Realistic AI Storytelling Video

I want to produce a short, realistic-looking video generated entirely with AI. The focus is on people and their activities and the final piece will be used purely for entertainment and narrative purposes.

Here’s what I already have:
• A rough storyline and visual references.
• Voice-over and music cleared for use.

What I need from you:
• Select and use the most suitable generative-video platform (Runway, Pika, Sora, or a comparable tool) to bring the story to life.
• Generate human-realistic characters and natural-looking environments that match the references I’ll supply.
• Handle prompt engineering, shot planning, and any AI enhancements necessary to maintain realism throughout.
• Deliver a finished 1080p (or higher) MP4 plus any project files/presets so I can iterate later if needed.

Acceptance criteria
1. Footage convincingly realistic—no obvious AI artifacts on faces, hands, or motion.
2. Narrative flow aligns with the provided script and timing cues.
3. Final export is color-graded, audio-synced, and ready to publish with no additional edits.

If you’ve already completed similar people-centric AI videos, please point me to your strongest example when you respond. I’m ready to get started right away and can provide the storyboard as soon as we agree on the approach.
