このラップ動画、 人物だけ別人に入れ替えてみた。 元動画はKling 4.0。 激しい手振りとカメラワークの中でも、 リップシンクがかなり自然。 そこからPollo Recastで、 動き・音声・カメラワーク・構成はそのままに、 人物だけまったく別のキャラクターへ変更。 しかも、 「元動画の良さを残したまま別バージョンを作れる」 というのがかなり面白い。 撮り直しも、モーション再構築も不要。 完成した動画をベースに、 キャラクターや世界観を差し替えてもう一度使える。 こういう“動画の再利用”が普通になってくると、 AI動画の作り方そのものが変わりそう。 みんなは元キャラとRecast後、 どっちが好き？👀 リプ欄にクーポンコード置いておきます⚠️ ✅Kling 4.0プロンプト: Create a 30-second ultra-photorealistic live-action music video of a stylish young adult female rapper performing directly toward the camera. Use the exact same woman as the provided reference image. Preserve her facial identity, hairstyle, makeup, body proportions, clothing, jewelry, and overall appearance consistently throughout the entire video. SETTING: A dark minimalist music studio with a matte black and charcoal-gray background. Subtle neon tube lights glow in the background: deep violet / magenta on one side cool electric blue on the opposite side Keep the background visually clean and consistent so the performer remains the clear focus. No crowd. No backup dancers. No background distractions. No text. No logos. PERFORMANCE: She performs an energetic English rap directly into the camera with intense confidence and charisma. Her performance is physically expressive, stylish, aggressive, and rhythmically connected to the beat. Use dynamic upper-body movement: strong rhythmic shoulder movements fast hand gestures toward the lens pointing directly at the camera sweeping hand motions across the frame quick wrist movements expressive finger gestures arms moving in sync with the beat leaning very close to the camera quick upper-body shifts from left to right small forward lunges toward the lens sharp head nods sudden pauses followed by explosive movement She should feel like she is fully performing, not simply standing and lip-syncing. Her energy should be spontaneous, confident, intense, and natural. IMPORTANT: Even with aggressive gestures, her hands must never cover her mouth during spoken lyrics. Her face and lips must remain clearly visible throughout the performance. CAMERA WORK: Use highly dynamic, energetic music-video camera movement. The camera should feel physically involved in the performance. Include: fast handheld push-ins sudden pull-backs aggressive lateral camera sweeps quick low-angle movements rapid changes between tight close-up and medium close-up slight whip-pan transitions quick diagonal camera movements subtle Dutch-angle moments fast micro-orbits around her upper body sudden extreme close-ups during emphasized moments rhythmic forward and backward camera motion synchronized with the beat The camera movement should feel intense and raw, like a professional handheld hip-hop music video shoot. Allow occasional natural framing imperfections: partial shoulder cropping hands briefly passing close to the lens slight motion blur quick reframing natural handheld shake However, the camera must always recover quickly and keep her face readable. Do not use chaotic motion that makes the performer impossible to see. The camera motion should be aggressive but controlled. VOCAL PERFORMANCE: She performs an original English rap for most of the video, but not continuously for the full 30 seconds. Do not follow any predefined lyrics or narrative. The rap should sound natural, fluent, confident, rhythmic, and spontaneous, like a real freestyle performance. Use native-level English pronunciation with clear articulation and natural phrasing. The vocal delivery should include: confident rhythmic flow short punchy phrases natural pauses occasional emphasis slight changes in intensity expressive breath control Do not make the rap overly melodic. Do not turn it into singing. Do not use repetitive chanting. The vocal should feel like an authentic modern hip-hop freestyle rather than scripted recitation. Include brief non-rapping sections where she simply rides the beat. During these sections: the instrumental continues strongly she does not deliver full rap lyrics she stays in character and performs physically to the music she nods to the beat she moves her shoulders and upper body rhythmically she maintains confident eye contact with the camera she may smirk, breathe, laugh slightly, or give attitude she may use subtle ad-libs such as “yeah,” “uh,” or “let’s go” she must not continuously mouth nonexistent lyrics Suggested performance structure: 0–9 seconds: energetic English rap 9–13 seconds: no full rap, just riding the beat with physical performance and attitude 13–23 seconds: energetic English rap resumes 23–26 seconds: brief beat-only performance moment 26–30 seconds: final energetic rap section with strong ending attitude The transitions between rapping and non-rapping moments should feel natural and musical. LIP SYNC — CRITICAL: During rapped sections, lip synchronization must be exceptionally precise. Every spoken sound must correspond exactly to the visible mouth movement. Accurately reproduce: consonants vowels mouth openings lip closures jaw movement tongue movement where naturally visible breathing pauses emphasis rap rhythm There must be zero noticeable delay or drift between the generated vocal and visible mouth movement. The mouth must not move during silence unless there is a natural breath, reaction, smirk, or ad-lib. During non-rapping sections, do not create fake full-lyric mouth movement. Facial expressions must naturally follow the rhythm and intensity of the performance. Do not sacrifice lip-sync accuracy for camera movement. AUDIO: The vocal must remain clear and dominant, but the track should NOT feel like acapella. Use a heavy, dark, bass-driven hip-hop / trap instrumental throughout the full 30 seconds. The instrumental should include: very deep sub-bass powerful 808 bass hits punchy kick drums crisp hi-hats sharp snare hits dark atmospheric synth layers subtle distorted textures occasional bass drops low-frequency rumble sparse but cinematic transitions The bass should feel physically heavy and immersive, with strong low-end energy. Use a modern underground trap / drill-inspired sound, but keep it polished and cinematic rather than chaotic. Tempo: approximately 95–105 BPM. The beat should strongly support the rapper’s aggressive hand movements and camera motion. Synchronize major body movements, camera push-ins, whip pans, and emphasis moments with bass hits and beat drops. The music should have clear rhythmic structure: intro hit steady verse groove occasional heavier bass accents brief tension builds impactful drops The instrumental must continue throughout the entire 30 seconds, including the non-rapping sections. Do not use a thin or minimal instrumental. Do not let the track feel empty. Do not make it sound like spoken-word or acapella. The sub-bass and 808s should be clearly audible at all times, while still leaving enough space for the vocal. VOCAL MIX: Keep the female rap vocal centered, crisp, and intelligible. Use professional vocal mixing: slight compression subtle saturation controlled reverb very light delay clear presence in the midrange The vocal should sit naturally on top of the instrumental without overpowering it. Overall sound: dark, heavy, cinematic, club-ready, bass-rich, modern hip-hop. LIGHTING: Cinematic low-key lighting. Soft frontal key light keeps the face, eyes, and lips clearly visible at all times. Purple-magenta rim light from one side. Cool blue rim light from the opposite side. Fast camera movement creates changing reflections on jewelry and clothing. Natural skin texture. Realistic pores. No excessive beauty filtering. VISUAL STYLE: Premium contemporary hip-hop music video. Dark. Stylish. Aggressive. Raw. Intimate. High-energy. Cinematic. Ultra-photorealistic. Natural motion blur. Shallow depth of field. Realistic lens behavior. High dynamic range. Subtle filmic contrast. CRITICAL CONSISTENCY: Keep the same woman, same face, same hairstyle, same clothing, same accessories, and same studio environment throughout the entire 30 seconds. Do not introduce additional people. Do not change her identity. Do not change the background. Do not dramatically change the lighting setup. No subtitles. No captions. No logos. No watermark. No surreal effects. No facial deformation. No mouth distortion. No extra teeth. No incorrect lip movement.
