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
| Mode | Visual | Best For | Cost (10 scenes) |
|---|
slideshow | AI images | Fast, cheap | ~$0.02 (mini low) / ~$0.09 (mini med) / ~$0.45 (Seedream) |
video | AI video clips | Premium | ~$1.40 (Seedance Lite) / ~$8.00 (Sora 2) |
hybrid | Mix of both | Balanced | ~$0.50-$4.00 |
suno-native | Suno MV | Easiest | Suno credits only |
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.
