Model overview
motion_diffusion_model is a diffusion model developed by Replicate creator daanelson for generating human motion video from text prompts. It is an implementation of the paper "Human Motion Diffusion Model" and is designed to produce realistic human motion animations based on natural language descriptions. The model can be used to create animations of people performing various actions and activities, such as walking, picking up objects, or interacting with the environment.
Similar models include stable-diffusion, a latent text-to-image diffusion model that can generate photorealistic images, stable-diffusion-animation, which can animate Stable Diffusion by interpolating between prompts, and animate-diff, which can animate personalized Stable Diffusion models without specific tuning. While these models focus on generating images and videos from text, motion_diffusion_model is specifically designed for generating human motion.
Model inputs and outputs
motion_diffusion_model takes a text prompt as input and generates a corresponding animation of human motion. The text prompt can describe various actions, activities, or scenes involving people, and the model will attempt to create a realistic animation depicting that motion.
Inputs
- Prompt: A natural language description of the desired human motion, such as "the person walked forward and is picking up his toolbox."
Outputs
- Animation: A video sequence of a 3D stick figure animation depicting the human motion described in the input prompt.
- SMPL parameters: The model also outputs the SMPL parameters (joint rotations, root translations, and vertex locations) for each frame of the animation, which can be used to render the motion as a 3D mesh.
Capabilities
motion_diffusion_model is capable of generating a wide variety of human motions based on text descriptions, including walking, running, picking up objects, and interacting with the environment. The model produces realistic-looking animations that capture the nuances of human movement, such as the timing and coordination of different body parts.
One key capability of the model is its ability to generate motion that is semantically consistent with the input prompt. For example, if the prompt describes a person picking up a toolbox, the generated animation will show the person bending down, grasping the toolbox, and lifting it up in a natural and believable way.
What can I use it for?
motion_diffusion_model can be used for a variety of applications that require generating realistic human motion, such as:
- Animation and visual effects: The model can be used to create animations for films, TV shows, or video games, where realistic human motion is important for creating immersive and believable scenes.
- Virtual reality and augmented reality: The model's ability to generate 3D human motion can be used to create interactive experiences in VR and AR applications, where users can interact with virtual characters and avatars.
- Robotics and human-machine interaction: The model's understanding of human motion can be used to improve the way robots and other autonomous systems interact with and understand human behavior.
Things to try
One interesting thing to try with motion_diffusion_model is to experiment with different types of prompts and see how the model responds. For example, you could try generating motion for more abstract or imaginative prompts, such as "a person dancing with a robot" or "a person performing acrobatic stunts in the air." This can help you understand the model's capabilities and limitations in terms of the types of motion it can generate.
Another interesting thing to try is to use the model's SMPL parameters to render the generated motion as a 3D mesh, rather than just a stick figure animation. This can allow you to create more visually compelling and realistic-looking animations that can be integrated into other applications or used for more advanced rendering and animation tasks.

This model builds upon existing work like Stable Video Diffusion and Lavie, which explore generating videos from text or images using diffusion models. The stable-diffusion-videos-mo-di model specifically uses the Mo-Di Diffusion Model to create smooth video transitions between different text prompts. Model inputs and outputs The stable-diffusion-videos-mo-di model takes in a set of text prompts and associated seeds, and generates a video by interpolating the latent space between the prompts. The user can specify the number of interpolation steps, as well as the guidance scale and number of inference steps to control the video generation process.
