Viral Video Studio

Full short-form video content creation workflow for TikTok, Instagram Reels, and YouTube Shorts: analyze a reference viral video URL, reverse-engineer its vi...

Security Scan

The skill's files and runtime instructions are coherent with its stated purpose (analyzing reference short videos and producing new short-form content), and it does not request unrelated credentials or install arbitrary code.

Purpose & Capability

The skill claims to analyze viral short videos and produce concepts/scripts/prompts. The included shell script (analyze_tiktok.sh) and SKILL.md steps explicitly call yt-dlp and ffmpeg to download and extract frames, and reference image- and video-generation services to create assets — these are consistent with the stated workflow.

Instruction Scope

The instructions tell the agent to download user-supplied TikTok URLs (yt-dlp) and extract frames to /tmp, then use the platform 'image' tool for analysis and generate prompts for external image/video services. This stays within the claimed purpose, but has privacy/legal implications: it will fetch potentially copyrighted creator content into /tmp and may send extracted frames to external analysis/generation endpoints. The SKILL.md does not instruct reading unrelated system files or environment variables.

Install Mechanism

No install spec is provided (instruction-only plus one helper script). No network downloads or archive extractions are embedded in an install step. The runtime assumes external tools (yt-dlp, ffmpeg, python3) are present on PATH; that is expected for the described operations.

Credentials

The skill does not declare or require any environment variables, credentials, or config paths. It references third-party services (Kling AI, Hailuo, DALL‑E) that the user may choose to sign up for, but the skill does not request secrets or tokens itself.

Persistence & Privilege

The skill is not forced-always, does not request autonomous privileges beyond the platform default, and does not modify other skills or system-wide settings. It writes outputs to project assets and /tmp as part of normal operation.

Assessment

This skill appears coherent for building short-form video workflows, but consider the following before installing: (1) It instructs the agent to run yt-dlp and ffmpeg to download and process a TikTok URL and save frames to /tmp — make sure you have permission to download/repurpose that content and check legal/copyright terms for the source and for any platform you publish to. (2) The workflow expects external AI services (DALL·E, Kling AI, Hailuo, etc.); you will need accounts/credentials for those and any uploaded images/character references will be shared with those services. (3) Ensure yt-dlp/ffmpeg/python3 are available on the host; the script assumes those binaries. (4) The skill contains monetization/affiliate guidance — review any affiliate links or claims and be cautious about sharing personal account credentials. If you want a higher-assurance review, provide any additional hidden files or a list of external endpoints the skill will call at runtime (e.g., specific API URLs/SDKs) so I can check for unexpected network exfiltration or requests for unrelated secrets.

End-to-end workflow for cloning viral TikTok content structure and building a monetizable channel.

Step 0: Define Character (Do This Once)

Before making any video, create a Character Bible. Read references/character-bible.md.

Key decisions:

1. Pick archetype: Overconfident Underdog / Dignified Aristocrat / Innocent Explorer / Unlikely Professional
2. Define: species, color, signature outfit, personality, fatal flaw, motivation
3. Write a "consistency prompt prefix" — prepend to EVERY AI image prompt
4. Choose series format: single gags OR running series (series = faster follower growth)

Output: A completed character sheet saved to assets/character-sheet.md See assets/character-sheet-template.md for the fill-in-the-blank template.

Step 1: Analyze Reference Video

When user provides a TikTok URL:

# Download video
yt-dlp -o "/tmp/tiktok-ref.%(ext)s" "<URL>"

# Extract first frame for visual analysis
ffmpeg -i /tmp/tiktok-ref.mp4 -ss 00:00:01 -frames:v 1 /tmp/tiktok-thumb.jpg -update 1

# Try to get subtitles (may not be available)
yt-dlp --write-auto-sub --sub-lang "vi,en,zh" --skip-download -o "/tmp/tiktok-sub" "<URL>"

Then use the image tool to analyze /tmp/tiktok-thumb.jpg and describe:

• Content type: Comedy / Educational / Story / Trend
• Format: AI-generated images / Live action / Screen recording / Animation
• Hook style: Text hook / Visual hook / Sound hook
• Pacing: Fast cuts / Slow / Building
• Emotion trigger: Humor / Surprise / Curiosity / Relatability

---

Step 2: Deep Viral Analysis

This is the most important step. Read references/viral-analysis.md for full protocol.

