プロンプトの書き方: 正確なセリフを、キャラクター名のラベルを付けて引用符の中に書きます。必要に応じて、話し方のトーンも指定します。

Dimly lit basement on a rainy city night: flickering fluorescents cast harsh shadows over folding chairs, glowing laptops with editing software, hooded young filmmakers with vintage cameras and energy drinks huddled in industrial space—concrete walls, exposed pipes, rain-streaked windows. Smoke drifts from ashtray amid crackling creative energy. Camera starts wide on gritty basement, pushes slowly to medium on central Tyler, holds on his intense face as he leans forward gravelly: "The first rule of AI filmmaking: You DO talk about AI filmmaking." 
Pulls back to group's smirking nods. Background: rain hum, traffic, buzzing lights, laptop fans, distant thunder. Style: desaturated, high contrast, film grain, teal-amber grade, shallow DOF on Tyler.

Slow dolly-in, black-and-white vintage film look with soft focus and film grain. A young woman in a flowing Edwardian dress plays a grand piano in a lavish 1900s drawing room. Camera moves from her gliding fingers to a close-up of her emotive face lit by flickering candelabra. Velvet drapes, gilded furniture, and chandeliers drift into view with ornate shadows and a soft breeze moving sheer curtains. Melancholic Chopin-style nocturne plays on solo piano, recorded like an antique phonograph warm mono tone, with faint crackle, floor creaks, and distant ticking clock

A weathered fisherman in a yellow raincoat stands on a jagged cliff at storm's edge, his face etched with quiet resolve as waves crash below. Salt spray clings to his beard, eyes fixed on a distant horizon where thunder rumbles. The camera holds a low-angle medium shot, rain blurring the lens slightly, building a mood of defiant hope amid chaos—raw, windswept, and profoundly human. No audio, No dailogues

A majestic red dragon bursts from a volcanic crater at dawn, scales glinting in fiery orange light as it unfurls massive wings and launches skyward with a thunderous roar echoing off jagged black rocks; begin with a low static shot framing the steaming lava pool, then smoothly track upward alongside the dragon's powerful ascent to follow its wingbeats, pan wide left to reveal the vast snow-capped mountain range below, and end with a dramatic pull-back zoom out to silhouette the beast against the rising sun, with howling wind and trailing embers filling the air

Neon-lit Tokyo ramen shop at midnight: steam rises from simmering broth pots behind counter where chef works with rapid precision. Red lanterns glow warmly over weathered wooden bar; three customers slurp noodles appreciatively. Outside small window, rain streams down narrow alley with passing umbrellas; subway rumbles subtly vibrate floor. Chef tosses noodles into boiling water—splash and sizzle amid clanking ladles, rhythmic knife chops on scallions, customer murmurs, rain patter, muffled J-pop from vintage radio, distant sirens. Camera: medium wide shot of intimate space, pushing occasionally to close-ups on steaming bowls and chef's hands. Atmospheric, authentic mood capturing late-night Tokyo soul.

A boy and girl in casual dress walk hand-in-hand through a bustling Tokyo night market, cherry blossoms drifting in the breeze and neon signs flickering overhead; they laugh softly as distant street chatter and upbeat J-pop hum in the background; medium angle shot tracking alongside them, anime style like vibrant color palette of deep indigos, glowing pinks, and warm ambers, soft cel-shaded lines, ethereal glow on their faces, subtle sakura petals swirling in slow motion

Hospital waiting room pre-dawn: harsh fluorescents buzz, casting cold blue-white glow on vinyl chairs, scuffed linoleum. Middle-aged man sits alone, elbows on knees, face buried in hands. Wall clock ticks loudly; window frames parking lot lights pooling in darkness—time suspended. Audio: oppressive fluorescent hum/flicker, echoing ticks, distant footsteps/corridor echoes, muffled intercoms, man's heavy breathing/jacket rustle, corner vending hum. No music—raw waiting starkness. Mood: desaturated clinical blues/greens, harsh overhead shadows under eyes; compose man small/isolated amid empty chairs, anxious/lonely, molasses-slow time.

プロンプトの簡単なフレームワーク

すべてのプロンプトを、次の要素で構成します。

  1. 設定と照明 & - いつ、どこで、どんな光の条件か

  2. 被写体と動作 & - 何が起きていて、誰が関わっているか

  3. カメラの指示 - ショットがどう動き、どうフレーミングされるか

  4. 音声要素 - セリフ、環境音、音楽

  5. ムードとスタイル & - 全体のトーンとビジュアルの美学

フレームワークを使った例:

[Setting] Abandoned subway station at midnight, emergency lights casting red glow through dust and fog

[Subject] A street artist spray paints a massive mural on the curved tunnel wall, moving with practiced rhythm

[Camera] Start wide revealing the vast underground space, slowly push in while circling the artist, ending tight on their intense focused expression

[Audio] Spray paint hissing and echoing, dripping paint splatters, distant train rumbling through tunnels, artist's breathing steady and meditative, occasional footsteps echoing in the distance

[Mood] Gritty urban documentary feel with high contrast, atmospheric haze, rebellious energy meets artistic meditation

プロのヒント:

✓ 具体的に書く - 「good lighting」より「Warm golden hour lighting」のほうが効果的です
✓ 音声を重ねる - 必要に応じて、セリフ、環境音、音楽を組み合わせます
✓ ネガティブプロンプトを使う - 望まないものを明示的に指定します
✓ 音声を映像に合わせる - 画面に映っているものにふさわしい音になっているか確認します
✓ ペースを試す - ショットの長さやカメラの速度を変えて試します

まずはシンプルに始め、各要素に慣れたら少しずつ複雑さを加えていきましょう。
