Portrait cinématographique de femme aux cheveux flottant dans le ciel

Create a realistic cinematic slow motion video from this image. Only the hair should move smoothly in natural slow motion, softly waving with gentle wind. The background (sky, clouds, light, environment) should also move slowly and subtly, creating a calm cinematic feel. Face, eyes, expression, body, clothes and jewelry must remain completely still like a frozen photo. No camera movement, no zoom, no shake. Ultra-realistic details, soft lighting, smooth slow motion, 4K quality, clean and stable output.