Quick analysis (run for every reference video):

1. 7 Triggers check — which psychological triggers fire? (surprise, relatability, curiosity, social currency, empathy, awe, identity)
2. Frame-by-frame breakdown — what emotion does each moment create?
3. The Real Why — what universal human experience is at the core?
4. Share mechanic — who sends this to whom, and why?
5. Red flags check — does the reference video have any fail patterns to avoid?

Output a Viral Analysis Report (template in viral-analysis.md) before writing any script.

---

Step 3: Reverse-Engineer Viral Structure

Decode the video into this framework:

HOOK (0-3s):     What stops the scroll?
SETUP (3-10s):   What's the premise?
CONFLICT (10-25s): What's the tension/challenge?
PEAK (25-35s):   What's the climax?
TWIST (35-45s):  Surprise or punchline
CTA (45-55s):    What action does it ask for?

Identify:

• Character archetype: Small vs Big / Underdog / Relatable everyman
• Emotion arc: Anticipation → Tension → Release → Satisfaction
• Loop factor: Does it make viewers rewatch? How?

---

Step 4: Generate New Video Concept

Create a new video using the SAME structure but DIFFERENT content:

Concept generation prompt:

Based on this viral structure: [DECODED STRUCTURE]
Generate 5 new video concepts using the same emotional arc but different characters/scenarios.
Each concept: Title + Character + Scenario + Twist
Format: AI-generated image series (6 frames)

Pick the best concept and proceed.

---

Step 5: Scene-by-Scene AI Image Prompts

For each of the 6 frames, write Midjourney/DALL-E prompts following this formula:

[Subject] [Action] [Setting] [Emotion] [Style: photorealistic/cartoon/cinematic] [Aspect ratio: 9:16 vertical]

Quality modifiers to always include:

• photorealistic, ultra detailed, professional photography
• 9:16 vertical format (TikTok native)
• dramatic lighting or soft natural lighting
• funny expression / shocked expression / confident pose

Consistency tip: Start each prompt with "Same [character description]" to maintain visual consistency across frames.

🎀 Cute Factor: Cute characters — chubby body, round shape, big eyes — create instant emotional investment. The cuter the character, the faster viewers bond and the harder they laugh at failures. Lean into exaggerated cuteness. See references/character-bible.md for the Cute Factor framework.

Video generation options (choose by budget):

• Budget: DALL-E images → CapCut slideshow (~$0.50/video)
• Mid: Hailuo AI video clips → CapCut (~$0.75/video)
• Best quality: Kling AI with character reference image (~$1-3/video)
• See references/video-generation-tools.md for full comparison, pricing, and all 15 Kling AI prompts for Hammy video.

Step 6: Full Scene-by-Scene Script

For EVERY scene (frame), specify ALL of the following in detail:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CẢNH [N] — [TIMESTAMP, e.g. 0:00-0:03]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

👁️ HÌNH ẢNH (Visual):
  - Nhân vật: [Ai? Đang làm gì? Biểu cảm gì? Tư thế?]
  - Bối cảnh: [Địa điểm, ánh sáng, góc máy]
  - Chuyển động: [Static / Ken Burns zoom in / Ken Burns zoom out / Pan]
  - Chi tiết quan trọng: [Vật thể nào nổi bật? Màu sắc chủ đạo?]

🎨 DALL-E / MIDJOURNEY PROMPT:
  "[Character description], [action], [setting], [emotion], [lighting], photorealistic, 9:16 vertical"
  Negative prompt: "blurry, deformed, text, watermark"

📝 TEXT OVERLAY:
  Nội dung: "[Tối đa 6 từ + emoji]"
  Vị trí: [Top / Bottom / Center]
  Font style: [Bold white + black stroke]

🔊 ÂM THANH:
  Nhạc nền: [Tên loại nhạc / mood: sneaky / dramatic / happy / sad...]
  SFX: [Tên sound effect cụ thể: "record scratch" / "vine boom" / "sad trombone" / không có]
  Volume nhạc: [100% / 70% / 50%]

⏱️ THỜI LƯỢNG: [X giây]
🎭 CẢM XÚC MỤC TIÊU: [Người xem cảm thấy gì ở cảnh này?]
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Ví dụ cảnh chi tiết:

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
CẢNH 1 — 0:00-0:03 (HOOK)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

