Inputs

prompttextarearequired

The prompt describing the final video to generate.

image_urlfilerequired

URL of the reference character image. The character in this image is animated (or used to replace a subject) according to the driving video.

video_urlfilerequired

URL of the driving (motion) video. The subject can be a human, multiple humans, or an animal.

modeselectdefault: "animation"

`animation` animates the reference character with the driving motion. `replacement` replaces the driving subject with the reference character while keeping the original scene.

Options: animation, replacement

driving_typeselectdefault: "end_to_end"

Driving signal for animation mode. `end_to_end` (default) drives directly from the SAM3-masked driving video and is the recommended, most robust path. `pose` renders an explicit NLF/DWPose skeleton from the driving video (more control for challenging inputs).

Options: end_to_end, pose

subject_typeselectdefault: "human"

Type of subject in the driving video. `animal` switches the SAM3 detection prompt to non-human subjects.

Options: human, animal

resolutionselectdefault: "512p"

Output resolution. 512p outputs 896x512 (landscape) or 512x896 (portrait); 704p outputs 1280x704 or 704x1280. Orientation is chosen automatically from the reference image aspect ratio.

Options: 512p

num_inference_stepsintegerdefault: 40

Number of diffusion sampling steps. Higher improves quality but is slower.

guidance_scalenumberdefault: 5

Classifier-free guidance scale. Controls prompt adherence versus creativity.

shiftnumberdefault: 3

Flow-matching noise schedule shift. 3.0 is recommended for the 512p tier.

seedinteger

Random seed. Leave empty for a random seed. The seed used is returned in the response.

enable_safety_checkerbooleandefault: true

Authorized callers may set false to request relaxed screening.
