However, they might struggle with complicated fighting movements, because they often make mistakes in simulating the momentum, force, and timing that fighting movements occur in the real world.

In this guide, we will walk you through the best tools, tips and editing skills needed to create a vivid, realistic fight video with minimal hallucination. Whether you are looking to enhance your gaming streams, spice up your social media posts, or create cinematic pieces, keep reading and turn your vision into epic fight videos.

How AI Fight Generators Work

Similar to AI image generators, AI video generators begin by analyzing a large data set of motion capture data, 3D models, and video footage. They help AI understand how a fight should look. Whenever a user input the type of fight they want (e.g., martial arts, sword fighting), AI would synthesize these actions using pre-learned movements, and blend them together.

That’s not the end. Some AI generators use methods like Physics Simulation, Inverse Kinematics, Real-Time feedback to refine the output.
