No matter when you are on your journey as a live streamer, ensuring high-quality content and seamless performance is essential for keeping your viewers engaged. One tool you can use to achieve the utmost quality is an HDMI capture card—a device that allows you to connect external video and audio sources to enhance your stream quality.
But what exactly is it, and how can it elevate your streaming setup? Let’s dive in.

What Is an HDMI Capture Card?
An HDMI capture card is a device that captures video and audio signals from external sources—such as gaming consoles, cameras, or other HDMI-enabled devices—and transmits them to your computer for streaming or recording through software such as Streamlabs Desktop. Think of it as a bridge between your source device and your live streaming software.
How It Works:
- Connect the output of your device (e.g., a gaming console or DSLR camera) to the capture card via HDMI port.
- Plug the capture card into your computer.
- Use your streaming software (like Streamlabs Desktop) to process and broadcast the video signal to platforms like Twitch, YouTube, or Facebook.
However, it’s important to note that software such as Streamlabs Desktop and Streamlabs Console allows you to connect cameras and gaming consoles, respectively, without requiring a capture card. For example:
Cameras: Many modern DSLR and mirrorless cameras offer USB connectivity, letting you use them as a webcam without the need for a capture card.
Gaming Consoles: Streamlabs Console, specifically designed for console streaming, allows you to stream directly from your Xbox to platforms like Twitch without extra hardware, such as a PC or capture card.
There are also two types of HDMI capture cards: external and internal.
External capture cards are standalone devices that connect to your computer. These are portable and easy to set up, making them ideal for streamers who frequently switch between devices, travel, or prefer to put away setups between streams.
Popular Example:
- Elgato HD60 S+
Internal capture cards are installed directly into your PC via a PCIe slot. They are often more powerful and better suited for professional streaming setups requiring high performance and minimal latency.
Popular Example:
- Elgato 4K60 Pro
How an HDMI Capture Card Can Improve Your Live Stream
There are a few key ways an HDMI Capture Card can improve your live stream experience for you and your audience.
Higher Video Quality
Capture cards allow you to stream in high resolutions, such as 1080p at 60fps or even 4K, without the worry of compressed video quality. This ensures your stream looks crisp and professional, particularly for gaming content.
Ability to Use High-Quality Cameras
Want to elevate your visuals with a DSLR or mirrorless camera? An HDMI capture card makes it possible to use these cameras in place of your webcam.
Although, in some cases, you can connect a DSLR camera to your streaming setup without one (with the use of webcam utility software), a capture card allows you to unlock the full potential of your camera by transmitting uncompressed, high-resolution video signals. In some cases, a capture card may help maintain full manual control over camera settings like aperture, shutter speed, and ISO, which are sometimes restricted or overridden by webcam utility software.
Low Latency Streaming
Modern capture cards are designed for low-latency performance, reducing stream delay between your gameplay or video feed and what your viewers see. This is critical for maintaining engagement, especially in competitive gaming streams.
Again, live streaming software such as Streamlabs has features to help with low latency, but capture cards take it a step further by offloading processing tasks from your computer, ensuring smoother performance.
Do You Need an HDMI Capture Card?
Not every streamer requires a capture card. Here’s how to decide:
You Might Need One If:
- You stream console games (e.g., from a PlayStation or Xbox).
- You want to use a DSLR or mirrorless camera as your webcam.
- You prioritize high-resolution, professional-quality streams.
You Might Not Need One If:
- You stream PC games directly from your computer.
- You use a standard webcam and don’t require additional input sources.
- You use software such as Streamlabs Desktop or Streamlabs Console that allows you to stream via DSLR and gaming console without the use of a capture card
No matter where you are in your streaming journey, understanding the tools available to you is essential for enhancing your content. While a capture card isn’t always necessary, it can be a powerful addition to elevate your video quality, reduce latency, and unlock the full potential of your setup.
