Whether you’re just starting out on Twitch, YouTube, Kick, or another platform, or you’re a seasoned creator looking to streamline your setup, integrating your Elgato Stream Deck with OBS Studio is a game-changer. Custom alerts – like the premium .WEBM files from PixelsLucky.com – add excitement without interrupting your flow. No more fumbling with hotkeys; just press a button to play animations seamlessly.

This guide walks you through the simplest method: using Stream Deck’s Media Source Control to trigger .WEBM alerts in OBS. It’s beginner-friendly (no coding required) yet powerful enough to save time for pros. Let’s get your alerts popping!

Why Use Elgato Stream Deck with OBS Alerts?

• For New Streamers: Turn complex OBS controls into one-tap buttons, making your streams look professional without tech headaches.
• For Experienced Streamers: Automate alerts for efficiency so you can focus on content. Plus, .WEBM alerts from PixelsLucky.com are lightweight, high-quality, and transparent for perfect overlays.

Step 1: Install the OBS Studio Plugin for Stream Deck

This connects your Elgato Stream Deck to OBS for remote control.

1. Open the Stream Deck app on your computer.
2. Click the colorful Marketplace icon (next to the gear in the top right).
   
3. Search for “OBS Studio” Plugin and click Get (it’s free!).
4. In OBS Studio, go to Tools > WebSocket Server Settings.
5. Check Enable WebSocket server (default port 4455).
6. Set a password (this allows Stream Deck to communicate with OBS).

💡 Tip: If OBS asks for a restart, that’s normal – go ahead and restart.

Step 2: Set Up .WEBM Alerts in OBS Studio

1. Open OBS Studio and select your streaming scene.
2. In the Sources panel, right-click > Add > Media Source. Name it something like “Sub Alert” or “Tumbleweed.”
3. Pro Tip: You can also drag and drop the file directly into the Sources panel.
4. In the properties window:
   • Check Local File and browse to your .WEBM file.
   • Uncheck Loop so it plays once. (Or leave checked if you want looping effects like Fire or Smoke.)
   • Check Restart playback when source becomes active (so it starts fresh every time).
   • Check Show nothing when playback ends (so the alert hides automatically).
5. Click OK.
   

Most alerts are 1920x1080 fullscreen, but you can pause playback to resize or reposition.

💡 Tip: Keep the source visible (eyeball icon on) and positioned above your other sources so the alert displays correctly when triggered.

Step 3: Configure Your Stream Deck Button to Trigger Alerts in OBS

1. In the Stream Deck app, find the OBS category (after installing the plugin).
2. Drag Media Source Control to an empty button.
3. In the settings:
   • Connect to OBS if prompted (localhost, port 4455).
   • Select your OBS scene and the Media Source (e.g., “Sub Alert”).
   • Set Action to Play/Stop. (Press once to play; press again to stop.)
     

You can also:

• Use Play/Restart to restart the animation with every click.
• Upload a custom icon for the button or choose from Elgato’s library.
• Create folders for different alerts (subs, bits, donations, etc.).

How to Test Your Stream Deck OBS Alerts

• Press the Stream Deck button → the .WEBM plays instantly.
• When it ends → it auto-hides, ready for next time.
• Press again → fresh playback, no overlaps.
