A practical image-to-video prompt formula
Write the subject’s action first, then the camera movement, then any small environmental motion that supports the shot. For example: “She turns towards the window. The camera slowly moves closer. The curtain moves gently in the breeze.” You do not need all three parts for every clip.
Runway’s official image-to-video guidance treats the input image as the source of composition and appearance and recommends focusing the text on motion. Google’s Veo guide also distinguishes subject action from camera movement. The examples here follow that approach; they are original starting prompts, not a claim of identical or tested results across models.
Begin with a clear image and a short, achievable action. If the prop is absent or the face is malformed in the source, repair the image first. Model support, available controls, and the length of the clip affect what a prompt can achieve.
