Hallo2
Overview :
Hallo2 is a facial animation technology based on a latent diffusion generative model, generating high-resolution, long-duration videos driven by audio. It expands upon Hallo's capabilities by incorporating several design improvements, including the generation of long videos, 4K resolution outputs, and enhanced expression control through textual prompts. Key advantages of Hallo2 include high-resolution output, long-duration stability, and enhanced control via textual prompts, making it significantly beneficial for generating diverse and rich portrait animation content.
Target Users :
Hallo2's target audience includes animators, video editors, game developers, and any professionals in need of generating or editing high-quality facial animations. It is particularly suited for applications where maintaining a stable and coherent character representation over an extended period is essential, such as in film post-production, virtual streaming, and online education.

How to Use
1. Visit the official Hallo2 website or GitHub page
2. Download and install the necessary software and dependencies
3. Prepare or select an audio file to drive the facial animation
4. Optionally, prepare textual prompts to enhance specific expression control
5. Run the Hallo2 model, inputting the audio file and textual prompts (if any)
6. The model will generate the corresponding facial animation video
7. Review the generated video to ensure that the animation quality and coherence meet expectations
8. If necessary, perform post-editing and adjustments on the generated video
