Motion Capture (MoCap) in ACT 3 AI allows creators to record and apply real human movements to digital actors within their projects.   
The '''Motion Capture''' feature in [[ACT3AI|ACT 3 AI]] enables creators to animate [[Digital_Actors|Digital Actors]] using real human performance.   
By combining motion tracking with AI-driven animation, MoCap brings natural, lifelike performances to virtual productions without the need for costly studio setups.
By recording movement via webcam, smartphone, or professional mocap hardware, you can transfer natural body motions and facial expressions directly into your [[Scenes]] and [[Shots]].   
 
== Key Benefits ==
1. Capture authentic human movement for realistic character animation.
2. Integrate performances seamlessly into virtual sets and AI-generated environments.
3. Reduce animation time by replacing manual keyframing with live motion data.
4. Support for both high-end studio rigs and consumer-grade capture devices.
5. Align performances perfectly with scene blocking, camera movement, and dialogue.
 
== Motion Capture Workflow ==
1. **Select Your Capture Method** 
  Choose between:
  * **Full-Body MoCap:** Using professional suits (e.g., Xsens, Rokoko).
  * **Device-Based MoCap:** Using smartphones, webcams, or depth cameras.
  * **Facial Capture:** For lip-sync and expression animation.
 
2. **Connect MoCap Device to ACT 3 AI** 
  Use the platform’s MoCap integration tools to link your device or import motion files (FBX, BVH).
 
3. **Record the Performance**  
  Capture the actor’s movements, facial expressions, or gestures in real time.


4. **Apply Data to Digital Actors** 
This feature ensures that AI-generated characters retain realism, nuance, and emotional depth in your video projects.
  Assign the motion data to a [[Digital_Actor|Digital Actor]] in your scene.


5. **Adjust & Refine Animation**   
== Key Features ==
  Use AI smoothing and cleanup tools to remove jitter, fix foot sliding, or enhance subtle movements.
* '''Full-Body Mocap:''' Capture body movements such as walking, running, or gestures in real-time.
* '''Facial Capture:''' Sync lip movement and facial expressions with dialogue for lifelike performances. 
* '''Device Flexibility:''' Use a smartphone camera, webcam, or professional mocap suit. 
* '''Actor Mapping:''' Link captured motions to [[Digital_Actors|Digital Actors]] in the [[Asset library|Actor Library]]. 
* '''Preview in Editor:''' See real-time playback of captured motions in the [[Editor|Editor workspace]].  
* '''AI Smoothing:''' Automatically refine and clean motion data to reduce jitter or inconsistencies.


6. **Sync with Dialogue & Timing**  
== How to Use ==
  Match animations to pre-recorded or AI-generated voice lines.
# Open the [[Editor]] and select the '''Motion Capture Panel'''. 
# Choose the capture type (body, face, or hybrid). 
# Record a performance using a webcam, smartphone app, or connected mocap device.   
# Assign the motion data to a [[Digital_Actor|Digital Actor]]. 
# Preview the results in the [[Timeline]] or [[Top_Down_View|Top Down View]]. 
# Adjust with AI smoothing or re-record as needed.


7. **Preview in Virtual Set**  
== Applications ==
  Review the motion in context with the environment, lighting, and camera paths.
* Animate [[Characters|characters]] with realistic movement.
* Add facial emotion to dialogue scenes. 
* Capture group performances for crowd or ensemble shots.  
* Prototype action sequences with quick body captures before refining animations.


8. **Finalize & Save**  
== Tips ==
  Store the motion capture data for reuse in future scenes or projects.
* Ensure good lighting and contrast for best motion tracking.
* Use clear backgrounds to minimize capture errors. 
* Record multiple takes for complex sequences.  
* Combine with [[Asset library]] for fully synced performances.


== Supported Formats & Devices ==
== See Also ==
1. **File Formats:** FBX, BVH, CSV motion data.
* [[Digital_Actors|Digital Actors]] 
2. **Devices:** Xsens, Rokoko Smartsuit, Perception Neuron, iPhone TrueDepth, Kinect, webcam-based trackers.
* [[Characters]] 
3. **Integration:** Compatible with Blender, Unreal Engine, and Unity exports.
* [[Actor_library|Actor Library]] 
* [[Editor]] 
* [[Timeline]] 
* [[Top_Down_View|Top Down View]] 


== Best Practices ==
1. Record in a well-lit environment with minimal background movement.
2. Calibrate devices before each session for accuracy.
3. Use reference props (e.g., chairs, tables) to align physical performance with virtual set elements.
4. Keep movement loops short for easier editing and reuse.

Overview

The Motion Capture feature in ACT 3 AI enables creators to animate Digital Actors using real human performance. By recording movement via webcam, smartphone, or professional mocap hardware, you can transfer natural body motions and facial expressions directly into your Scenes and Shots.

This feature ensures that AI-generated characters retain realism, nuance, and emotional depth in your video projects.

Key Features

  • Full-Body Mocap: Capture body movements such as walking, running, or gestures in real-time.
  • Facial Capture: Sync lip movement and facial expressions with dialogue for lifelike performances.
  • Device Flexibility: Use a smartphone camera, webcam, or professional mocap suit.
  • Actor Mapping: Link captured motions to Digital Actors in the Actor Library.
  • Preview in Editor: See real-time playback of captured motions in the Editor workspace.
  • AI Smoothing: Automatically refine and clean motion data to reduce jitter or inconsistencies.

How to Use

  1. Open the Editor and select the Motion Capture Panel.
  2. Choose the capture type (body, face, or hybrid).
  3. Record a performance using a webcam, smartphone app, or connected mocap device.
  4. Assign the motion data to a Digital Actor.
  5. Preview the results in the Timeline or Top Down View.
  6. Adjust with AI smoothing or re-record as needed.

Applications

  • Animate characters with realistic movement.
  • Add facial emotion to dialogue scenes.
