TriCaster NDI via OBS Setup

Route ScoreBird overlays from OBS to TriCaster as an NDI source. This method lets you use OBS as a compositor and send a clean keyed overlay feed to TriCaster over your local network.

Requirements

OBS Studio installed
TriCaster on the same local network as the OBS computer
Your overlay URL from the ScoreBird Portal

Step 1: Install the OBS NDI Plugin

Download the OBS NDI Plugin from github.com/Palakis/obs-ndi/releases and run the installer.

A full computer reboot is required after installation before OBS will detect the plugin.

Run the NDI Plugin installer

Step 2: Enable NDI Output in OBS

After rebooting, reopen OBS. Go to Tools > NDI Output Settings, enable "Main Output", and give the stream a name. Click OK.

Tools > NDI Output Settings — enable Main Output

Step 3: Add ScoreBird as a Browser Source

Add a new Browser Source in OBS and configure it as follows:

URL format:

https://widget.scorebird.com/school/broadcast-overlay-v2?serial=[YOUR_SERIAL]&green_screen=true

Replace [YOUR_SERIAL] with your NeST serial number. The green_screen=true parameter sets the background to green for chroma keying.

Dimensions: Set width to 1500px and height to 85px.

Add Browser Source in OBS

Enter the overlay URL with green_screen=true parameter

Set dimensions to 1500×85px

Next, apply a Chroma Key filter to the browser source. Right-click the source, select Filters, add a Chroma Key filter, and set the key color to green.

Step 4: Configure TriCaster to Receive the NDI Stream

In TriCaster, add the OBS NDI output as a network source. Select the named NDI stream you configured in Step 2. The ScoreBird overlay will appear as a keyed input ready to use in your TriCaster production.

Troubleshooting

NDI output not visible in TriCaster? Confirm OBS is running with NDI Output enabled and both machines are on the same local network.
Plugin not appearing in OBS Tools menu? Reboot the computer — reboot is mandatory after NDI plugin installation.
Green background still showing? Verify the Chroma Key filter is applied to the browser source and the key color is set to green.
Score not updating? Ensure a game is active in your ScoreBird schedule and your NeST device is online.
