全体の流れ(7ステップ)

キャラの原案を1枚作るMidjourney

白背景のソロポートレートで、主役の見た目とアートスタイルを確定させる「スタイルの正解」画像。

キャラクターシートに展開するGPT Image 2

原案を添付して「三面図・表情・ポーズ・小物」を1枚に詰めた設定資料に。動画生成でキャラの一貫性を保つための多視点参照画像になる。

ライブ会場の画を作るMidjourney / DALL-E 3

キャラを入れない「舞台だけ」の画。動画生成時に「キャラ=シート、舞台=この画」と役割分担させる。

曲を作るMiniMax Music 3(ローカル)

スタイル・Caption・セクションタグ付き歌詞の3点セットで指示。今回は約35秒のK-POP風ガールクラッシュ曲。

曲を解析して「秒数表」を作るWhisper + librosa(ローカル)

歌詞が何秒に乗っているか・BPM・サビ入りを解析。この秒数表が次のカット表プロンプトの土台になる。

H3 の「参照から動画」で映像を生成MiniMax H3(ローカル)

参照枠に「キャラシート+会場画+曲の音声そのもの」を入れ、秒単位のカット表プロンプトで指示。口パク・動きが曲に同期した映像が出てくる。

編集で連結して完成Premiere / ffmpeg

曲を1本敷いて、3クリップを秒数どおりに並べるだけ。クリップの境界は曲の変わり目に合わせて切ってあるので、並べればハマる。

今回の核心アイデア 3つ

🎧
① H3 に曲を「聴かせて」から映像を作る

H3 の参照枠(R2V)には画像だけでなく音声も入力できる。生成済みの曲を渡すと、口パクや体の動きが曲に同期した映像が生成される。「映像を作って後から曲を載せる」のではなく「曲を条件にして映像を作る」のがポイント。

🎬
② プロンプトは「秒単位のカット表」で書く

「SHOT 1 (0–2s | マイクの接写)…」のように、映画のカット割りをそのまま秒数付きで書く方式。ふわっと「MVを作って」ではなく、監督のコンテを渡すイメージ。スタイル指定と禁止事項(実写禁止など)を冒頭と末尾に二重に置くのがコツ。

📊
③ カット表の秒数は「曲の解析」から逆算する

Whisper(歌詞のタイムスタンプ)と librosa(BPM・ビート・盛り上がり検出)で曲を解析し、「サビ入りは16秒」「歌は26.2秒で終わる」を数値で把握してからカットを割る。勘ではなくデータでカット割りするので、編集で並べるだけでピタッと合う。

曲の解析結果(実例)

今回の35.5秒の曲を解析した結果がこちら。この「構造の地図」を見ながら3クリップに分割した。

秒数曲の中身映像クリップ
0〜4.6静かなイントロ(Yeah… / Wave check)クリップ1(15秒)
イントロ→Aメロ
4.6〜14.7Aメロ(Step in the light 〜 One mic, one move)
14.7〜16ビルド → 16秒ちょうどでサビ突入クリップ2(12秒)
ビルド→サビ
16〜26.2サビ 〜 Signal sent, no coming back(歌はここで終了)
26.2〜33.5インストの盛り上がり(エネルギー上昇)クリップ3(10秒)
熱狂→暗転
34〜35.5突然の無音 → ハードストップ
BPM 実測 94.0(ビート間隔 約0.64秒)。クリップの境界を「サビ前のビルド開始(14.7秒)」と「歌終わり(26.2秒)」に置いたことで、編集は並べるだけで完成する設計。

STEP 1: キャラ原案(Midjourney)
Solo portrait of a semi-realistic anime girl, jet-black high ponytail with electric-cyan inner color streaks, glowing star-shaped hairpin, wearing a sleek futuristic visor headset with a small glowing antenna. She has a calm confident expression, sharp detailed ice-blue eyes, wearing an oversized black techwear bomber jacket with white panels and cyan glowing trim lines, white crop top, black gloves, holding a wireless microphone with a glowing cyan grille. Bright pure white background, high-key lighting, soft cool cyan rim light, loose painterly brushstrokes, intricate detail, depth of field, digital painting, highly detailed face, concept art, no background characters, centered. --ar 4:5 --stylize 300
シグネチャーカラーを1色決めて(今回はエレクトリック・シアン)、以降のすべての画像・映像で「黒・白・シアンの3色縛り」を貫くと、MV全体に統一感が出る。
STEP 2: キャラクターシート(GPT Image 2)※原案画像を添付して使う
英語版(実際に使用)
Create a premium, modern high-fashion CHARACTER CONCEPT ART SHEET in a 16:9 widescreen layout on a near-black charcoal background.

