You combine AI-sourced reaction hooks, intelligent demo analysis, professional video editing, and automated publishing into a single pipeline. **The Pipeline:** ``` DanSUGC (hooks + analytics) + Demos (analyzed by Gemini) + Text + Music | FFmpeg Assembly | Post-Bridge Scheduling | DanSUGC Analytics Proxy (tracking) | Replicate Winners ``` ## References Load these reference files when you need detailed specs for each area: - `references/tools-setup.md` — How to set up DanSUGC, Post-Bridge, and Gemini - `references/green-zone.md` — Platform safe areas and text positioning specs - `references/ffmpeg-patterns.md` — All ffmpeg commands for trimming, scaling, text, concat, music - `references/virality.md` — Duration rules, hook writing, caption formulas, output specs ## Critical Rules 1. **MAX 15 SECONDS per reel** — non-negotiable for virality 2. **ALL text MUST use TikTok Sans font** — no exceptions 3. **ALL text MUST be in the Green Zone** — never in platform UI areas 4. **ONE video per ONE account** — never schedule the same video to multiple accounts 5. **Always run Preflight (Step 0) first** — verify all tools before work 6. **Always use Gemini 3.1 Flash Lite for video intelligence** — model: `gemini-3.1-flash-lite-preview` 7. **Never expose API keys in output** — redact in logs, never print full keys 8. **Purchase videos from DanSUGC before downloading** — users must purchase clips via the MCP tool before getting download URLs --- ## Step 0: Preflight Check (MANDATORY) Run this EVERY time before doing any work. Check all tools, fonts, and MCP connections. ### 0a. FFmpeg & FFprobe ```bash if command -v ffmpeg &>/dev/null; then echo "ffmpeg: OK ($(ffmpeg -version 2>&1 | head -1))" else echo "ffmpeg: MISSING — installing..." if command -v brew &>/dev/null; then brew install ffmpeg elif command -v apt-get &>/dev/null; then sudo apt-get update && sudo apt-get install -y ffmpeg else echo "ERROR: Install ffmpeg manually"; exit 1 fi fi command -v ffprobe &>/dev/null && echo "ffprobe: OK" || echo "ffprobe: MISSING" ``` ### 0b. TikTok Sans Font TikTok Sans is TikTok's official open-source font (SIL Open Font License 1.1). Required for all text overlays. ```bash if [ -f "$HOME/Library/Fonts/TikTokSansDisplayBold.ttf" ] || [ -f "/usr/share/fonts/TikTokSansDisplayBold.ttf" ] || [ -f "$HOME/.local/share/fonts/TikTokSansDisplayBold.ttf" ]; then echo "TikTok Sans: OK" else echo "TikTok Sans: MISSING — installing..." if [[ "$(uname)" == "Darwin" ]]; then FONT_DIR="$HOME/Library/Fonts" else FONT_DIR="$HOME/.local/share/fonts" fi mkdir -p "$FONT_DIR" cd /tmp curl -L -o tiktoksans.zip "https://www.cufonfonts.com/download/font/tiktok-sans" unzip -o tiktoksans.zip -d tiktoksans_extracted cp tiktoksans_extracted/TikTokSans*.ttf "$FONT_DIR/" rm -rf tiktoksans_extracted tiktoksans.zip command -v fc-cache &>/dev/null && fc-cache -f "$FONT_DIR" echo "TikTok Sans: installed to $FONT_DIR" fi ``` ### 0c. MCP Connections Verify required MCP servers are connected. If missing, load `references/tools-setup.md` for setup instructions. ``` Required MCP Servers: dansugc — mcp__dansugc__search_videos (UGC reaction hooks + analytics proxy) post-bridge — mcp__post-bridge__list_social_accounts (publishing) ``` ### 0d. Gemini API Key ```bash if [ -n "$GEMINI_API_KEY" ]; then echo "Gemini API: OK (key set)" else echo "Gemini API: MISSING — set GEMINI_API_KEY environment variable" echo "Get your key at: https://aistudio.google.com/apikey" fi ``` ### 0e. Preflight Summary ```bash echo "=== REELCLAW PREFLIGHT ===" echo "ffmpeg: $(command -v ffmpeg &>/dev/null && echo 'OK' || echo 'MISSING')" echo "ffprobe: $(command -v ffprobe &>/dev/null && echo 'OK' || echo 'MISSING')" FONT_OK="MISSING" for dir in "$HOME/Library/Fonts" "$HOME/.local/share/fonts" "/usr/share/fonts"; do [ -f "$dir/TikTokSansDisplayBold.ttf" ] && FONT_OK="OK" && break done echo "TikTok Sans: $FONT_OK" echo "Gemini API: $([ -n \"$GEMINI_API_KEY\" ] && echo 'OK' || echo 'MISSING')" echo "=============================" ``` **All must show OK before proceeding.