👁️ HÌNH ẢNH:
  - Nhân vật: Hammy (hamster béo màu cam) đứng thẳng, hai tay chống hông
    Biểu cảm: Tự tin, mắt ánh lên quyết tâm
    Tư thế: Nhìn thẳng vào camera, ngực ưỡn ra
  - Bối cảnh: Trước cổng ngân hàng khổng lồ, góc máy thấp nhìn lên
    Ngân hàng cao như tòa nhà chọc trời so với Hammy
  - Chuyển động: Ken Burns zoom out chậm để lộ kích thước ngân hàng
  - Chi tiết: Ánh nắng buổi sáng, bóng Hammy dài trên mặt đường

🎨 DALL-E PROMPT:
  "Hammy, a tiny chubby round orange hamster with big black eyes,
  wearing yellow cherry-print shorts, standing confidently arms akimbo
  in front of a massive marble bank building that towers above him,
  dramatic low angle shot, morning golden light, photorealistic, 9:16 vertical"
  Negative: "blurry, deformed, text, watermark, multiple characters"

📝 TEXT OVERLAY:
  Nội dung: "Hammy có kế hoạch 😤"
  Vị trí: Bottom 1/3
  Font: Bold white + black stroke, size lớn

🔊 ÂM THANH:
  Nhạc nền: Spy/sneaky piano theme (bắt đầu nhẹ)
  SFX: Dramatic single piano chord khi text hiện ra
  Volume nhạc: 60%

⏱️ THỜI LƯỢNG: 3 giây
🎭 CẢM XÚC: Tò mò + hào hứng — "Cái gì đây?!"
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Quy tắc âm thanh theo từng loại cảnh:

Loại cảnh	Nhạc nền	SFX gợi ý
HOOK	Dramatic sting / Silence → bang	Single piano chord
SETUP	Sneaky/spy theme	Footsteps, paper rustle
CONFLICT	Tension buildup	Machine hum, creaking
PEAK	Music STOPS → chaos	Explosion, scream
TWIST	Sad trombone / Magic sparkle	Record scratch, fail horn
CTA	Upbeat happy	Victory fanfare (mini)

Quy tắc hình ảnh đa frame → video:

Mỗi video = 6-15 frames ảnh AI ghép thành video trong CapCut:

• Frame 1-2: HOOK (3-6 giây)
• Frame 3-5: SETUP + CONFLICT (10-15 giây)
• Frame 6-8: PEAK (8-10 giây)
• Frame 9-10: TWIST (5-7 giây)
• Frame 11-12: RESOLUTION + CTA (5-7 giây)

Ken Burns effect trên mỗi frame tạo cảm giác chuyển động dù ảnh tĩnh:

• Zoom in: tạo tension, dramatic
• Zoom out: reveal surprise
• Pan left/right: following character movement

Step 7: Algorithm Optimization

TikTok ranks videos by priority order:

1. Completion rate — watch to the end? (most important)
2. Rewatch rate — watch again?
3. Shares — send to someone?
4. Comments — feel compelled to respond?
5. Follows — earn new followers?

Every creative decision must serve one of these metrics.

Hook Formulas (First 3 Seconds — Most Critical)

"Stop scrolling if you [situation]"
"POV: [character] just discovered [thing]"
"Watch until the end — [teaser of twist]"
"[Bold statement]. Let me explain."
"[Number] things about [topic] nobody talks about:"

Video Length Strategy

• 7-15s: Memes, single-gag AI images → highest completion rate
• 15-30s: Story arc (6 frames) → best balance of value + retention
• 30-60s: Extended story, series episode → loyal audience
• 1-3 min: Deep dives → lower reach but higher-quality followers

Engagement Tactics

• Reply to every comment in first hour → algorithm boost
• Pin the funniest comment on each video
• Create follow-up videos responding to comments
• Ask a specific question in CTA (not generic "comment below")
• Use "Part 2?" as CTA to tease continuation

---

Step 8: CapCut Assembly Instructions

1. Import all AI images in order
2. Set each image duration: 3-5 seconds
3. Add Ken Burns effect (slow zoom) on each image
4. Add transition: Fade or Whip Pan between frames
5. Add text overlay per frame (match script)
6. Add background music: search "sneaky/funny/dramatic" in CapCut sounds
7. Add sound effects at TWIST frame (e.g., "record scratch", "dramatic chipmunk")
8. Export: 1080x1920, 30fps, MP4
