Clone Ad

clone-ad

The full pipeline for cloning a winning ad end-to-end — fetch reference, extract shot list with Gemini, generate product image with Nano Banana 2, generate cloned ad with Seedance 2.0, verify shot density, ship.

When to invoke

• The user has seen an ad that performs and wants to clone its pacing/structure for their own product
• They want a 15-second 9:16 vertical video with native audio (talking-head, UGC, product demo)
• They don't want to film, edit in a timeline, or stitch separate voice generations on top — one image-to-video call should produce the whole piece
• The reference is a public URL (Meta Ad Library / TikTok / Instagram / YouTube) or a local MP4 they can point to

Not this skill: if the user wants a single TikTok's motion recreated on a different character (same moves, same sound, new face) rather than a reference ad's pacing/shot structure rebuilt for a different product, use the sibling skill vidjutsu-clone instead — it drives only the VidJutsu API (no WaveSpeed/Gemini keys) end to end from a TikTok URL.

Required environment variables

• WAVESPEED_API_KEY — required. Used for both Nano Banana 2 (product image) and Seedance 2.0 (video).
• GEMINI_API_KEY — required. Used to analyze the reference video and extract a structured shot list.
• SCRAPE_CREATORS_API — required for Meta Ad Library / TikTok / Instagram references. NOT required for YouTube (Gemini fetches YouTube URLs directly) or local files.

The pipeline (7 steps)

Read each recipe in order. Every recipe is a self-contained markdown file under recipes/.

1. Fetch the reference → recipes/01-fetch-reference.md — resolve URL to a usable media source
2. Extract the shot list → recipes/02-extract-shot-list.md — Gemini analyze → structured JSON
3. Generate product image → recipes/03-generate-product-image.md — Nano Banana 2 hero shot (skip if user already has one)
4. Rewrite shot list for the product → recipes/04-rewrite-shot-list-for-product.md — substitute product + dialogue, hold the framing/angle/movement variety
5. Generate the clip → recipes/05-generate-clip.md — Seedance 2.0 image-to-video, 15s @ 480p 9:16
6. Verify the clone → recipes/06-verify-clone.md — re-analyze the output, compare shot density
7. Iterate or ship → recipes/07-iterate-or-ship.md — remediate prompt and regenerate, or call it done

Working directory layout

Set up the project's working directory exactly as described in references/folder-structure.md before any step runs.

Schema and endpoint references

• references/folder-structure.md — canonical project layout
• references/shot-list-spec.md — the structured JSON schema Gemini outputs and your rewriter consumes
• references/seedance-prompt-rules.md — load-bearing rules for the Seedance prompt (CUT. SHOT N: syntax, why narrative beats fail)
• references/product-image-rules.md — what makes a Seedance-friendly product image (white seamless, studio lighting, text-on-product caveat)
• references/scrapecreators-social.md — Meta / TikTok / Instagram media-fetch endpoints
• references/gemini-video-analysis.md — Files API + generateContent for shot-list extraction
• references/wavespeed-nano-banana-2.md — text-to-image for the product hero (default — product-only)
• references/wavespeed-gpt-image-2.md — text-to-image alternative when the start frame has a person or label typography that must read
• references/wavespeed-seedance-2.md — image-to-video for the final clip
• references/verification-loop.md — clone-vs-reference shot-density check

Style guardrails

• One Seedance call per ad. No ffmpeg stitching, no separate voice generation. Native audio handles dialogue from the prompt text.
• Resolution default is 480p, NOT 720p. 720p reveals AI tells on mobile. 480p reads as authentic UGC.
• Aspect ratio is 9:16 for vertical-feed surfaces (TikTok / Reels / Shorts). Use 1:1 or 16:9 only when the user explicitly asks for it.
• The Seedance prompt is the single most failure-prone artifact. Read references/seedance-prompt-rules.md carefully — the wrong prompt structure produces a flat single-take video instead of a 4–5-cut multi-shot ad.
• The product image is the second most failure-prone artifact. Read references/product-image-rules.md — Seedance needs a clean white-seamless hero shot with no fine typography on the product.

Cost and time expectations

• Gemini video analysis: ~$0.01 per 15s reference, ~30–60s
• Nano Banana 2 product image: ~$0.04, ~30–90s
• Seedance 2.0 (15s, 480p, 9:16): ~$0.50, ~5–10 min
• One full clone end-to-end: ~$0.55, ~10–15 min wall time

Budget for 1–2 regeneration loops on Seedance if the first clone is flat — the verification loop catches this and tells you whether to regenerate.