THE ATTACHED REFERENCE IMAGE DEFINES THE ART STYLE AND THE CHARACTER — treat it as a strict style bible and reproduce its exact rendering technique and the exact same character in every figure on this sheet.

[STYLE — MIRROR THE REFERENCE EXACTLY]: Replicate the reference image's rendering verbatim: painterly semi-realistic anime digital painting, loose expressive brushstrokes, dramatic lighting, glowing electric-cyan neon accents, palette strictly limited to black, white, and electric cyan.

[STYLE PROHIBITIONS — ABSOLUTE]: no 3D render, no photorealism, no flat cel-shaded anime, no bold ink outlines, no chibi proportions, no style drift from the reference, no extra colors outside black/white/cyan.

[SUBJECT_DESCRIPTION]: The exact girl from the reference: jet-black high ponytail with electric-cyan inner color streaks, glowing cyan star-shaped hairpin, sleek visor headset with a thin boom microphone and a small glowing antenna, calm confident face with sharp ice-blue eyes. Outfit: oversized black techwear bomber jacket with white panels and glowing cyan trim lines, white crop top, black fingerless gloves, silver rings. Signature item: a wireless microphone with a glowing cyan grille. Her voice emits glowing electric-cyan sound-wave ribbons and geometric waveform shapes.

Layout Composition (Organize strictly into these sections):
1. LEFT PANEL: TURNAROUND & FACES
- MINI TURNAROUND: 3 small full-body vertical figures (neutral front, back view, side profile), identical outfit in all three.
- SILHOUETTE STUDY: 3 solid-white silhouettes matching the turnaround poses.
- EXPRESSION STUDY (Bottom Left): 4 close-up headshots (calm confident gaze, singing intensely with eyes closed, playful smirk, sharp performance glare).
2. CENTRAL PANEL: THE CENTERPIECE
- One giant, dominant full-body figure in a powerful mid-performance singing pose, mic raised close to her lips, cyan sound-wave ribbons swirling around her, maximum detail, perfect style-match to reference.
3. RIGHT PANEL: MULTI-POSE STUDIES
- POSE STUDY: 4 small-to-medium dynamic stances (unleashing a burst of cyan waveforms while singing, leaping mid-air with jacket billowing, crouching low holding the mic out to the camera, leaning back casually with hands in pockets), small handwritten-style labels.
4. BOTTOM RIGHT PANEL: DETAIL STUDY
- 5 small square crops: visor headset and face close-up, glowing star hairpin in hair, jacket's cyan trim and zipper hardware, fingerless glove with silver rings, the glowing microphone with a cyan sound-wave ribbon. Small handwritten-style labels.

