Using OBS Virtual Camera with LiveVoice

This guide explains how to use the OBS Virtual Camera to stream a Zoom or Microsoft Teams call into LiveVoice. By doing so, interpreters can use a single tool for interpreting. Additionally, the Loop-Trick can be used to integrate audio from Zoom or Teams into LiveVoice. For more details on the Loop-Trick, please see our dedicated Help Center article.

What Is OBS Virtual Camera?

OBS Virtual Camera is a feature within OBS Studio that allows you to output the video feed from OBS as a virtual webcam. This virtual webcam can then be selected in applications like Zoom, MS Teams, or LiveVoice, making it easier to manage a single video stream across multiple platforms.

Why Use OBS Virtual Camera with LiveVoice?

Using OBS Virtual Camera with LiveVoice has several benefits:

1. Streamlined Workflow: Interpreters only need to manage one tool (LiveVoice) to see the video and audio from MS Teams or Zoom.
2. Custom Layouts: OBS allows you to create professional layouts, overlay logos, or display multiple video sources.
3. Audio Integration: When paired with the Loop-Trick, both audio and video can be seamlessly transferred to LiveVoice.

Tips for a Smooth Experience

1. Optimize Layouts:
   • Use OBS Studio to adjust your layout, including cropping the video to focus on the speaker or adding overlays.
2. Test Before Going Live:
   • Always test your video and audio setup in both Zoom/MS Teams and LiveVoice to ensure everything is working as expected.
3. Manage Resources:
   • OBS can be resource-intensive. Close unnecessary programs to ensure smooth performance.
