How to stream WASP3D Livestream overlays in OBS?

Streaming WASP3D overlays into OBS works almost the same as vMix. OBS also supports NDI, SDI (key + fill), or browser sources, depending on how you output graphics from WASP3D.

🔹 Method 1: NDI Integration (Recommended)

This is the easiest and most common method.

  1. Enable NDI in WASP3D

    • From WASP3D On-Air/Playout, output your graphics as an NDI source.

    • Make sure WASP3D and OBS are on the same network.

  2. Install OBS-NDI Plugin

    • Download & install the OBS-NDI plugin (required for OBS to detect NDI feeds).

  3. Add NDI Source in OBS

    • In OBS → Sources → Add → NDI Source.

    • Select the WASP3D feed from the dropdown.

  4. Overlay on Camera Feed

    • Place the NDI input on top of your video layer.

    • OBS respects alpha (transparency), so lower-thirds, tickers, logos, etc., will appear cleanly.

🔹 Method 2: Fill + Key (Video Cards)

Used in professional broadcast setups.

  1. Output Fill + Key from WASP3D (requires DeckLink / AJA cards).

  2. In OBS, capture the DeckLink input for Fill and Key.

  3. Configure chroma/luma keying in OBS to merge the transparency.

(This requires more hardware, mainly for SDI workflows.)

✅ Best Practice for Streaming:
If you’re streaming online (YouTube, Facebook, Twitch, etc.), NDI + OBS is the smoothest workflow. No extra hardware is needed, and it’s real-time with transparency preserved.
