The fastest way to turn a photo into cinematic video with AI

There are dozens of ways to turn a still image into moving video with AI. Some are highly technical, some take hours, and plenty produce something you would never show a client. The workflow below is the one I keep coming back to: fast enough for real production, simple enough that anyone can follow it, and good enough to put in front of people who pay for the work.

It needs two tools, Runway and ChatGPT, and one photo you love. I'll walk you through it with the example I used myself: a Tesla Roadster in the desert.

Start with a photo you love

The image is your raw ingredient. Mine was the Roadster, but this works with any subject: a product, a person, a landscape.

Let Runway do the generating

Runway is the generator. It can turn a still into moving video, and it can also create new images based on your photo, like a close-up of the Roadster's wheel spinning through the sand. Runway's own getting-started guide covers the basics of image-to-video if you've never used it.

I think of Runway as the chef in the kitchen. It knows how to cook, but it needs a recipe.

Let ChatGPT write the recipe

This is where most people go wrong. They type a flat prompt straight into Runway, something like:

"Car driving in the desert."

That's like telling a chef to "make food". You'll get something, but it won't be refined. So I ask ChatGPT to write the recipe first. This is the kind of prompt it gives back:

"A drone drifts silently through a veil of desert mist at dawn. The Arizona landscape is barely visible, softened and obscured by the pale fog that clings to the red cliffs and cactus silhouettes. As the camera floats forward, the headlights of a Tesla slowly pierce through the haze, beams stretching and scattering in the mist. The drone holds a steady, ethereal glide, capturing a dreamlike moment where the desert feels otherworldly and vast. The mood is moody, mysterious, and cinematic — a balance of stillness and anticipation as the car emerges from the fog."

Instead of a generic request, you now have a cinematic blueprint that Runway can actually bring to life, with camera movement, light, atmosphere and mood. Runway's prompting guides make a related point: for image-to-video, the prompt should describe the motion rather than repeat what's already in the picture. My golden rule is simple. AI works best with AI, so let ChatGPT write the recipe before you hand it to Runway.

Generate, refine, upscale

Paste the cinematic prompt into Runway and hit Generate. Don't expect perfection on the first try. It usually takes a few rounds before it feels right, and each time I tweak the prompt in ChatGPT and feed the new version back into Runway.

Once you land on something you like, you can upscale it to 4K inside Runway. That's the moment an experiment stops being a concept and becomes something you can actually use.

Teach ChatGPT your style

If you want to go further, set up a small project in ChatGPT. Upload one file with instructions, so it always knows the structure you want, and another with examples of strong prompts you've written before. Over time it learns your style, and the quality stays consistent instead of depending on how awake you are that morning.

Where I use it

I use this workflow weekly in production work, mostly for mood boards, renders and client presentations. It's simple and affordable, and the tools are available to anyone.

If you want more control over camera moves, lighting setups and even multi-scene sequences, the next step is structured JSON prompts, where you define each element field by field. That's the Michelin-star kitchen, and a topic for another post. In the meantime, the rest of my daily kit is in The tools I use in 2026, and the bigger picture is in Why AI didn't kill creativity.

Don't overthink it

There are countless ways to make AI video. This one just happens to be the fastest and easiest I've found for turning a still into cinematic motion. Pick a photo, follow the steps, and start creating.

If you try it, whether it's a full car chase or a single wheel carving through the sand, send it my way. I'd love to see what you make. And if you're wondering how this could fit into your own production, you can see selected work or book a 1-1.
