# Create and Calibrate Actor

Because every person has a different body structure—including height, limb length, and joint placement—even the same movements can result in different motion capture outputs. In MOVIN Studio, an **Actor** refers to the person performing the motion. Each actor’s physical characteristics are extracted and stored through a calibration process, allowing MOVIN Studio to personalize motion tracking for that individual.

In the past, calibration often took a significant amount of time. However, MOVIN Studio completes calibration in just 3 seconds, thanks to the power of AI. Let’s walk through how to create an actor based on your unique body data.

## Clothing Guidelines for Mocap Actors

To achieve higher motion capture accuracy, the Mocap Actor’s hairstyle and clothing are very important.

* Hairstyle and Headwear
  * Loose or flowing hair can cause tracking errors during movement. For long hair, avoid styles like ponytails that swing during motion. Instead, tie the hair <mark style="background-color:$primary;">**securely in a bun**</mark>.
  * If headwear is required, we recommend options like <mark style="background-color:$primary;">**beanies or caps with short brims**</mark> that do not interfere with facial tracking.
* Clothing
  * We recommend wearing <mark style="background-color:$primary;">**slim-fit clothing**</mark> rather than loose or baggy outfits.
    * <mark style="background-color:$primary;">**Tight-fitting sportswear**</mark> such as compression wear, muscle-fit clothing, or leggings is ideal.
  * Clothing that does not flap or move excessively during dynamic motion is best.
    * Please avoid garments with loose elements such as lace, as well as accessories that may move during capture.
  * Do not wear reflective materials, including reflective clothing or shoes.
  * Make sure the boundary between pants and shoes is clearly visible.
    * If the hem of the pants covers the shoes, the distinction between the legs and feet may be lost, which can cause motion flipping (where the character’s front and back are inverted).

## Create Actor

* Whenever the performer changes, click 'Calibrate Actor' to generate a new profile.
  * If you skip this step and continue using a previous actor, motion data may degrade due to mismatches in joint locations and body proportions.&#x20;
* After creating a new actor, follow the same [#a-pose-calibration](#a-pose-calibration "mention") process.
* If the actor already exists, simply double-click the existing actor from the 'Actor' list.

## A-Pose Calibration

* Step into the center of the mocap zone, and hold an A-pose (arms angled down at about 45°) for 3 seconds without moving.
  * If you move during calibration or fail to maintain the pose, it may affect the quality of your captured data. Be sure to remain still in the A-pose for the full 3 seconds.
* If calibration fails or feels inaccurate:
  * Click [#create-actor](#create-actor "mention") to start calibration with a new actor,
  * Then, click [#delete-actor](#delete-actor "mention") to delete the old actor.

## Rename Actor

* To avoid confusion, we recommend renaming each actor to match the performer’s real name. This helps identify which actor profile was used for each recording.
* To rename, right-click the actor from the 'Actor' list, click the 'Rename' button and enter the desired name.

## Delete Actor

<figure><img src="/files/Tp262ofjL2rlgJcDBMUE" alt=""><figcaption></figcaption></figure>

* You can delete actors that are no longer needed or were incorrectly calibrated.
* To delete, right-click the actor from the 'Actor' list and click the 'Delete' button.
  * If you want to delete multiple actors at once, hold down the Ctrl key and click all the actors you want to delete. Then, right-click and click the 'Delete' button to remove all the selected actors.
* If only one actor remains, deletion is disabled. In this case, create a new actor using [#create-actor](#create-actor "mention"), then delete the previous one.
* The calibrated 'Actor' data persists even after quitting the app or shutting down the device, unless you delete it manually.

## Adjust Offset

* You can adjust the calibrated actor’s offsets to correct tilted or bent body parts. To do this, click the "Adjust Offset" button.
* There are four adjustable actor offsets available:
  * Leg Stretch: Higher offset values will straighten more heavily bent knees.
  * Leg Tilt: Higher offset values will correct legs that are leaning forward, bringing them to a more upright position.
  * Torso Tilt: Higher offset values will correct a backward-leaning torso, aligning it to an upright posture.
  * Head Tilt: Higher offset values will correct a head tilted upward, adjusting it to face forward.
