A brief to adapt
Start with 4 s at 720P. This is a writing example, not a tested output.
A baker places a loaf on a wooden counter and brushes flour from one hand. A slow push-in ends on the crust. Soft window light, a light tap on wood and quiet shop ambience.
Animate your own image
Upload your starting image in Image to video. Copying a prompt does not upload images or submit a task.
Keep the subject and setting from the starting image. Add a small, natural movement, while the camera slowly moves closer. Preserve the lighting and composition. End with a steady hold.
