Thousand-Face Video Motion Capture

What is facial tracking in video?

Qianmian Video Motion Capture is an AI motion capture tool without the need for markers, provided by Qianmian Zhiyu; it is often referred to simply as Qianmian Motion Capture.

It identifies human movements in ordinary videos and then generates motion data that can be used by 3D animation software.

Core functions

Video motion capture capability

The platform supports both fixed and moving camera footage, and can handle videos with 24, 30, 60, and 120 frames per second.

• Full-body capture: suitable for dance, performances, game characters, and virtual human movements.
• Half-body capture: Used for voiceovers, live streaming, or projects that require only upper-body movements.
• Hand capture: It detects changes in fingers and gestures, enhancing the details of movements.
• Facial capture: Replicates facial expression changes to assist in character performance production.
• Multi-person capture: It can handle footage featuring multiple people, but complex occlusions require quality verification first.

The export format is compatible with the software.

FaceSync can integrate with common 3D, game engine, and character animation workflows.

• Common formats: FBX, BVH, BIP, VMD, and C4D.
• Game engines: Unreal, Unity Anim, and Roblox.
• Character pipelines: Mixamo, CC&iClone, and Onlyface.
• Digital human video: The corresponding features are output in MP4 format.

The free version only provides FBX; other formats and commercial licensing require a paid plan.

Tutorial for using FaceSync video motion capture

1. Register and log in to Qianmian Zhiyu, and first determine the export format and permissions required for the project.
2. Prepare videos with complete characters, stable lighting, and minimal obstruction, while trying to reduce camera shaking as much as possible.
3. Upload the material and choose options for processing such as full body, half body, hands, face, or multiple people.
4. Set the pose for the first frame, choose between stationary or moving mode, and match it to the actual frame rate of the material.
5. First, generate a preview using a short video to check for foot slippage, mesh penetration, jitter, and joint orientation.
6. Use 2D restoration or recrop the material as needed, then submit the completed task.
7. Download in the target format, and perform the redirection in Blender, Maya, Unreal, or Unity.
8. Before delivering the project, verify the commercial usage rights and back up the original videos, animation files, and project files.

Suggestions for preparing materials

• The person should be shown as completely as possible within the frame, with their hands and feet not extending outside the image for long periods.
• The color of the clothing should differ slightly from that of the background, to prevent the outlines from being difficult to identify.
• Reduce intersections between characters, rapid occlusions, and severe motion blur.
• First, upload a 10 to 20-second test clip, and then decide whether to process the longer video material.
• A high frame rate will affect the processing time and the amount of resources consumed, so it is necessary to check this in advance.

Individual subscription price

The following are the individual plans displayed on the official website’s pricing page as of August 30, 2026; the annual payment amounts are shown as the equivalent monthly price.

The paid version includes a commercial license as well as more export formats, while the number of team seats in the studio version is determined by the actual availability of that version.

Prices, taxes, promotions, and benefits may change; the terms applicable are those stated on the purchase page, the checkout page, or the contract.

Limits and asset retention rules

• The monthly quota is intended for the features that are already available, such as motion capture, text-based motion capture, and digital avatars.
• The annual payment option requires a one-time payment, but the credit limit is still issued on a monthly basis; any unused credit limit is not carried over automatically.
• Different models, durations, frame rates, numbers of users, and processing methods may result in varying amounts of consumption.
• Assets remain intact during the valid period of the paid subscription; after the account is switched to the free version, they are retained for 15 days.
• After 15 days, it enters a 7-day deletion phase, after which the files cannot be restored.
• Important materials and action data should be downloaded and a local backup created before their expiration date.

API package prices

The API is designed for product integration, server-side calls, batch tasks, and high concurrency requirements; it is sold separately from individual subscriptions.

The studio version of the personal website does not include API call permissions; to integrate the program, it is necessary to purchase a separate API package.

Once the API quota expires, it cannot be extended, carried over, or converted into a personal subscription quota.

API and open-source status

• API: The official website offers separate packages, suitable for integration in platforms, studios, and enterprises.
• API Key: It should be stored on the server side and must not be included in the web interface or in public code repositories.
• SDK: As of the time of verification, no official SDK repository that can be confirmed was found.
• Open source: No complete source code for the platform, no weights for motion capture models, and no official open-source license available.

Providing an API does not mean that the product is open-source, nor does it imply that individuals who subscribe automatically gain access to those interfaces.

Which users are it suitable for

• Independent animators: Quickly create a preliminary version of the characters’ movements based on live-action performances.
• Game developer: Create prototype animations and import them into Unity or Unreal.
• MMD and virtual idol creators: generate formats such as VMD.
• Digital human team: handles action imitation, character replacement, and voice-over materials.
• Film, television, and short-video teams: lowering the barriers to action rehearsals and mass production.
• Developers and enterprises: Build automated motion capture processes using independent APIs.

Advantages and usage limitations

Main advantages

• No motion capture suits, markers, or specialized studios are needed; ordinary camera footage is sufficient to get started.
• It meets a variety of capture needs, including those for the body, hands, face, and multiple people.
• There are many export formats, which facilitate integration with major 3D software and game engines.
• It also offers both a personal web interface and a standalone API solution.

It is necessary to pay attention.

• Obstructions, blurring, elements that go outside the frame, and rapid camera movements can reduce the quality of the action.
• Automated results may still suffer from slippage, jittering, mesh penetration, or deviations in bone orientation.
• The free version has limitations regarding video length, file size, export format, and retention period.
• Before uploading videos featuring real people, permission for the use of their portraits, performances, and related materials must be obtained.
• When generating actions, it is still necessary to check for redirection and collisions on the target character’s skeleton.

Frequently Asked Questions

Does facial animation video capture require capture equipment?
