Full Body Sync

The Full Body Sync model animates a static image to mimic the face, lip, and body movements from a reference video, creating realistic, coherent motion through a video-to-image transformation process. High quality results begin with selecting a strong reference video. Following the best practices below will help you capture footage that produces stable, expressive, and visually appealing animations.

Reference Video Requirements

The quality of your reference video is critical. To achieve the best results, ensure your video settings and content align with the following specifications.

Recommended More Settings

Settings	Recommended	Description
Motion Intensity	0.39	Body motion filter that controls how many motion signals are applied. Range [0.3–1.0].
Motion Clarity	2	Controls motion clarity by adjusting the number of strong motion signals. Range [2–6].
Target Frame Rate	Default 24 fps	Controls overall motion smoothness. Higher frame rates result in smoother motion. If the reference video is less than or equal to 10 seconds, use default 24 fps If the reference video is greater than 10 seconds, use 20–15 fps

Recommended Frame Rate

For reference videos longer than 10 seconds, adjusting the frame rate helps prevent output duration from being shortened.

Video Length	Recommended Frame Rate	Description
Less than or equal to 10 seconds	24 fps	Keeps the default frame rate to ensure the output duration is not compressed and motion remains smooth.
Greater than 10 seconds	20–15 fps	Reduces frame rate to avoid instability and facial distortion. Recommended not to go below 15 fps.

Frame Rate Examples

Each example below uses the following reference video.

Frame Rate	Video Effect	Description
30 fps		Setting a too-high frame rate can significantly shorten the output duration.
24 fps		For reference videos under 10 seconds, 24 fps is recommended to ensure full effect and smooth motion.
15 fps		For reference videos over 10 seconds, 15–20 fps is recommended based on the video length. Motion may be slightly choppy, but video duration will be preserved.
10 fps		Setting the frame rate too low can cause stiff movements, facial distortion, and blurriness, affecting output quality.

Video Content Guidelines

Follow these guidelines to ensure the subject, motion, and framing of your reference video produce accurate and visually consistent results.

Clear Subject

The main subject should remain unobstructed and not noticeably blurry, so motion features can be accurately recognized.

Motion Range

Movements should be smooth and stable. Avoid prolonged side-facing poses or overly exaggerated actions such as somersaults or pole dancing. Half-body dance videos typically produce better motion transfer results than full-body dance videos.

Pose Posture

Choose upright standing poses and avoid high-difficulty movements such as sitting or squatting.

First-Frame Requirements

Make sure the first frame shows the full person and contains complete visual information with no missing parts.

Subject Requirements

Only single-person videos are supported. Avoid videos that include multiple people, animals, or other subjects.

Image Requirements

The image you provide plays a key role in generating accurate and consistent results. To ensure the model can correctly match your image to the reference video, make sure it meets the following compatibility guidelines.

Subject Compatibility

To achieve the best results, the pose and proportions in your image should closely align with those in the reference video:

• The initial pose in your image should match the starting pose in the video. For example, if the video begins with a standing pose, your image should also show a standing pose.
• The subject's proportions should be consistent between your image and the video. For example, if the video shows a full-body subject, your image should also be full-body.