** --- ## Step 1: Source UGC Hooks from DanSUGC Search for reaction clips matching your content's emotional tone. The best hooks are emotionally charged reactions. ### Emotion Categories (ranked by engagement) | Emotion | Best For | Search Terms | |---------|----------|-------------| | **Shocked** | Surprising reveals, stats | `shocked surprised reaction` | | **Crying/Tears** | Emotional stories, relatable pain | `crying sad tears emotional` | | **Frustrated** | Problem-agitate-solve content | `frustrated overwhelmed stressed` | | **Angry** | Injustice, call-to-action | `angry upset outraged` | | **Happy/Excited** | Wins, positive outcomes | `happy excited celebrating` | | **Confused** | Educational content, myth-busting | `confused puzzled thinking` | ### Search Strategy Use **semantic search** for best results: ``` mcp__dansugc__search_videos(semantic_search="shocked woman reacting to phone screen") mcp__dansugc__search_videos(emotion="shocked", gender="female", limit=10) mcp__dansugc__search_videos(semantic_search="crying emotional reaction", min_virality=75) ``` ### Purchase & Download Workflow 1. **Search** for matching clips 2. **Review** results — check duration, emotion, virality score 3. **Check balance** with `mcp__dansugc__get_balance` 4. **Purchase** selected clips with `mcp__dansugc__purchase_videos` 5. **Download** using the URLs returned from purchase ```bash curl -L -o hook-clip.mp4 "DOWNLOAD_URL_FROM_PURCHASE" ``` ### Hook Selection Rules - **Duration:** Prefer clips 5-14 seconds (will be trimmed to ~5s) - **Virality score:** Prefer 70+ for proven engagement - **Emotion match:** Match the hook emotion to the text overlay emotion - **Vertical preferred:** 1080x1920 clips need no cropping - **Landscape OK:** Will be center-cropped to vertical --- ## Step 2: Analyze & Split Demos with Gemini Use Gemini 3.1 Flash Lite to analyze app demo recordings and extract the best segments. ### 2a. Extract Keyframes ```bash ffmpeg -y -hide_banner -loglevel error \ -i "DEMO.mp4" \ -vf "fps=1/5,scale=540:-1" \ "keyframes/frame_%03d.jpg" ``` ### 2b. Gemini Video Analysis ```bash # Direct video upload to Gemini (preferred) FILE_URI=$(curl -s -X POST \ "https://generativelanguage.googleapis.com/upload/v1beta/files?key=$GEMINI_API_KEY" \ -H "X-Goog-Upload-Command: start, upload, finalize" \ -H "X-Goog-Upload-Header-Content-Type: video/mp4" \ -H "Content-Type: video/mp4" \ --data-binary @"DEMO.mp4" | python3 -c "import sys,json; print(json.load(sys.stdin)['file']['uri'])") curl -s "https://generativelanguage.googleapis.com/v1beta/models/gemini-3.1-flash-lite-preview:generateContent?key=$GEMINI_API_KEY" \ -H "Content-Type: application/json" \ -d "{ \"contents\": [{ \"parts\": [ {\"text\": \"Analyze this app demo. Identify the best 7-9 second clips and 20-30 second segments for speed-up. Return JSON array with: {name, start_sec, end_sec, type: 'short'|'speedup', description}\"}, {\"file_data\": {\"file_uri\": \"$FILE_URI\", \"mime_type\": \"video/mp4\"}} ] }], \"generationConfig\": {\"temperature\": 0.2, \"response_mime_type\": \"application/json\"} }" ``` ### 2c. Auto-Cut Clips For detailed ffmpeg patterns for trimming, scaling, speed-up, and concat, load [./references/ffmpeg-patterns.md](./references/ffmpeg-patterns.md). **Short clips (natural speed, 7-9s):** ```bash VF="scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:color=black,fps=30" ffmpeg -y -hide_banner -loglevel error \ -i "DEMO.mp4" -ss START -to END \ -vf "$VF" -an \ -c:v libx264 -preset fast -crf 18 -movflags +faststart \ "clips/short/CLIP_NAME.mp4" ``` **Speed-up clips (20-30s source -> 7-9s output) — MUST use two-pass:** ```bash # Pass 1: Trim segment ffmpeg -y -hide_banner -loglevel error \ -i "DEMO.mp4" -ss START -to END \ -c copy "/tmp/segment.mp4" # Pass 2: Speed up + scale (e.g., 30s -> 8.5s = setpts=0.283*PTS) ffmpeg -y -hide_banner -loglevel error \ -i "/tmp/segment.mp4" \ -vf "setpts=0.283*PTS,$VF" -an \ -c:v libx264 -preset fast -crf 18 -movflags +faststart \ "clips/speedup/CLIP_NAME.mp4" ``` ### 2d. Build Clip Library ``` project/ clips/ short/ # 7-9s natural speed clips speedup/ # 7-9s sped-up clips hooks/ # Downloaded UGC reaction clips finals/ # Completed reels music/ # Audio tracks clip-manifest.md # Index of all clips with descriptions ``` --- ## Step 3: Assemble Reels Combine hooks + demos + text + music into 15-second reels. ### 3a. The 15-Second Formula ``` Hook clip: ~5 seconds (UGC reaction — attention grabber) Demo clip: ~10 seconds (app demo — the product showcase) Total: 15 seconds MAX ``` ### 3b. Prepare Hook Clip **Landscape source (center crop):** ```bash ffmpeg -y -hide_banner -loglevel error \ -i "hook.mp4" -ss 1 -to 6 \ -vf "scale=1080:1920:force_original_aspect_ratio=increase,crop=1080:1920,setsar=1,fps=30" \ -an -c:v libx264 -preset fast -crf 18 -movflags +faststart \ "hook-trimmed.mp4" ``` **Vertical source (scale + pad):** ```bash ffmpeg -y -hide_banner -loglevel error \ -i "hook.mp4" -ss 1 -to 6 \ -vf "scale=1080:1920:force_original_aspect_ratio=decrease,pad=1080:1920:(ow-iw)/2:(oh-ih)/2:color=black,setsar=1,fps=30" \ -an -c:v libx264 -preset fast -crf 18 -movflags +faststart \ "hook-trimmed.mp4" ``` ### 3c. Concatenate Hook + Demo ```bash cat > /tmp/concat.txt << EOF file 'hook-trimmed.mp4' file 'demo-trimmed.mp4' EOF ffmpeg -y -hide_banner -loglevel error \ -f concat -safe 0 -i /tmp/concat.txt \ -c:v libx264 -preset fast -crf 18 -movflags +faststart \ "reel-notext.mp4" ``` ### 3d. Add Text Overlays **ALL text must use TikTok Sans and be placed within the Green Zone.** For full specs, load [./references/green-zone.md](./references/green-zone.md). **For text WITH apostrophes** — use `textfile=` to avoid escaping issues: ```bash printf "When nothing's wrong" > /tmp/hook_line1.txt ffmpeg -y -hide_banner -loglevel error -i "reel-notext.mp4" \ -vf "drawtext=textfile=/tmp/hook_line1.txt:\ fontfile=$HOME/Library/Fonts/TikTokSansDisplayBold.ttf:\ fontsize=64:fontcolor=white:borderw=4:bordercolor=black:\ x=(60+(900-text_w)/2):y=310:\ enable='between(t,0,4.5)'" \ -c:v libx264 -preset fast -crf 18 -c:a copy -movflags +faststart \ "reel-text.mp4" ``` **For text WITHOUT apostrophes** — use inline `text=`: ```bash ffmpeg -y -hide_banner -loglevel error -i "reel-notext.mp4" \ -vf "drawtext=text='All this worrying':\ fontfile=$HOME/Library/Fonts/TikTokSansDisplayBold.ttf:\ fontsize=64:fontcolor=white:borderw=4:bordercolor=black:\ x=(60+(900-text_w)/2):y=310:\ enable='between(t,0,4.5)'" \ -c:v libx264 -preset fast -crf 18 -c:a copy -movflags +faststart \ "reel-text.mp4" ``` **Escape colons in drawtext with `\\:`** (e.g., "10\\:00 AM"). ### 3e. Add Music ```bash ffmpeg -y -hide_banner -loglevel error \ -i "reel-text.mp4" -i "track.mp3" \ -map 0:v -map 1:a \ -af "afade=t=in:st=0:d=0.5,afade=t=out:st=14:d=1,volume=0.8" \ -c:v copy -c:a aac -b:a 128k \ -shortest -movflags +faststart \ "reel-final.mp4" ``` ### 3f. Validate Duration (MANDATORY) ```bash ffprobe -v quiet -print_format json -show_entries format=duration "reel-final.mp4" | \ python3 -c "import sys,json; d=float(json.load(sys.stdin)['format']['duration']); \ print(f'Duration: {d:.1f}s — {\"OK\" if d <= 15.0 else \"TOO LONG — must re-edit\"}')" ``` **If over 15.0s:** trim the demo clip or speed it up. NEVER deliver over 15 seconds. --- ## Step 4: Publish via Post-Bridge For full setup instructions, load [./references/tools-setup.md](./references/tools-setup.md). ### 4a. Upload Videos Videos need public URLs. Use tmpfiles.org for temporary hosting: ```bash url=$(curl -s -F "file=@reel-final.mp4" https://tmpfiles.org/api/v1/upload | \ python3 -c "import sys,json; u=json.load(sys.stdin)['data']['url']; \ print(u.replace('tmpfiles.org/', 'tmpfiles.org/dl/'))") echo "Public URL: $url" ``` ### 4b. Schedule Posts ``` mcp__post-bridge__create_post( caption="Hook text...\n\nCaption body...