Clone ad — Seedance 2.0

Clone an existing video ad for a different product or offer. The agent analyzes the source video frame-by-frame, transcribes dialogue, extracts the visual style and beat structure, then generates a new Seedance 2.0 video adapted for the user's product.

How this differs from analyze-video:

• analyze-video → output is a reusable markdown template saved to prompt-library/
• clone-ad → output is a generated Seedance 2.0 video delivered to the user
