How to Change Video Background without Green Screen

Today, I want to show you three different ways to modify or completely remove the background of your video. By following these methods, you can blur the background, replace it with an image, or even add a video background – all without using a green screen. These techniques utilize free apps and plugins.

The first method provides the best results but requires a high-end system. The second and third methods work on almost any PC but may not deliver the same quality. Let's dive into the details:

Method 1: Using OBS Studio and NVIDIA Broadcast

This method has high system requirements, but it provides the best results. Specifically, you need an NVIDIA RTX graphics card.

  1. Install OBS Studio:

    • Head to the OBS Studio website and download and install it for your operating system.

  2. Install NVIDIA Broadcast:

    • Confirm you have an NVIDIA RTX graphics card by clicking on "System Information" in your taskbar search and selecting "Display."
    • If "RTX" is included in the name, download NVIDIA Broadcast from the NVIDIA website.
    • Install and open NVIDIA Broadcast.
    • Select the camera and effect you want (e.g., blur, replace, or remove the background).

  3. Configure OBS:

    • In OBS, add a new Video Capture Device source.
    • Select the NVIDIA Broadcast device.
    • Add and position your media source (image, video, etc.) behind your video feed.
    • Record, stream, or create a virtual camera for platforms like Zoom or Microsoft Teams.

Method 2: Using an OBS Plugin for Background Removal

If you don’t have an RTX graphics card, you can use an OBS Studio plugin to create similar effects.

  1. Download the Plugin:

    • Visit the plugin download page and download the file for your OS.
    • Unzip and copy the contents to the OBS Studio directory (usually in C:\Program Files\obs-studio).

  2. Configure the Plugin in OBS:

    • Open OBS and add a new Video Capture Device source.
    • Click on the source, then click on "Filters."
    • Add a new "Audio/Video Filter" and select "Background Removal."
    • Configure the filter settings to your preference.
    • Add an "Effect Filter" and select "Chroma Key" to fine-tune background removal.

  3. Add and Position Media Source:

    • Add your media source and drag it to the bottom of the source list to position it behind the video.

Method 3: Using Snap Camera

Snap Camera offers an alternative approach with fun effects and simple green screen capabilities.

  1. Install Snap Camera:

  2. Configure OBS:

    • Add a new Video Capture Device source in OBS.
    • Select Snap Camera as the device.
    • Apply a "Chroma Key" effect filter to remove the green background.

  3. Add and Position Media Source:

    • Add your desired media behind the video, following the same steps as in the previous methods.

Working with Pre-Recorded Videos

You can apply these techniques to existing videos:

  • Import your pre-recorded video as a media source in OBS.
  • Apply the background removal filters.
  • Record the modified video.

These are the different ways to modify or remove a background in OBS Studio.
