"text": "An elderly East Asian man with sleek silver-white hair tucked behind his ears and a calm, dignified face dances with lively rhythm in a bright, sunlit dance studio with tall steel-framed windows and a pale maple floor. He wears an avant-garde color-blocked outfit: an open cobalt-blue and emerald-green wool jacket over a saffron-yellow silk mock-neck tunic, vivid magenta tailored straight-leg trousers with crisp creases and polished oxblood-red leather shoes. The jacket swings open as he turns, the trousers fold naturally at the knees and his shoes squeak lightly on the floor. Soft morning daylight falls through the windows, casting long shadows on the boards. Realistic skin texture, natural fabric movement, consistent clothing and identity throughout, steady lighting, sharp detail and smooth, natural motion."

"text": "An elderly East Asian man with sleek silver-white hair tucked behind his ears and a calm, dignified face dances with lively rhythm in a bright, sunlit dance studio with tall steel-framed windows and a pale maple floor. He wears an avant-garde color-blocked outfit: an open cobalt-blue and emerald-green wool jacket over a saffron-yellow silk mock-neck tunic, vivid magenta tailored straight-leg trousers with crisp creases and polished oxblood-red leather shoes. The jacket swings open as he turns, the trousers fold naturally at the knees and his shoes squeak lightly on the floor. Soft morning daylight falls through the windows, casting long shadows on the boards. Realistic skin texture, natural fabric movement, consistent clothing and identity throughout, steady lighting, sharp detail and smooth, natural motion."

About this workflow
Upload 1 reference character image and 1 driving video. Generate an animated video of the character matching the driving video's motion. Ideal for character animation, in-video character replacement, and motion transfer projects.
