ByteDance's latest portrait animation technology X-Portrait2 has brought an innovation to the animation production field with its ultra-low cost and high efficiency. This technology does not require complex motion capture, and only static portraits and performance-driven videos can be generated to generate lifelike animated videos, greatly simplifying the animation production process. Its core lies in the advanced expression encoder model, which can accurately capture and migrate subtle expression changes, and even complex expressions such as pouting and sticking out tongue can be perfectly presented, ensuring the high fidelity and expressiveness of the animation.
Recently, ByteDance launched the latest portrait animation technology X-Portrait2, aiming to create expressive and realistic character animations in an ultra-low cost and efficient way. Users only need to provide static portrait images and performance-driven videos, and X-Portrait2 can generate animated videos by transferring expressions in the video to portraits, thus simplifying the complex process of traditional motion capture and character animation.
The core of this technology lies in its advanced emoji encoder model, which has been trained on large-scale datasets and can implicitly encode tiny expressions in inputs. Combined with a powerful generative diffusion model, X-Portrait2 can generate smooth and expressive videos that transmit the actor's subtle facial expressions, even challenging expressions such as pouting, sticking out tongue, bulging cheeks and frowning. At the same time, the generated videos also maintain high fidelity in emotional performance.
When training the emoji encoder, the development team ensures a strong separation of appearance and movement, allowing the encoder to focus on the information related to the expression in the video. This design allows the model to achieve cross-style and cross-domain expression migration, and is suitable for a variety of scenes such as real storytelling, character animation, virtual agents and visual effects.
Compared with state-of-the-art methods such as X-Portrait and Runway Act-One, X-Portrait2 shows higher accuracy in fast head movements, tiny expression changes and personal emotional transmission for high-quality Animation content creation is crucial, such as animation content in animation and film production.