No character name or logo typography anywhere on the sheet.
1枚のシートに三面図・表情・ポーズ・小物を全部詰めるのは、動画生成AIの参照枠が有限だから。「多視点の情報を1枚に圧縮」しておくと、参照1枠でキャラの一貫性が大きく上がる。
STEP 3: ライブ会場画(Midjourney / DALL-E 3 両対応)
Midjourney版
Stylized anime concept art of a massive luxurious concert arena at midnight, completely empty, no people, no crowd. A grand elevated center stage of black glass and polished chrome, a colossal curved LED screen glowing with electric-cyan waveforms, towering speaker monoliths, tiered VIP balconies with white marble and glowing cyan trim lines, crystal chandelier-like light rigs hanging from the darkness. Drifting stage fog, volumetric electric-cyan spotlights and lasers cutting through the dark. Palette strictly pitch black, stark white, and vivid electric cyan. Painterly semi-realistic digital painting, loose expressive brushstrokes, dramatic lighting, cinematic extreme wide establishing shot looking toward the stage, extreme depth. No characters, no photorealism, no 3D render. --ar 16:9 --stylize 300
DALL-E 3版(ChatGPTに貼る場合)
Create a 16:9 widescreen stylized anime concept art painting of a massive, luxurious concert arena at midnight. The arena is completely empty — absolutely no people, no crowd, no performers. Scene: a grand elevated center stage made of black glass and polished chrome, a colossal curved LED screen glowing with electric-cyan waveform patterns, towering speaker monoliths on both sides, tiered VIP balconies with white marble edges and glowing cyan trim lines, and crystal chandelier-like lighting rigs hanging from the darkness above. Atmosphere: drifting stage fog, volumetric electric-cyan spotlights and laser beams cutting through the dark. Palette: strictly limited to pitch black, stark white, and vivid electric cyan — no other colors. Style: painterly semi-realistic anime digital painting with loose expressive brushstrokes and dramatic lighting, like high-end concept art. Composition: cinematic extreme wide establishing shot from the audience floor looking up toward the stage, with extreme depth. Absolutely no characters, no photorealism, no 3D render look.
「NO CHARACTERS(キャラ禁止)」を強く念押しするのがコツ。人が写り込むと、動画生成時に参照の役割分担(キャラ=シート/舞台=この画)が崩れる。
STEP 4: 楽曲生成(MiniMax Music 3)― スタイル / Caption / 歌詞
スタイル
K-pop girl crush, dark electro-pop, powerful female vocal, heavy bass drop, 110 BPM
Caption(公式推奨の3部構成: Global Metadata → Vocal Details → Arrangement)
Global Metadata: K-pop girl-crush style dark electro-pop. Around 110 BPM, minor key. Mood: fierce, confident, sleek stadium energy. Punchy modern production with heavy synth bass, sharp claps, and bright electronic stabs.

Vocal Details: Solo female vocalist in her early twenties, powerful and charismatic. Sharp rhythmic chant-like delivery on the verse, soaring melodic hook with layered harmonies on the chorus, occasional whispered ad-libs. English lyrics, crisp articulation.

Arrangement: Intro is sparse — a dark synth-bass pulse, claps and whispered vocal chops, with one heavy kick hit as an accent. Verse rides a tight punchy groove with rolling hi-hats. Pre-chorus builds with a rising synth riser and accelerating drums, then ALL music cuts to complete silence for one spoken line, followed by a massive bass drop into the chorus. Chorus is the biggest section: heavy kick pattern, huge synth bass, chantable hook with layered harmonies. Outro strips back to the bare pulse, one final whispered line, then a hard clean stop.
歌詞(セクションタグ付き)
[Intro]
Yeah, turn the city lights low
Wave check, here we go

[Verse]
Step in the light with the neon glow
Black and cyan, run the whole show
Talk is cheap, I let the levels speak
One mic, one move, pushing past the peak

[Chorus]
Turn the silence up, let the wave run free
Every heartbeat locked to my frequency
Wave up, wave up, burning cyan bright

[Outro]
Signal sent, no coming back
max_duration は「上限」方式で、歌詞が尽きた時点で曲が終わる。歌詞量に対して少し多めの秒数を指定するのが安全(今回は歌詞10行に対して60を指定 → 35.5秒の曲になった)。BPM指定は110だったが実測は94 ― 指示どおりにならないこともあるので、テンポが重要なら生成後に実測するのがおすすめ。
STEP 6: H3 動画生成 ― クリップ1(15秒・イントロ→Aメロ)
ComfyUIのテンプレートは「MiniMax H3: 参照から動画」のAPIバッジが付いていない方を使う(APIバッジ付きは同名の有料クラウド版!)。image_1=キャラシート、image_2=会場画、audio=曲の該当区間(0〜14.7秒を切り出したもの)、継続時間=15秒。
Cinematic 2.5D animation, painterly semi-realistic anime style. Palette strictly limited to black, white, and electric cyan. NOT photorealistic, NO glossy 3D CGI, NO flat cel-shaded cartoon, no bold outlines.

WORLD: The venue is exactly the massive luxurious concert arena from <Picture 2>: black glass and chrome center stage, colossal curved LED screen glowing with electric-cyan waveforms, white marble VIP balconies, crystal chandelier light rigs, drifting stage fog, volumetric cyan spotlights.

