Description
How it works
1. Generate the script – Takes a "what if" question and creates a 24-second video script with 4 scenes (Hook, Wonder, Reality, CTA) using Gemini 2.5 Pro
2. Create Veo prompts – Translates each scene's visual description into a production-ready prompt (120–150 words) optimized for Google Veo 3.0
3. Generate voiceover – Converts each scene's script into natural speech using Google Text-to-Speech and uploads to GCS
4. Generate video clips – Creates four 8-second AI-generated video clips with Veo 3.0 and uploads each to GCS
5. Merge & render – Combines all video clips and audio tracks using Creatomate into a single 24-second video
6. Deliver – Sends the final video back via Telegram
