I have an MP4 clip that feels a little empty, and I’d like it to burst to life with 3 friends just being silly seamlessly composited into the scene. The goal is simple: once the edit is done, no one should be able to tell the dancers were ever missing. Here’s what I need from you: • Track the existing camera movement and lighting so the added performers fit naturally. • Match shadows, reflections, and color grade to preserve a consistent look throughout the sequence. • Supply any royalty-free or self-created motion-capture or green-screen footage you use, cleared for my ongoing use. • Deliver the final video in the same MP4 format, resolution, and frame rate as the source, plus a separate file (ProRes or lossless) if practical so I can archive the highest-quality render. If you already have a library of hip-hop, ballet, salsa, or other styles, feel free to recommend what works best with the footage; I’m open as long as the result looks authentic. Please let me know your preferred tools (After Effects, Blender, DaVinci Fusion, etc.) and how quickly you can turn the edit around.
