Generate metaphor-based product video ads Veo 3
Go to Workflow

Description
How it works
1. Brainstorm metaphors – Takes product details (name, description, audience, value props) and generates 5 visual metaphors using Gemini 2.5 Pro
2. Select best metaphor – Scores each metaphor on relevance, AI efficiency, simplicity, abstraction, and visual appeal, then picks the winner and creates a 3-act script + short title
3. Generate main video prompt – Translates the winning metaphor and script into a 120–150 word cinematic Veo 3 prompt with lighting, camera movement, and atmospheric details
4. Generate complementary scene – Creates a 40–60 word prompt for a static background plate that visually matches the main scene
5. Create both videos – Generates two 8-second AI videos with Veo 3.0 and uploads both to GCS
6. Merge & render – Combines the main video, complementary background, product name, and metaphor title using Creatomate
7. Deliver – Sends the final ad to Telegram
