TikTok's Parent Company ByteDance Unveils A New AI Tool Capable Of Making Lifelike Videos From A Photo, Meet OmniHuman-1
In a recently published research paper on arXiv, Bytedance announced the development of a new AI tool capable of working seamlessly with images of any aspect ratio.
Bytedance, the parent company of TikTok, recently unveiled a new AI tool capable of generating lifelike videos of people talking, playing instruments and more using a single photo. Known as, OmniHuman-1, ByteDance says the new tool “significantly outperforms existing methods, generating extremely realistic human videos based on weak signal inputs, especially audio.”
OmniHuman-1: What Do We Know
In a recently published research paper on arXiv, the company announced the development of a new AI tool capable of working seamlessly with images of any aspect ratio. Whether the input is a portrait, a half-body shot, or a full-body image, the tool can generate highly realistic and detailed results across a wide range of scenarios. This level of versatility marks a significant advancement compared to existing AI models, many of which are limited to modifying facial expressions or generating simple lip-syncing effects to make static images appear as though they are speaking.

According to details shared on the OmniHuman-1 page hosted on Beehiiv, the research team showcased several sample videos demonstrating the tool's impressive capabilities. These examples featured dynamic hand gestures, full-body movements captured from multiple angles, and even animated sequences of animals in motion, highlighting the model’s adaptability and precision. One standout example is a black-and-white video where OmniHuman-1 animates the famous physicist Albert Einstein, making him appear as if he is delivering a lecture in front of a blackboard, complete with expressive hand gestures and nuanced facial expressions.
ByteDance, the company behind the tool, claims that OmniHuman-1 was trained using an extensive dataset comprising over 18,700 hours of human video footage. This training process involved diverse input types, including text prompts, audio clips, and physical pose data, allowing the model to accurately replicate natural human movements and expressions.
The researchers assert that OmniHuman-1 currently outperforms other similar AI systems across multiple performance benchmarks, setting a new standard for image-to-video generation technology. Although it’s not the first tool designed to convert static images into dynamic videos, ByteDance’s model appears to have an edge over its competitors, potentially due to the extensive training data sourced from platforms like TikTok, which provided a rich variety of human interactions and motion patterns for the AI to learn from.
