Bringing Still Images to Life with AI-Powered Video Generation
OmniHuman is a cutting-edge AI model from ByteDance that transforms a single image and an audio track into a realistic, full-body animated video.
This powerful technology synchronizes natural speech, gestures, and movements to create lifelike digital humans, opening up a world of possibilities for creators across various fields. Whether you're looking to build digital avatars, produce engaging educational content, design compelling marketing presentations, or tell captivating stories, OmniHuman provides the tools to bring your vision to life.
The model is designed to work with a wide range of visual styles, from photorealistic portraits to artistic paintings and even cartoon characters. It preserves the unique aesthetic of your original image while adding fluid, natural animation. With support for multiple languages, OmniHuman is a versatile solution for creating multilingual content with a consistent visual identity.
How It Works
OmniHuman leverages a sophisticated deep learning framework trained on over 19,000 hours of video data. This extensive training enables the model to understand the complex relationships between speech, facial expressions, and body movements across different languages and cultural contexts. When you provide an image and an audio file, OmniHuman analyzes both inputs to generate a seamless and natural-looking animation.
The process begins with the model identifying key facial features and body landmarks in the input image. It then maps the audio's phonetic and emotional content to a corresponding set of facial expressions and body gestures. The result is a high-quality video where the animated subject speaks and moves in a way that is both convincing and true to the original image's style.
Key Features
OmniHuman is packed with advanced features that provide a high degree of control and flexibility in generating animated videos. These features are designed to ensure that the final output is not only realistic but also perfectly aligned with your creative vision.
Full-Body Animation
Unlike traditional lip-sync technologies that focus solely on mouth movements, OmniHuman generates comprehensive full-body animation. This includes coordinated gestures, subtle posture adjustments, and natural body language that complements the speech content. The model's understanding of human movement allows it to create animations that feel authentic and engaging.
Style Preservation
One of OmniHuman's standout features is its ability to preserve the artistic style of the input image. Whether you're working with a photorealistic photograph, a detailed illustration, or a stylized cartoon character, the model will maintain the original aesthetic while adding lifelike animation. This ensures that your animated content remains consistent with your brand or artistic direction.
Multi-Language Support
OmniHuman supports a wide range of languages, with automatic language detection and natural pronunciation. The model is trained on a diverse dataset of multilingual speech, enabling it to generate accurate lip-sync and appropriate cultural nuances in gestures and expressions. This makes it an ideal tool for creating content for a global audience.
Advanced Audio-Visual Synchronization
At the core of OmniHuman is a sophisticated audio-visual synchronization engine. This technology ensures that the animated subject's mouth movements, facial expressions, and emotional tone are perfectly aligned with the audio content. The result is a highly realistic and immersive viewing experience.
Getting Started with OmniHuman
Creating your first animated video with OmniHuman is a straightforward process. Follow these steps to bring your still images to life:
1. Input an Image
Begin by uploading a clear, well-lit image of your subject. For the best results, use a front-facing or slightly angled shot where the facial features are clearly visible. OmniHuman supports a variety of image types, including:
Photorealistic Photos: High-resolution headshots or portraits work exceptionally well.
Artistic Paintings and Illustrations: The model can animate a wide range of artistic styles.
Cartoon Characters: Bring your animated characters to life with natural speech and movement.
2. Input an Audio Track
Next, provide the audio content for your animation. You can either upload an audio file or use the built-in text-to-speech feature. OmniHuman's text-to-speech engine supports multiple languages and provides natural-sounding voices.
3. Generate and Review
Once you've configured your inputs and parameters, you're ready to generate your video. After the generation process is complete, you can preview the result and make any necessary adjustments to the audio or image to achieve the perfect animation.

Model Limitations
Technical Considerations - To achieve the best results with OmniHuman, it's important to keep the following technical considerations in mind:
Multiple Subjects
The model is optimized for single-subject images. If multiple faces are present in the input image, they may be unintentionally animated.
Non-Speech Audio
While OmniHuman can handle a wide range of speech, it is not designed for singing or other non-verbal sounds.
Complex Actions
The model focuses on speech-related movements and may not accurately animate complex physical activities.
Background Elements
In some cases, the model may inadvertently animate faces or objects in the background of the image.
Best Practices
To maximize the quality and effectiveness of your OmniHuman animations, consider the following best practices:
Image Selection
Choose High-Quality Images
Start with the highest resolution image available. Clear, well-lit photographs will always produce better results than low-quality or blurry images.
Focus on Facial Features
Ensure that the subject's eyes, nose, and mouth are clearly visible and well-defined in the image.
Consider the Background
Simple, uncluttered backgrounds work best. Avoid images with multiple faces or complex background elements that might interfere with the animation process.
Audio Preparation
Script Your Content
Plan your audio content in advance to ensure it matches the tone and style of your visual subject.
Use Clear Pronunciation
Speak clearly and at a moderate pace to help the model generate accurate lip-sync.
Match the Character
Consider the personality and background of your visual subject when writing and recording the audio content.
Workflow Optimization
Preview Before Finalizing
Always review your generated video before using it in your final project. This allows you to make adjustments if needed.
Iterate and Refine
Don't hesitate to experiment with different audio content or image adjustments to achieve the perfect result.
Consider Your Audience
Keep your target audience in mind when selecting images and crafting audio content to ensure maximum engagement.
