HunyuanVideo-Avatar
HunyuanVideo‑Avatar supports animating any input avatar images to high‑dynamic, emotion‑controllable videos using simple audio conditions. It is a multimodal diffusion transformer (MM‑DiT)‑based model capable of generating dynamic, emotion‑controllable, multi‑character dialogue videos. It accepts multi‑style avatar inputs, photorealistic, cartoon, 3D‑rendered, anthropomorphic, at arbitrary scales from portrait to full body. Provides a character image injection module that ensures strong character consistency while enabling dynamic motion; an Audio Emotion Module (AEM) that extracts emotional cues from a reference image to enable fine‑grained emotion control over generated video; and a Face‑Aware Audio Adapter (FAA) that isolates audio influence to specific face regions via latent‑level masking, supporting independent audio‑driven animation in multi‑character scenarios.

DreamActor-M1
DreamActor-M1 is a state-of-the-art diffusion transformer framework designed to generate realistic human animations from a single image. It offers fine-grained control over facial expressions and body movements, ensuring multi-scale adaptability from portraits to full-body views. It maintains temporal coherence in long videos, even for areas not visible in reference images. Its hybrid motion guidance combines implicit facial representations, 3D head spheres, and 3D body skeletons to achieve detailed animation control. Complementary appearance guidance uses multi-frame references to maintain consistency in unseen regions. A progressive three-stage training strategy optimizes different aspects of animation: starting with body skeletons and head spheres, adding facial representations, and finally fine-tuning all parameters.

AvatarFX
Character.AI has unveiled AvatarFX, an AI-powered video generation tool currently in closed beta. This technology enables users to animate static images into realistic, long-form videos featuring synchronized lip movements, gestures, and expressions. AvatarFX supports a variety of visual styles, including 2D animated characters, 3D cartoon figures, and non-human faces like pets. It maintains high temporal consistency in facial, hand, and body movements, even in extended videos, ensuring smooth and natural animations. Unlike traditional text-to-image generation methods, AvatarFX allows users to create videos directly from existing images, offering greater control over the final output. AvatarFX is particularly beneficial for enhancing AI chatbot interactions, enabling the creation of lifelike avatars that can speak, emote, and engage in dynamic conversations. Users interested in early access can apply through Character.AI's platform.
