Realistic Human Motion / Rotoscope Animator — Jump Rope Video

IMPORTANT: This is NOT a traditional cartoon, 2D explainer-video, or simple motion-graphics project. We need realistic human movement. We manufacture the Olympic Jump Rope, a segmented jump rope that has been used in American schools for decades. Our first assignment is a small paid test. We need a close-up shot showing only the lower legs and feet of one person completing approximately four realistic consecutive jumps with our segmented jump rope. The movement is critical. The rope must rotate naturally, pass correctly underneath the feet, strike the floor at the correct moment, and create the believable rhythm of someone actually jumping rope. We are open to rotoscoping, 3D animation, motion capture, AI-assisted video, video-to-video, compositing, or another technique that produces convincing human movement. We will provide photographs of the actual Olympic Jump Rope and visual references showing the look we want. When responding, please: Show us ONE example of your work that best demonstrates realistic human, sports, or athletic movement. Briefly explain how you would create our four-jump test. Estimate approximately how many hours you would need for the test. Please do not send general cartoon or explainer-video samples. If the paid test is successful, we have an immediate follow-up project: a short social-media video showing several very different people jumping rope, followed by additional video projects. We are hoping to find someone we can continue working with as these projects develop.
