Enabling or Disabling Your VeloTwin Face Overlay** Open the **Face** panel from the right sidebar. At the top of the panel you will find the **Use VeloTwin** toggle. * Switch it **on** to display your VeloTwin face in the video. * Switch it **off** to remove the face overlay entirely without deleting your VeloTwin settings. Description ### **2. Changing Which VeloTwin Appears** When the face overlay is enabled, your currently selected VeloTwin is shown as a preview card: * You cannot change the face of VeloTwin, as you have already selected the voice of same twin. Description ### **3. Adjusting Camera Position** Use the **Camera Position** grid to snap your VeloTwin to a specific location on screen. The grid provides nine anchor points - corners, sides, and the center. * Click a circle on the grid to move your face overlay to that position. Description ### **4. Adjusting Camera Size** Use the **Camera Size** slider to scale your VeloTwin up or down. * Slide right to make the face overlay larger and more prominent. * Slide left to make it smaller and more discreet. Description ### **5. Changing the Shape of the Face Overlay** In the **Shape** section, choose from three preset frame styles: * **Original** - Your default captured frame shape. * **Square** - A perfectly even four-sided frame. * **Round** - A circular bubble look. Description ### **6. Shrinking Your VeloTwin During Zoom** When the video zooms in on your screen recording, your face overlay may cover the highlighted content. To prevent this: * Enable the **Make Smaller during zoom** toggle. * Use the **Size during Zoom** slider to set exactly how small the overlay becomes when a zoom block is active. * Click **Reset** to return to the default zoom behavior.
