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.

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.

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.

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.
