Countryside Duo
PromptEdit @video1 using these separate reference mappings. The dancer in the blue jersey, initially on the left: curly-haired woman in a red jacket from @image1. The dancer in the striped green/yellow jersey and cap, initially on the right: brown-haired man in a dark green sweatshirt and gray trousers from @image2. Move the scene to a quiet countryside village street with white cottages and a stone wall. Keep the motorcycle in its original position. Preserve the source movement, timing, camera path, framing, contact points and occlusion order. Track each subject through crossings and cuts; never merge identities or add people. Keep unlisted people and objects unchanged.
Original clips and effect examples from Higgsfield, shown as references. Generation uses the original and your photo; results may vary.
Independent workspace; not affiliated with Kling or Kuaishou. Preview free; credits are reserved when you generate.
