# Motion Capture

After successful calibration, you are ready to begin the motion capture process in Moverse Studio. The system currently supports capturing for **up to two persons**, and each actor must be initialized **one after the other**. Below are the steps to follow.

***

## Actor 1: Initialization and Capture

### Step 1: Actor 1 Enters Capturing Space

* Have the first actor enter the designated capturing space.

</Frame>

### Step 2: Start Capture

* Press the **Body Calibration** button  <Icon icon="person-walking" size={24} />.
* The user's body will instantly appear in the 3D viewer.
* After the 3D body becomes visible, the actor must walk lightly inside the capturing space for 3-4 seconds.

</Frame>

### Step 3: Stabilize Capture with a Static Pose

* Have the actor hold a static pose (e.g., an A-pose) to stabilize tracking.

</Frame>

* Press the **Motion Tracking** button to lock tracking.

<Warning>
  If you notice an extended time period with FPS drops after this step, the body calibration process must be repeated (Step 2).
</Warning>

### Step 4: Continuous Capturing

* The system is now ready to record full-body motion.

</Frame>

## (Optional) Actor 2: Add a Second Actor

If your project involves a second person, press "+" button and follow these extra steps **after initializing Actor 1**:

</Frame>

### Step 5: Actor 2 Enters Capturing Space

* Invite the second actor into the capturing space. The first actor stays on the side.

</Frame>

### Step 6: Start Capture for Actor 2

* Press the **Body Calibration** button again.
* A second body will now appear in the 3D viewer.
* After the second body becomes visible, the actor must walk lightly inside the capturing space for 3-4 seconds.

<Frame caption="A second body appears in the 3D viewer.">

</Frame>

### Step 7: Stabilize Actor 2 with Static Pose

* Have Actor 2 stand in a static pose.
* Press the **Motion Tracking** button again to initialize tracking for the second actor.

<Frame caption="The second actor stands in a static pose (e.g. A-pose).">
  <img src="https://mintcdn.com/moverse/gv9c9A_q_CHGl067/images/studio/second_alpha.png?fit=max&auto=format&n=gv9c9A_q_CHGl067&q=85&s=931f7f285b6ce13a2742867f8dea9139" width="1920" height="1032" data-path="images/studio/second_alpha.png" />
</Frame>

<Warning>
  If you notice an extended time period with FPS drops after this step, the body calibration process must be repeated (Step 6).
</Warning>

### Step 8: Both Actors Ready for Capture

* With both actors stabilized, you can now capture dual-person motion simultaneously in the same space.

</Frame>

### Step 9: Enable Hand Tracking and Finger Re-processing

* **Activate Hand Tracking**:   <Icon icon="hand" size={24} /> adds real-time hand tracking to the capture.
* **Cloud Re-Processing**: Enabling hand tracking also triggers finger re-processing in the cloud for greater fidelity.

***

### Step 10: Re-Capturing or Switching Actors

* To reinitialize tracking or switch actors:
  * Disable **Motion Tracking**.
  * Have the new actor enter and assume a static pose.
  * Re-enable **Motion Tracking** to restart tracking for the new session.

***

## Conclusion

The process for capturing one or two actors is nearly identical—initialize one actor at a time following the same steps. This sequential setup ensures precise calibration and tracking for both individuals. For questions or assistance, consult the troubleshooting guide or reach out to support.
