Omnihuman

OmniHuman AI is your friendly gateway to creating stunningly realistic digital human videos. Imagine being able to take a simple photo of a person and bring it to life, making them talk, smile, and gesture naturally, all synced perfectly to your audio. That's exactly what OmniHuman does. It's a groundbreaking platform that uses advanced artificial intelligence to transform a single portrait image and an audio clip into a lifelike talking head video. The AI meticulously handles the complex task of lip-syncing and generating natural facial expressions and subtle head movements, making the result appear genuinely authentic. This tool is perfect for marketers, educators, business professionals, and content creators of all skill levels. Its core value is democratizing professional video production; it removes the traditional barriers of needing actors, expensive filming equipment, or complex animation software. With OmniHuman, you can generate personalized, engaging, and high-quality avatar videos in just minutes, enabling you to communicate your message more effectively and personally than ever before.

Perfect Lip Sync & Natural Expressions

At the heart of OmniHuman is its ability to create flawless synchronization between your audio and the avatar's mouth movements. The AI doesn't just move the lips; it analyzes the audio to generate a full range of natural facial expressions and subtle head movements. This attention to detail ensures your digital human doesn't look robotic but appears genuinely lifelike and engaging, capturing the nuances of real human speech.

Infinite-Length Generation

Unlike many video generators that are limited to short clips, OmniHuman is built for long-form content. Its advanced technology prevents error accumulation across video segments, allowing you to create videos of any length—from a short social media clip to an hour-long lecture or presentation—without any loss in video quality, lip-sync accuracy, or identity consistency.

Exceptional Identity Preservation

Your photo is your starting point, and OmniHuman ensures it stays recognizable. The platform excels at maintaining the original person's unique facial features, expressions, and character throughout the entire generated video. Whether you're using a photo of yourself, a colleague, or a brand ambassador, the final video will faithfully preserve their identity, making the content feel personal and trustworthy.

Simple Three-Step Workflow

OmniHuman is designed for simplicity. Creating a video is as easy as 1) uploading a clear portrait photo, 2) providing an audio file (by upload or using text-to-speech), and 3) clicking generate. The platform handles all the complex AI processing in the background, delivering a professional talking head video ready for download in just 100-300 seconds, with no technical expertise required.

Engaging Educational Content

Educators and trainers can create virtual instructors from a single photo. This allows for the production of consistent, high-quality lecture videos, tutorials, and online course materials at scale. A teacher's avatar can deliver infinite-length lessons with perfect lip-sync, making learning more personal and accessible for students anywhere, anytime.

Dynamic Marketing & Brand Campaigns

Marketing teams can produce personalized video content at speed. Create videos featuring a brand ambassador or CEO avatar for product announcements, social media campaigns, or personalized customer messages. This technology enables brands to maintain a consistent and engaging human presence across all channels without the logistical hassle of traditional video shoots.

Accessible Content Creation

OmniHuman can be used to enhance accessibility. For instance, organizations can generate videos featuring sign language interpreter avatars synchronized to audio, making content more inclusive. It also empowers individuals who are camera-shy or lack production resources to still create professional video content for YouTube, presentations, or internal communications.

Entertainment and Character Animation

Content creators, authors, and storytellers can bring characters to life. By animating illustrations, book characters, or original artwork, you can produce unique animated shorts, book trailers, or interactive story experiences. The natural expressions and lip-sync add a compelling layer of realism to fictional characters and narratives.

What kind of files can I upload to OmniHuman?

You can upload portrait photos in JPG, PNG, or WEBP format, with a maximum file size of 10MB. For audio, the platform accepts MP3, WAV, and M4A files. The current maximum audio duration for a single generation is 15 seconds, but the infinite-length feature allows you to create longer videos by processing in seamless segments.

How long does it take to generate a video?

The processing time for generating your digital human video is typically between 100 to 300 seconds. The exact time can vary based on server load and the length of your audio. Once processing is complete, you can immediately preview and download your video.

What is the quality of the output video?

OmniHuman generates videos in 720p resolution, providing clear and professional-quality output suitable for most digital platforms including social media, websites, and online learning management systems. The focus is on delivering high-fidelity lip-sync and natural movements within this standard definition.

Do I need any special skills or software to use OmniHuman?

Not at all! OmniHuman is built for everyone. You don't need any experience in animation, video editing, or AI technology. The entire process happens online through a simple web interface. Just follow the three-step upload-and-generate process, and the AI does all the complex work for you.
