What makes a video prompt hold together
1. One shot, one camera move
Short clips break when a prompt asks for too much. Describe a single shot and a single camera move — a slow push-in, an orbit, a handheld follow — and say how long it lasts. Cuts and second scenes are better generated as separate clips.
2. Describe motion, not only the scene
An image prompt describes what is there; a video prompt also says what changes. Hair moving in the wind, steam rising, a car passing behind the subject: concrete motion gives the model something to animate and keeps the subject stable.
3. Start from a still you like
Most video tools accept a first frame. Generating that frame with an image prompt first, then animating it, gives you far more control over composition and light than describing everything in one video prompt.
