Virtual Background

Last updated: 2022-04-06 20:01:23

    Overview

    Background is an application of the portrait segmentation technology. During a video meeting, VooV Meeting can automatically recognize the attendees and replace their backgrounds with the specified image or video. On one hand, the virtual background can protect the attendees' privacy; on the other hand, it can replace a real exhibition background to facilitate themed promotion of the meeting and reduce the meeting costs. To get a better virtual background experience, we recommend you use this feature in a simple scenario with even lighting. If you have a green screen, you can use the green screen feature to further improve the virtual background effect.

    Notes

    Requirements for customized image or video:

    • Image:
      • Format: .jpg, .bmp, .png
      • Resolution: 4096 × 4096
      • Size: within 20 MB
      • Aspect ratio: 0.01–100. We recommend you use 16:9
      • Quantity: 19 images for Android/iOS each and 49 images for macOS/Windows each. The quantity includes the numbers of blurred backgrounds, images in the system, and images uploaded by users.

      • Size: unlimited

    To have a better virtual background experience, we recommend you use this feature in a simple environment:

    • If the environment has few objects and monotonous background color, we recommend you use green screen.
    • A clearer camera is used for the video meeting.
    • The lighting in the meeting environment is even.
    • Avoid dressing in the same color as the background.

    If video is used as the virtual background, do not block the camera:
    After the camera is blocked, the capture frame rate will become too low and reduce the refresh rate, which will slow down background loading.