CHARACTER: The young woman from <Picture 1>, exactly as designed: jet-black high ponytail with electric-cyan inner color streaks, glowing cyan star-shaped hairpin, sleek visor headset with a thin boom microphone, oversized black techwear bomber jacket with white panels and glowing cyan trim lines, white crop top, black fingerless gloves, holding a wireless microphone with a glowing cyan grille. Sharp ice-blue eyes, painterly matte skin. Her singing mouth movements are precisely synchronized with <Audio 1>.

INTRO & VERSE SHOT DESIGN (5 Filmic Cuts):
• SHOT 1 (0–2s | Macro Detail): Extreme macro close-up of the glowing cyan mic grille in darkness. On the whispered "Yeah", one soft cyan sound ripple pulses from the grille.
• SHOT 2 (2–4.6s | Reveal): Medium shot. She raises her head into a single spotlight on the grand stage, singing softly. On the words "Wave check", bold flat-graphic typography "WAVE CHECK" flashes beside her in electric cyan.
• SHOT 3 (4.6–9.5s | Verse Groove): Slow tracking shot as she walks up the glowing stage stairs singing; as she sings "Black and cyan", the cyan trim lines of her jacket ignite one by one in rhythm, the giant LED screen pulsing waveforms behind her.
• SHOT 4 (9.5–12.3s | Attitude): Close-up on her face. She sings "Talk is cheap" with a confident smirk directly into the camera, thin cyan waveform ribbons drifting around her.
• SHOT 5 (12.3–15s | Typography Stamp): Medium shot, giant flat-graphic audio level bars rising on the LED screen behind her as she sings "I let the levels speak". Then bold typography "ONE MIC." and "ONE MOVE." stamps across the frame in sync with the two vocal hits. Hold final frame.

Weighty natural animation, oversized jacket reacting fluidly to her movement, 24fps filmic motion, shallow depth of field. NOT photorealistic, no 3D render, no cel shading, no bold outlines.
STEP 6: H3 動画生成 ― クリップ2(12秒・ビルド→サビ)
audio=曲の14.7〜26.2秒を切り出したもの、継続時間=12秒。
Cinematic 2.5D animation, painterly semi-realistic anime style. Palette strictly limited to black, white, and electric cyan. NOT photorealistic, NO glossy 3D CGI, NO flat cel-shaded cartoon, no bold outlines.

WORLD: The venue is exactly the massive luxurious concert arena from <Picture 2>: black glass and chrome center stage, colossal curved LED screen glowing with electric-cyan waveforms, white marble VIP balconies, crystal chandelier light rigs, drifting stage fog, volumetric cyan spotlights and lasers.

Sharp ice-blue eyes, painterly matte skin. Her singing mouth movements are precisely synchronized with <Audio 1>.

CHORUS SHOT DESIGN (4 Cuts with Typography):
• SHOT 1 (0–1.5s | Launch): Low-angle shot. She strides toward the center of the grand stage as the music surges upward, rows of cyan stage lights and the chandelier rigs igniting one after another.
• SHOT 2 (1.5–7s | Chorus Power): Dynamic orbiting camera around her as she sings the chorus at full power, concentric cyan shockwave rings expanding from her with each beat, stage fog blown outward across the marble balconies.
• SHOT 3 (7–9s | Wave Up): Two rhythmic jump-cut punch-ins as she sings "Wave up, wave up" — bold flat-graphic typography "WAVE UP" stamps on screen twice, once per vocal hit, then a burst of bright cyan light floods the frame from the LED screen on "burning cyan bright".
• SHOT 4 (9–12s | Signal Sent): She lowers the mic, turns, and walks slowly away from the camera into the darkness of the stage while singing "Signal sent, no coming back"; typography "SIGNAL SENT." fades in beside her silhouette. Hold final frame.

Weighty natural animation, oversized jacket reacting to the shockwaves, 24fps filmic motion. NOT photorealistic, no 3D render, no cel shading, no bold outlines.
STEP 6: H3 動画生成 ― クリップ3(10秒・インスト熱狂→暗転)
audio=曲の26.2〜35.5秒(歌なしのインスト区間)、継続時間=10秒。歌がない区間なので「リップシンクせず、リズムに合わせて動く」指定に切り替えているのがポイント。
Cinematic 2.5D animation, painterly semi-realistic anime style. Palette strictly limited to black, white, and electric cyan. NOT photorealistic, NO glossy 3D CGI, NO flat cel-shaded cartoon, no bold outlines.