\n\n#hashtag1 #hashtag2 #fyp", social_accounts=[ACCOUNT_ID], media_urls=["PUBLIC_VIDEO_URL"], scheduled_at="2026-03-10T22:00:00Z" ) ``` **Distribution rules:** - ONE unique video per account — never post the same video to multiple accounts - Stagger posting times by 5 minutes between accounts - Drafts (`is_draft: true`) cannot be updated/deleted via API ### 4c. Caption Formula ``` [Hook text — the emotional line from the video] [1-2 sentences connecting the emotion to your product/solution] #hashtag1 #hashtag2 #hashtag3 #hashtag4 #hashtag5 #fyp ``` --- ## Step 5: Track Performance via DanSUGC Analytics Proxy Social media analytics are included with your DanSUGC API key — no extra setup needed. DanSUGC proxies ScrapCreators data at `$0.02/request` from your existing balance. Auth is handled automatically by the MCP server. ``` # Get TikTok video stats mcp__dansugc__scrapecreators_raw(path="v1/tiktok/video", params={url: "VIDEO_URL"}) # Search TikTok videos by keyword mcp__dansugc__tiktok_search_videos(query="KEYWORD") # Get TikTok profile videos (sorted by popular) mcp__dansugc__tiktok_user_videos(handle="USERNAME", sort_by="popular") # Search Instagram reels mcp__dansugc__instagram_search_reels(query="KEYWORD") ``` **Error codes:** - `402` — Insufficient DanSUGC balance (top up credits) - `403` — API key not linked to a user account - `502` — Upstream unreachable (auto-refunded, safe to retry) ### Winner Thresholds (24-48h) | Metric | Good | Great | Viral | |--------|------|-------|-------| | Views | 10K+ | 100K+ | 1M+ | | Like ratio | 5%+ | 10%+ | 15%+ | | Comment ratio | 0.5%+ | 1%+ | 2%+ | | Share ratio | 0.3%+ | 1%+ | 3%+ | ### Replicate Winners 1. Same hook emotion + different UGC creator 2. Same text style + same demo angle 3. Same music + spread across accounts 4. Search for more clips: `mcp__dansugc__search_videos(emotion="shocked", min_virality=70)` --- ## Step 6: Format Research — Find Viral Formats for Any Niche When users ask for format ideas (e.g., "find me format ideas for beef liver supplements on TikTok"), use the DanSUGC MCP tools to research what's working in that niche across TikTok and Instagram. ### 6a. Search for Niche Content Search TikTok and Instagram for top-performing content in the user's niche: ``` # Search TikTok for niche keywords mcp__dansugc__tiktok_search_videos(query="NICHE_KEYWORD") # Search Instagram reels for same niche mcp__dansugc__instagram_search_reels(query="NICHE_KEYWORD") ``` **Run multiple keyword variations** to cast a wider net. For example, for "beef liver supplements": - `beef liver supplement` - `beef liver capsules` - `organ supplements` - `liver king` (known creators in the niche) - `desiccated liver` ### 6b. Find Top Creators in the Niche Identify creators who are crushing it, then pull their most popular videos: ``` # Search for creators in the niche mcp__dansugc__tiktok_search_users(query="NICHE_KEYWORD") # Get their top-performing videos mcp__dansugc__tiktok_user_videos(handle="CREATOR_USERNAME", sort_by="popular") # Get Instagram creator reels mcp__dansugc__instagram_user_reels(handle="CREATOR_USERNAME") ``` ### 6c. Analyze & Present Format Ideas From the search results, extract and present **4-5 distinct format ideas**. For each format: ```markdown ### Format [N]: [Format Name] **Description:** What the format looks like and how it works **Example:** [Link or description of a top-performing video using this format] **Stats:** [Views, likes, engagement rate from the search results] **Why it works:** [Brief psychology — why this format resonates] **How to replicate with ReelClaw:** - Hook type: [emotion — shocked, crying, etc.] - Text hook style: [e.g., "When..." question, bold statement, statistic] - Demo content: [what to show in the demo portion] - Music vibe: [energetic, moody, trending sound] ``` ### 6d. Format Research Strategy **Search in this order for best results:** 1. **Broad niche search** — `keyword search` for the main niche term 2. **Specific product search** — `keyword search` for the exact product/brand 3. **Creator discovery** — `user search` to find niche influencers 4. **Creator deep-dive** — `profile videos sorted by popular` for top 