Prompt

Image-to-video prompt: Preserve the retro, large-letter linen postcard aesthetic exactly. Do not add external elements or switch scenes. Animate the vintage 3D letters to playfully pop forward and backward in a wave-like motion. Inside the letter 'M', make the tiny riverboat chug along, puffing little clouds of white smoke. Inside the other letters, cause the magnolia blossoms to gently rotate, bringing the nostalgic scene to grand life.