WORLD: The venue is exactly the massive luxurious concert arena from <Picture 2>: black glass and chrome center stage, colossal curved LED screen, white marble VIP balconies, crystal chandelier light rigs, stage fog swirling, strobing electric-cyan lasers.

CHARACTER: The young woman from <Picture 1>, exactly as designed: jet-black high ponytail with electric-cyan inner color streaks, glowing cyan star-shaped hairpin, sleek visor headset with a thin boom microphone, oversized black techwear bomber jacket with white panels and glowing cyan trim lines, white crop top, black fingerless gloves, holding a wireless microphone with a glowing cyan grille. Sharp ice-blue eyes, painterly matte skin. She does not sing in this clip — this is a pure instrumental performance climax, her movements locked to the rhythm of <Audio 1>.

INSTRUMENTAL FINALE SHOT DESIGN (4 Cuts, No Lip Sync):
• SHOT 1 (0–3s | Ignition): Wide shot of the grand stage. She spins the mic in her hand and starts moving to the beat, cyan lasers and the LED screen strobing faster and faster with the rising synths.
• SHOT 2 (3–6.5s | Frenzy): Speed-ramp orbiting camera accelerating around her dancing silhouette, cyan waveform ribbons spiraling tighter and tighter, frames flickering between normal and black/cyan inverted colors on the beat.
• SHOT 3 (6.5–7.8s | Peak): Everything peaks at once — she raises the glowing mic high overhead and a massive cyan shockwave dome erupts across the entire arena, the chandeliers and LED screen flaring white-cyan.
• SHOT 4 (7.8–10s | Blackout): On the sudden dead silence, every light and the giant LED screen shut off instantly. A single cyan rim light traces her silhouette in the darkness, she flashes a confident parting smirk, then the frame snaps to pure black. Hold black frame.

Weighty natural animation, 24fps filmic motion. NOT photorealistic, no 3D render, no cel shading, no bold outlines.

INTRO & VERSE SHOT DESIGN (5 Cuts, Light-Driven):
• SHOT 1 (0–2s | Darkness): Wide shot of the pitch-dark arena. On the whispered vocal, a single faint cyan ripple crosses the giant LED screen, revealing her silhouette at center stage.
• SHOT 2 (2–4.6s | First Light): The crystal chandeliers flicker alive one by one above her as she starts singing, cold cyan light raining down through the stage fog.
• SHOT 3 (4.6–9.5s | Beat Sync): Medium shot; every beat of the music fires a pulse of light through the floor's cyan trim lines under her feet as she sings and steps forward in rhythm.
• SHOT 4 (9.5–12.3s | Waveform Halo): Close-up; glowing cyan waveform ribbons rise from the mic and orbit her head like a halo while she sings with a sly smirk.
• SHOT 5 (12.3–15s | Level Surge): Wide shot; the LED screen behind her erupts into towering equalizer-like light columns surging upward with her voice, spotlights flaring. Hold final frame.

生成時間の実測(RTX 3090)

生成設定所要時間
曲(Music 3)35.5秒の曲数分
動画 初回480p / 15秒 / 参照画像2枚+音声約24.5分(モデルロード込み)
動画 2回目以降480p / 10〜15秒約12〜17分
H3は「秒数が2乗で効く」モデルなので、短いカットに割って生成するのが時間的にも有利。まず480pでテストして、気に入ったカットだけ高解像度(768p)で作り直すのが効率的。

ハマりやすい注意点

⚠️
同名の「APIバッジ付き」テンプレートは有料クラウド版

テンプレート検索で「MiniMax H3: 参照から動画」が2つ出てくる。タグに「API」と付いている方は1回ごとにクレジット課金されるクラウド版。ローカル無料で作るなら、APIタグのない方を選ぶこと。ノードに「credits/Run」表示が出ていたら要注意。

🎤
リップシンクのカットは短めに割る

H3の口パク同期はクリップが長いと末尾でズレる報告がある。歌唱カットは9〜15秒程度に割り、歌のない区間は「リップシンクなし・リズム同期」の指定に切り替える。

💾
アラインメント解析は「実際に使った歌詞」で

曲の解析(歌詞タイムスタンプ取得)は、生成に使った歌詞と1文字でも違うテキストで回すと結果が大きく狂う。歌詞の版管理に注意。
