Realistic AI Promotional Video Creation

I need a short, highly realistic promotional video generated with AI. The finished piece must look as if it were shot with a real camera, yet be created entirely through AI tools of your choice (e.g., Synthesia, Runway, Pika, Midjourney + AnimateDiff—whatever delivers the most lifelike result).

Core requirements
• Purpose: a concise promotional video for a product launch.
• Elements: incorporate on-screen text overlays and a clear, friendly voice-over narration. I already have the key marketing points; you can help refine them into a tight script.
• Tone: warm and approachable rather than corporate—think brand explainer that invites viewers in.
• Length: 45–60 seconds is ideal, as long as every second feels purposeful.

Deliverables
1. Final video file in 1080p (4K welcome if your workflow allows).
2. Separate audio stem of the narration.
3. Editable project file or prompt stack so I can update content later.

Acceptance criteria
– Visuals read as “real world” at first glance.
– Voice-over is fluent, friendly, and free of robotic artifacts.
– Text overlays are crisp, timed well with the narration, and use brand colours that I’ll supply.
– No copyright-restricted assets.

If you have past samples of AI-generated promo spots, please share a link so I can gauge realism and style. I’m ready to begin as soon as I find the right fit and can turn feedback quickly to keep momentum.
