What you will get

A sharp subject, such as a cyclist, car or runner, against a background stretched into horizontal speed streaks, like a classic panning shot.

Why it works

A panning shot follows a moving subject so it stays sharp while the background streaks, and the prompt recreates exactly that effect. Naming the subject type, cyclist, car or runner, tells the model which way the motion goes. Horizontal speed streaks give direction. The last line protects the subject, colours and composition, which is the part an AI edit is most likely to change.

Common mistake

The subject blurs too.

Fix: Say the subject must stay crisp and detailed, with the motion only in the background and any spinning wheels.

Also watch for

The streaks go the wrong way. State the direction of travel, so the streaks run along it and behind the subject.
The blur is uniform. Ask for stronger streaks near the edges and gentler ones closer to the subject, to look like a real camera pan.

Try a variation: add dust and spray

Ask for a little dust or water spray kicked up behind the subject, in the same direction as the streaks.

Keep the subject sharp and add more space in front of it, with the speed streaks running horizontally behind.
