AI Instagram Marketing Video

I need a short, professionally-toned AI-generated video that will run on Instagram as a marketing asset. The clip should feel sleek, modern and brand-aligned, sized for vertical 9:16 and optimized so it looks crisp in both the feed and Stories. You are free to combine generative tools such as Runway, Pika, Midjourney or similar for visuals, text-to-speech or voice-over, but the finished piece must feel cohesively edited rather than a string of AI snippets. If the story flow requires a brief script, include that step in your process; I’m happy to approve it before final rendering. Deliverables • 1– 20 second MP4 ready for direct Instagram upload • Hard-burned captions (or an .srt file) for silent autoplay • A single thumbnail frame that fits Instagram’s 1:1 grid We will provide shot frames and script Acceptance criteria • Professional look and pacing suitable for a marketing objective • All assets either licence-free or clearly documented as AI-generated • Final file under 30 MB without visible compression artifacts Please outline the AI tools you intend to use and your estimated turnaround time when you respond.
