Provided by Fal — Learn More

Wan-2.1 is an advanced and powerful visual generation model developed by Tongyi Lab. It can generate videos based on text, images and other control signals. Wan-2.1 excels at generating realistic videos featuring extensive body movements, complex rotations, dynamic scene transitions, and fluid camera motions, and can accurately simulate real-world physics and realistic object interactions, while offering movie-like visuals with rich textures and a variety of stylized effects. It can also create text and dynamic text effects in videos directly from text prompts.

Guidance Scale
number
Higher guidance scales can help with preserving garment detail, but risks oversaturated colors.
default: 5•minimum: 1•maximum: 10
Shift
number
Shift controls how the model moves through the denoising process, affecting motion and time flow in your video. Lower values result in smoother, more predictable movement. Higher values result in more dynamic but sometimes chaotic motion.
