AI-Driven Live-Action Video Generator

I need a robust AI system that can automatically turn a short brief or script into polished, live-action marketing videos aimed at everyday consumers. The platform should ingest text, images, or simple prompts and return a finished clip that feels authentic, product-focused, and ready for social channels or ads.

Core workflow I’m picturing:
• User drops in a prompt, selects duration, aspect ratio, and a loose visual theme.
• Your engine sources or synthesises the live-action footage, handles voice-over (realistic TTS), background music, basic motion graphics, and brand colours.
• An editor-style interface then lets me tweak scenes, swap shots, or update on-screen text before rendering the final file in HD and mobile-ready formats.

Essential capabilities
• Live-action composition, not just animation.
• Consumer-oriented storytelling – upbeat pacing, clear call-to-action, product or lifestyle focus.
• Cloud-based processing so videos render quickly without local installs.
• Simple reuse: once a template works, I should be able to duplicate and refresh it for new campaigns in minutes.

Deliverables
1. Functional web app (or desktop tool) with a clean UI.
2. Documentation covering setup, model training or API keys, plus user guide.
3. One sample campaign: a 30-second consumer-facing spot produced entirely through the system.

Acceptance criteria
• Input-to-output time under ten minutes for a 30-second HD video.
• Footage must look genuinely live-action (stock or generated) and remain rights-safe.
• All branding elements editable via the interface—no code changes required.

If you’ve already worked with generative video, stock APIs, Stable Diffusion, D-ID, Runway or similar, this should feel familiar. Show me a quick demo or link to past AI-video work so I can see fluency with live-action generation. I’m eager to move fast once I find the right partner.
