AI Music Video Generator

Create complete music videos: AI music + AI visuals + ffmpeg assembly.

Quick Start

"90년대 보이밴드 풍 한국어 노래 만들어줘" → music only
"발라드 뮤비 만들어줘" → music + slideshow MV
"EDM 뮤비 풀영상으로" → music + video clips MV
"Suno 뮤비로 만들어줘" → Suno native music video

Workflow

1. Plan scenes from lyrics/mood

Before generating, create prompts.json — array of scene descriptions derived from the song's lyrics, mood, and narrative. 8-12 scenes for a 3-min song.

[
  {"prompt": "Neon-lit city street at night, rain reflections", "type": "image"},
  {"prompt": "Camera slowly panning across a rooftop at sunset", "type": "video"},
  "A lone figure walking through cherry blossoms"
]

2. Generate music

bash scripts/suno_music.sh \
  --prompt "가사 또는 설명" \
  --style "90s boy band pop, korean" \
  --title "너만을 원해" \
  --model V4_5ALL --custom \
  --outdir /tmp/mv_project

Options:

• --model V4_5ALL (default), V5, V4_5PLUS, V4_5, V4
• --instrumental — no vocals
• --vocal-gender m|f — vocal gender hint
• --negative-tags "Heavy Metal, Drums" — styles to avoid
• --music-video — generate Suno native music video (MP4)
• --dry-run — cost check only

Persona (일관된 스타일 유지):

• --persona-id ID — 기존 페르소나 사용 (같은 보컬/스타일로 여러 곡 생성)
• --create-persona — 생성된 곡에서 페르소나 생성 → persona.json 저장
• --persona-name "이름" / --persona-desc "설명" / --persona-style "스타일"

Auto features:

• 🎤 Timestamped Lyrics: Non-instrumental tracks automatically fetch lyrics timestamps and save as {outdir}/lyrics.srt
• 🎬 Suno Native MV: With --music-video, Suno generates a visualized MP4 video directly
• 🎭 Persona: With --create-persona, extracts voice/style identity for reuse

3. Generate visuals (custom MV flow)

bash scripts/gen_visuals.sh \
  --mode slideshow \
  --prompts-file /tmp/mv_project/prompts.json \
  --image-provider seedream \
  --outdir /tmp/mv_project

Or with OpenAI (cheaper, lower res):

bash scripts/gen_visuals.sh \
  --mode slideshow \
  --prompts-file /tmp/mv_project/prompts.json \
  --image-provider openai --image-model gpt-image-1-mini --image-quality medium \
  --outdir /tmp/mv_project

Add --dry-run first to show cost estimate before spending.

4. Assemble

bash scripts/assemble_mv.sh \
  --audio /tmp/mv_project/track_0_xxx.mp3 \
  --outdir /tmp/mv_project \
  --output /tmp/mv_project/final_mv.mp4 \
  --transition fade

Subtitle behavior:

• Auto-detects {outdir}/lyrics.srt and overlays lyrics automatically
• --subtitle /path/to/custom.srt — use custom SRT file
• --no-subtitle — disable lyrics overlay entirely

Modes

Image cost is token-based — actual billing may be lower than listed estimates. Use --dry-run for precise cost.

Provider Options

Images: --image-provider seedream (recommended), openai, or google-together Image Model (OpenAI): --image-model gpt-image-1-mini (default, cheap) or gpt-image-1 (premium) Videos: --video-provider sora (default), sora-pro, seedance-lite, seedance-pro, veo-fast, veo-audio Quality: --image-quality low|medium|high

Cost Tracking

Every script outputs cost before and after. Always --dry-run first. Cost data saved to {outdir}/cost_estimate.json and {outdir}/visuals_meta.json.

Environment Variables

export SUNO_API_KEY="your-sunoapi-key"      # Required — sunoapi.org
export OPENAI_API_KEY="your-openai-key"     # Required — images + Sora video
export BYTEPLUS_API_KEY="your-byteplus-key" # Optional — Seedream 4.5 (recommended for images)
export TOGETHER_API_KEY="your-together-key" # Optional — Seedance, Veo, Imagen
export SUNO_CALLBACK_URL=""                 # Optional — see Callback URL below

⚠️ Required keys: SUNO_API_KEY and OPENAI_API_KEY must be set before running any script. BYTEPLUS_API_KEY is needed for Seedream image provider (sign up at console.byteplus.com, 200 free images). TOGETHER_API_KEY is only needed for Seedance/Veo/Imagen providers.

Callback URL

The Suno API requires a callBackUrl field for music generation requests. By default, if SUNO_CALLBACK_URL is not set, the script uses https://localhost/noop as a harmless no-op endpoint (an unreachable localhost URL that effectively disables callbacks).

To customize: set SUNO_CALLBACK_URL to your own endpoint, or set it to any dummy URL you control. The callback payload contains task metadata and audio URLs — no API keys are sent.

To disable: set SUNO_CALLBACK_URL=https://localhost/noop or any unreachable URL. Generation still works via polling; the callback is not required for the script to function.

Persona Workflow (채널 컨셉 유지)

YouTube 채널처럼 일관된 스타일로 여러 곡을 만들 때:

# 1. 첫 곡 생성 + 페르소나 만들기
bash scripts/suno_music.sh \
  --prompt "코드 리뷰하며 듣는 노래" \
  --style "indie rock, energetic, coding vibe" \
  --title "Pull Request" \
  --custom --create-persona \
  --persona-name "개발자 노동요 싱어" \
  --persona-desc "개발자가 코딩하며 듣기 좋은 에너지 넘치는 보컬. 인디록, 일렉, 팝 장르를 넘나든다." \
  --persona-style "indie rock, electronic, developer work music" \
  --outdir /tmp/dev-bgm-01

# 2. persona.json에서 personaId 확인
cat /tmp/dev-bgm-01/persona.json

# 3. 같은 페르소나로 다음 곡 생성 — 보컬/스타일 일관성 유지
bash scripts/suno_music.sh \
  --prompt "야근하면서 듣는 노래" \
  --style "electronic pop, night coding" \
  --title "Midnight Deploy" \
  --custom --persona-id <PERSONA_ID> \
  --outdir /tmp/dev-bgm-02

페르소나는 보컬 특성 + 음악 스타일을 기억해서, 채널 전체의 통일감을 유지해줌.
