## NDI Setup Guide

NDI allows you to send your screen wirelessly over your local network to the PC running SpectraAI.

### 1. Prerequisites

Before starting, ensure you have OBS Studio installed.

1. **Download OBS:** [Official OBS Website](https://obsproject.com/)
2. **Download DistroAV:** Visit the [DistroAV GitHub Releases](https://github.com/DistroAV/DistroAV/releases/tag/6.1.1) and download **`distroav-6.1.1-windows-x64-Installer.exe`**.

### 2. Installation

1. Install OBS Studio (if not already installed).
2. Run the **DistroAV Installer**.
3. Open OBS Studio.
4. **Important:** Upon opening OBS, you will be prompted to install **NDI Runtimes**.
   * Click the prompt to download the file.
   * Install the downloaded Runtimes.
   * **Restart OBS** for the changes to take effect.

### 3. OBS Video Configuration

You must configure the video output to match the AI's requirements.

1. Go to **Settings > Video**.
2. **Base (Canvas) Resolution:** Set to `640x640` or what shown in the table in Capture Methods
3. **Output (Scaled) Resolution:** Set to `640x640`.
4. **Common FPS Values:** Change this to **Fractional FPS Value**.
   * **Numerator:** `120` (Minimum)
   * **Denominator:** `1`
5. Click **Apply** and **OK**.

### 4. Scene Setup

1. In the **Scenes** box, create a new Scene.
2. In the **Sources** box, click `+` and select **Display Capture**.
3. Select your primary gaming monitor and click **OK**.
4. **Center the Source:** Press `CTRL` + `D` on your keyboard. This ensures the capture is perfectly centered.
5. **Lock Preview:** Right-click strictly on the video preview area and select **Lock Preview** (this prevents accidental movement).

### 5. Activate NDI Output

1. In the top menu bar, go to **Tools > Distro AV NDI**.
2. Check the box labeled **Main Output**.

Your screen is now broadcasting via NDI. You can now select "NDI" in the SpectraAI menu.
