Question: I need a motion capture solution that can track multiple people in a single video, do you know of any?

If you're looking for a motion capture system that can track multiple people in a single video, DeepMotion could be just the ticket. This web-based service uses AI-powered motion capture and real-time body tracking to generate 3D animations based on video input. It can track multiple people up to 8 in a scene, so it's good for digital creators, filmmakers and game developers. It's got a range of features, including face and hand tracking, physics simulation and different pricing levels, so it should be adaptable to different needs and workflows.

Another good option is Move AI, which offers markerless motion capture products using sophisticated AI, computer vision and biomechanics. It can capture single and multiple camera scenes and can handle up to 12 cameras, so it's good for a range of uses from game development to advertising campaigns. Move AI offers high-quality motion capture data and easy retargeting to common 3D animation software formats, so it should be adaptable to different industries.

For a more traditional AI-based motion capture tool, Plask Motion is worth a look. It can handle multi-person motion capture and offers real-time collaboration for multiple people. It's geared for game developers, filmmakers and virtual reality creators who need motion capture that's fast and realistic. Plask Motion can handle multiple file formats and can be used with software like Blender, Unreal Engine and iClone, so it should be accessible to a broad audience.
