9. クラウドサーフのエネルギー、群衆の顔はなし

Use the person in the uploaded photo as the only performer. A packed club seen from the stage, hands raised in silhouette below, magenta and blue lights sweeping across haze. The rapper leans over the front edge and performs to the crowd, then looks down the lens. One handheld shot at chest height with a slight push-in. Keep the face and outfit exactly. No individual crowd faces, no text, no watermark.

10. 夜のドライブの背景

Use the person in the uploaded photo as the only performer. The back seat of a moving car at night, city lights streaking past the window, cool blue interior light on the face. The rapper performs to camera, one hand on the seat. One locked-off shot with slight handheld float. Keep the face and outfit exactly. No visible driver, no dashboard text, no watermark.

11. リリックビデオ用のビジュアルベッド

Use the person in the uploaded photo as the only performer. A dim room with a single practical lamp, deep shadows, the performer framed slightly to the right with empty wall on the left. The rapper performs quietly to camera, minimal movement. A locked-off medium shot with a slow drift. Keep the face and outfit exactly. No text, no watermark.

12. レーベルのショーケース

Use the two people in the uploaded photos as the only performers. A bright photo studio with a seamless grey backdrop, soft even light. The pair stand relaxed, one gesturing toward the other, then both look to camera. One slow dolly-in from medium to medium close. Keep the faces and outfits exactly. No logos, no text, no watermark.

プロンプトを壊さずに調整する方法

一度に1つのブロックだけを変えてください。場所を入れ替えるなら、光とカメラの文はまったく同じにしておきましょう。そうすれば場所の変更が効果的だったかどうかを判断できます。カメラを変えるなら、場所と光は固定したままにします。

5秒のクリップに2つ目のカメラの動きを加えないでください。同じレンダーに群衆と車と衣装チェンジを加えないでください。余分な要素はそれぞれ、ドリフトしうるもう1つの対象であり、モデルは人間のクルーのようには優先順位をつけてくれません。

ガードレールの文は省略できません

最後の2つの文 — 顔と衣装を保つ、テキストなし、ウォーターマークなし、余計な人物なし — が、一貫性の作業の大部分を担っています。地味な文ですが、クリップが使えるものになる理由はそこにあります。プロンプトをゼロから書き直す場合は、これらの文をそのままコピーしてください。
