Do you need a capture card?

The short answer

You need a capture card when the picture comes from another device: a console, a second gaming PC or a camera with an HDMI output. You do not need one when the game runs on the same computer as OBS, or when your webcam plugs in by USB: OBS takes those directly.

When you need one

A capture card turns HDMI into something the computer can record. You need it for:

• A PS5, Xbox or Switch through OBS. The console’s HDMI goes into the card, the card goes to the computer, and its HDMI output feeds your TV. If you only want to stream the game as it is, the console’s own broadcast needs no card: see the PS5 setup.
• A second PC that plays the game while the first one streams, so the game PC keeps all its power. See the dual-PC setup.
• A camera with clean HDMI as your webcam, for a lens and background blur a webcam cannot give. A small card such as the Elgato Cam Link 4K does it; check the camera first with the camera capture checker.

When OBS is enough

A game on the streaming computer goes into OBS through Game Capture or Display Capture, with no cable and no extra delay. A USB webcam and a USB microphone are already sources OBS can open. Adding a card to that setup gives you nothing but another box. The single-PC setup shows the route.

What a capture card cannot fix

A card moves a picture from one device to another. It does not change what the source sends or what your computer can take in.

• Copy protection: a console with HDCP on, or a video app, stays black through any card. Turn HDCP off on a PS5 under Settings, System, HDMI.
• A slow port: a 4K card on a slow USB port drops its large modes; the card cannot make the port faster.
• A camera that is not clean: menus and focus boxes on the camera’s HDMI output go into the stream; the camera has to offer a clean output.
• Audio routing: the card brings the console’s sound, not your party chat or your microphone; party chat routing covers that.

If you need one, which?

Choose by what you play at and what the computer offers. For a console played at 4K60 on the TV while the stream goes out at 1080p60, the Elgato Game Capture Neo passes 4K60 through and captures 1080p60. For high refresh or 4K capture on a fast, direct USB port, the Elgato Game Capture 4K X. Inside a Windows desktop with a free PCIe slot, the Elgato Game Capture 4K Pro. The best capture card guide and the capture card hub compare every current model. The setup builder checks a card against your computer and display.

Test it before the first stream

Connect the source to the card’s HDMI in, add the card to OBS as a Video Capture Device (how to set up a capture card in OBS has each step) and record a minute with the game moving. A black picture is almost always HDCP or the mode: capture card black screen goes through it in order.
