   [ANCHOR]
   A Korean woman in her late 20s, long dark brown hair tied in a high ponytail with the tail falling over her right shoulder, a few loose strands framing her face. Clean glowing skin, natural dewy makeup, soft pink lip tint, defined slightly arched eyebrows, warm brown eyes, a gentle closed-lip smile. She wears a black tailored blazer over a plain white inner top, with a thin silver ring on her index finger. Soft pastel pink seamless studio background.
   
   [ACTION]
   She starts with her right hand resting lightly near her chin, then slowly lowers her hand as she begins speaking. A soft confident smile spreads across her face, she gives one small nod mid-sentence, and looks straight into the camera with a calm, friendly gaze.
   
   [CAMERA]
   Medium close-up from chest level, eye-level static shot, 85mm portrait lens look, very shallow depth of field, subject perfectly centered with slight space above her head.
   
   [LIGHTING]
   Soft large key light from the front, gentle fill bouncing back from the pink background, warm 4800K, beauty-portrait style, no harsh shadows, subtle catchlight in both eyes.
   
   [AUDIO]
   She speaks in clear, warm Korean with a polished broadcasting tone:
   "안녕하세요, 오늘은 영상 편집 앱 캡컷을 소개할게요."
   Lip movement precisely synced to Korean phonemes. Soft studio room tone, no background music, natural breath between phrases.
   
   [STYLE]
   Korean beauty-brand commercial aesthetic, clean and polished, soft pastel color palette, photorealistic 4K, natural skin texture preserved, 16:9 aspect ratio.
   
   [NEGATIVE]
   no English speech, no subtitles, no text overlays, no multiple people, no hair color change, no clothing change, no harsh shadows, no plastic skin, no distorted lip sync, no robotic voice, no logo watermarks, no extra fingers.

4. 변형 1 (밝은 튜토리얼 톤)

   [ACTION]
   She holds her right hand up at shoulder level with palm facing the camera in a gentle greeting wave, then brings both hands together at chest level as she finishes speaking. Bright open smile showing slight teeth, one cheerful nod.
   
   [LIGHTING]
   Bright high-key lighting from upper front and both sides, 5000K, slightly warmer than neutral, vibrant but soft, creator-vlog feel.
   
   [AUDIO]
   She speaks in upbeat, friendly Korean:
   "여러분 안녕하세요! 캡컷으로 영상 편집 시작해 볼까요?"
   Mouth movements tightly synced to Korean syllables. Quiet studio ambience, no music.

5. 변형 2 (차분한 리뷰 톤)

   [ACTION]
   She keeps her hands gently clasped at chest level throughout, slight head tilt to the right at the start, returns to center as she speaks. Composed thoughtful expression, soft closed-lip smile only at the end.
   
   [LIGHTING]
   Even soft front light, 5200K neutral, slight directional shadow on the left side of her face for depth, premium-magazine portrait feel.
   
   [AUDIO]
   She speaks in calm, measured Korean with a clear reviewer tone:
   "캡컷은 무료로 쓸 수 있는 영상 편집 도구예요."
   Lip movement precisely synced to Korean syllables. Subtle ambient room tone, no music.

1.2. 확장

Flow의 Extend 기능을 쓰면 이전 영상의 마지막 프레임이 자동으로 시작 프레임이 된다. 따라서 ANCHOR 블록은 외형을 길게 묘사하지 않고 "같은 인물·같은 의상·같은 배경"임을 짧게 명시하고, ACTION과 AUDIO에 집중하는 구조로 작성한다.

메인 프롬프트 (타임라인 개념 설명)

이전 영상 flow-capcut-host-v1의 끝 상태(손을 내리고 카메라 응시)에 이어 붙는 8초 컷이다.

[ANCHOR]
The same Korean woman from the previous shot, identical hairstyle, makeup, black tailored blazer over white inner top, soft pastel pink studio background. Continuous scene.

[ACTION]
She raises both hands to chest level, palms facing the camera, then slowly moves both hands horizontally from her left side to her right side as if drawing an invisible long bar in the air. She finishes with her right hand extended to the side and looks confidently at the camera with a small smile.

[CAMERA]
Medium close-up, eye-level static shot, 85mm portrait lens look, shallow depth of field. Same framing as the previous shot to keep visual continuity.

Identical to the previous shot. Soft large key light from the front, gentle pink fill from the background, warm 4800K, no harsh shadows.

[AUDIO]
She speaks in clear, friendly Korean with a polished broadcasting tone:

She speaks in clear, instructive Korean:
"왼쪽에서 오른쪽으로 시간이 흘러가요."
Lip movement precisely synced to Korean syllables. Soft studio room tone, no music.

[ACTION]
She holds her left palm out flat horizontally at chest level, then with her right hand makes a soft placing motion as if dropping rectangular blocks onto her left palm, twice. Finishes looking at the camera with an open smile.

"여기에 영상 클립을 순서대로 올려놓으면 돼요."
