Question: I need a platform that can help me create realistic animations with physics simulations and customizable characters.

If you're looking for a platform to create realistic animations with physics simulations and customizable characters, DeepMotion is a great option. This web-based tool uses AI-powered motion capture and real-time body tracking to let you create 3D animations from video input. It includes features like text-to-3D animation, customizable characters and advanced physics simulation, so it's good for digital creators, filmmakers and game developers.

Another interesting option is Motorica, which offers AI-powered motion capture for fast and efficient AAA animation. Motorica does away with the hassle of complex setup and post-processing so animators and content creators can create high-quality animations in minutes. That means it's a good option for those who want to optimize their animation pipeline and get professional results as quickly as possible.

For a more general-purpose option, Move AI offers markerless motion capture technology to convert 2D video into 3D motion data. It can handle single and multi-camera capture, hand and finger tracking, and high-quality motion data. Move AI is good for a variety of industries, including game development and commercial campaigns, and offers scalable pricing options to accommodate different needs.

If you want more control over keyframe animation, Cascadeur might be a good option. This standalone software is geared for humanoid or character animation with AI tools for fast pose creation, immediate physics results and automated rigging. It has features like animation unbaking and copy/paste retargeting, too, so it's a good option for 3D action animation pros.
