Workflow outlined in the video
- Structure detailed timeline prompts in Markdown format to describe shot-by-shot action sequences.
- Use Claude to reverse-engineer successful video prompts into structured templates.
- Generate high-quality input reference images using cost-effective models like Soul Cinema before running video generations.
- Optimize generation costs by testing and refining prompts in 720p or 1080p before committing to 4K renders.
- Prepare assets for Seedance 2.5 by organizing up to 50 distinct reference images and audio files for unified campaign generation.
