Advanced Ai Video Artist

I need a short commercial created entirely with generative-AI tools and techniques, yet indistinguishable from a live-action shoot. The final spot must look photorealistic, run 20–30 seconds, and be delivered in 4K (16:9) ProRes along with the project files so I can make future tweaks if needed...