2-3 creators 5. **Cross-platform** — Repeat key searches on Instagram for format diversity **What to look for in results:** - Videos with unusually high engagement (likes/views ratio > 10%) - Recurring formats across multiple creators (validates the format works) - Content styles: UGC reactions, before/after, POV, tutorials, testimonials, unboxing, "day in my life" - Hook patterns: text overlays, opening lines, visual hooks - Duration sweet spots in the niche --- ## Step 7: Hook Research — Find Winning Text Hooks When users ask for hook ideas, use the DanSUGC MCP tools to find text hooks proven to work in the niche. ### 7a. Search for Hook Inspiration ``` # Search TikTok for niche content — hooks live in video descriptions/captions mcp__dansugc__tiktok_search_videos(query="NICHE_KEYWORD") # Search with emotional angle keywords mcp__dansugc__tiktok_search_videos(query="NICHE relatable") # Instagram reels for different hook styles mcp__dansugc__instagram_search_reels(query="NICHE_KEYWORD") ``` ### 7b. Extract & Categorize Hooks From the search results, extract text hooks from video descriptions, captions, and titles. Group them by type: | Category | Pattern | Example | |----------|---------|---------| | **"When..." hooks** | When [relatable situation]... | "When you've tried everything but nothing works" | | **POV hooks** | POV: [scenario] | "POV: you finally tried organ supplements" | | **Statistic hooks** | [Number] [claim] | "90% of people are deficient in this" | | **Question hooks** | [Provocative question]? | "Why is nobody talking about this?" | | **Confession hooks** | I [honest admission] | "I used to think supplements were a scam" | | **"Nobody..." hooks** | Nobody talks about [truth] | "Nobody tells you this about iron deficiency" | | **Challenge hooks** | [Dare or challenge] | "Try this for 30 days and watch what happens" | | **Before/After hooks** | [Before state] → [After state] | "Day 1 vs Day 30 on beef liver" | ### 7c. Present Hook Ideas For each hook, provide: ```markdown ### Hook [N]: "[The hook text]" **Category:** [Hook type from table above] **Inspired by:** [Video from search results with stats] **Emotion:** [What UGC reaction to pair with — shocked, curious, crying, etc.] **Text overlay format:** Line 1: [first line of text] Line 2: [second line, if needed] **Matching caption:** [Full caption including hashtags] ``` ### 7d. Hook Research Strategy **To find hooks that match a specific format:** 1. Search for the format keyword (e.g., "supplement review TikTok") 2. Look at the top 10-20 results 3. Extract the first line of each caption — this is usually the hook 4. Cross-reference with engagement: hooks from high-performing videos are proven **To find hooks for a specific brand/product:** 1. Search for the brand name directly 2. Search for the product category + emotional keywords 3. Search for competitor brand names **Hook quality signals:** - High engagement ratio (likes/views > 10%) - Many comments (comments indicate the hook triggered a response) - Hook text matches the emotional tone of the video - Short and scannable (3-7 words per line, max 3 lines) --- ## Troubleshooting **"No token data found" for DanSUGC MCP:** - Re-register: `claude mcp add --transport http -s user dansugc https://dansugc.com/api/mcp -H "Authorization: Bearer YOUR_KEY"` - Restart Claude Code after adding **Apostrophes breaking text overlays:** - Use `textfile=/tmp/mytext.txt` instead of inline `text='...'` - Write text to file first: `printf "don't stop" > /tmp/mytext.txt` **Speed-up clips output wrong duration:** - Always use two-pass: trim first with `-c copy`, then speed up with `setpts` - Never combine `-ss`/`-to` with `setpts` in a single pass **Drafts can't be updated/deleted in Post-Bridge:** - API limitation — drafts are immutable. Create a new scheduled post instead. **Text cut off by platform UI:** - Check Green Zone specs in [./references/green-zone.md](./references/green-zone.md) - Y must be between 210 and 1480, X between 60 and 960 (universal)
