Hallo is a powerful AI video generation tool that can generate singing and talking videos from a single image and audio input, and finely control the characters' expressions and postures. This technology is based on an advanced diffusion model, which significantly improves the synchronization accuracy between voice input and generated animation, achieving accurate matching of mouth shapes, expressions and postures. Hallo provides animation generation for virtual characters and real characters, supports a variety of motion controls, and can generate animations personalized according to different identities, and can even generate high-quality singing animations. It has broad application prospects and is expected to play an important role in entertainment, education, virtual assistants and other fields.
Main functions:
Virtual character animation generation: Generate realistic and dynamic virtual character animation through voice audio input, and achieve precise synchronization of mouth shapes, expressions and postures.
Real character animation generation: Apply this technology to real characters, and the generated animation can accurately reflect the expressions and movement changes of real characters.
Multiple motion control: Provides precise control of character expressions, postures and lip movements, and supports adaptive control of multiple expressions and postures to enhance the diversity and authenticity of animations.
Cross-actor application: Supports personalized animation generation for different identities, and generates animation effects adapted to different character identities through audio input.
Singing animation generation: Generate synchronous singing animation through voice and song audio input. The animation can accurately reflect the changes in mouth shape and expression during singing.
This technology generates animations of character lip synchronization, expression changes, and posture changes by inputting speech, improving the alignment accuracy between speech and generated animation, and making the lips, expressions, and postures of the animation more closely match the speech. The advanced technology and structure adopted enhance the real-time performance and visual effects of animation generation, making the generated animation more realistic and natural.
The results of this research are not only academically innovative, but also show great potential in practical applications, such as applications in entertainment, education, virtual assistants and other multimedia fields. Through this technology, users can interact with virtual characters more intuitively and vividly, and enjoy a richer and more realistic experience.
