How to Choose a Capture Card for PS5 and Xbox Computer Vision

How a capture card fits into a vision setup

The console’s HDMI cable goes into the card’s HDMI In. The card sends the signal unchanged out of its HDMI Out to your TV or monitor, which is called passthrough, and at the same time delivers a copy to the PC over USB or PCIe. On the PC, any capture app, from OBS Studio to a Python script using OpenCV, reads those frames.

That gives you two paths with different limits. The passthrough path decides what you see and play on. The capture path decides what the computer sees: its resolution, frame rate, pixel format and delay. For computer vision the capture path is the one that matters, but a card with weak passthrough will still hold back your TV picture. The console computer-vision setup guide shows where the card sits in each of the three common setups.

USB vs PCIe and driver-free UVC cards

USB cards are external boxes that work with desktops and laptops. Most current USB models are UVC (USB Video Class) devices: Windows loads its built-in driver and the card shows up like a webcam in any app. Elgato lists the HD60 X, 4K S, 4K X and Neo as UVC devices. PCIe cards sit in a desktop’s x4 slot, need the maker’s driver and avoid USB bandwidth limits entirely.

Bandwidth is the reason 4K cards want faster ports. Uncompressed video in the common NV12 format uses 12 bits per pixel, the YUY2 format 16 bits:

A 5 Gbit/s USB port carries less than 5 Gbit/s of actual video after protocol overhead, so uncompressed 4K60 does not fit. That is why the Elgato 4K X asks for a USB 3.2 Gen 2 (10 Gbps) port and Elgato notes that a 5 Gbps port works only with reduced capture resolution. 1080p60, the usual feed for vision work, fits comfortably on any real USB 3 port.

Passthrough: 4K60, 1440p120, 1080p120, VRR and HDR

Passthrough should match how you play. The PS5 supports HDMI 2.1 with 4K at 120 Hz, VRR and HDR, set under Settings > Screen and Video > Video Output. On Xbox Series X|S the equivalent is Settings > General > TV & display options, with VRR under Video modes.

• HDMI 2.0 cards such as the Elgato HD60 X and 4K S pass through up to 2160p60, 1440p120 and 1080p240, with VRR and HDR10 up to 4K60.
• HDMI 2.1 cards such as the Elgato 4K X and 4K Pro or AVerMedia’s Live Gamer 2.1 models pass through 4K at 144 Hz or more with VRR and HDR.
• If you play at 4K120, only an HDMI 2.1 card keeps that on your TV.

Passthrough and capture are not the same number. Elgato’s matrix for the HD60 X shows that with a 4K60 input it captures at most 4K30 or 1440p60 in SDR, or 1080p60 in HDR. Always check the maker’s input-to-capture table for the console mode you actually use. HDR capture on these Elgato cards works on Windows only; for vision work an SDR feed is usually simpler to process.

Capture resolution, frame rate and latency

Vision models rarely need 4K. Many detection models work on inputs around 640×640 pixels, so a 1080p frame already carries more detail than the model sees. Frame rate matters more: at 60 fps a new frame arrives every 16.7 ms, at 120 fps every 8.3 ms. If your PC can process frames that fast, a card that captures 1080p120 halves the wait for fresh information.

Passthrough adds no noticeable delay, but the capture path does. Elgato quotes preview latency as low as 30 ms for the 4K S on capable setups and 50 to 100 ms for the older HD60 S+. Software buffering, format conversion and your own processing come on top. Elgato and AVerMedia both market their PCIe cards for low delay thanks to the direct connection to the motherboard. The input latency guide breaks down every stage of the chain.

Current capture cards compared

For a vision setup on one PC, a UVC card like the 4K S is the simplest choice. Choose a 10 Gbps USB or PCIe card when you want 4K120 passthrough or capture above 1080p120. If you use IRONICS, its computer-vision modules need a capture card in every setup, with or without a Titan Two; the setup guides on our Discord (discord.gg/ironaim) include capture card recommendations.

HDCP on PS5 and Xbox

HDCP is copy protection on the HDMI link. Capture cards cannot record an HDCP-protected signal; you get a black picture. The PS5 enables HDCP by default, so turn it off once:

1. Connect the PS5 directly to your TV, without the capture card.
2. Go to Settings > System > HDMI and switch Enable HDCP off.
3. Connect the PS5 to the card’s HDMI In and the card’s HDMI Out to the TV.

Xbox Series X|S consoles do not apply HDCP to games. According to Elgato they switch it on only when an app that requires it opens, such as Netflix or Hulu. If the picture stays black after using a streaming app, restart the console. Streaming apps and disc playback can never be captured on any console.

Recommended OBS and Windows settings

• In OBS, add a Video Capture Device source, set Resolution/FPS Type to Custom, then the resolution and FPS the console actually outputs, for example 1920×1080 at 60.
• Set Video Format to an uncompressed option such as NV12 or YUY2 where the card offers one; compressed MJPEG costs CPU time to decode.
• Set Buffering to Disable for the lowest delay. OBS notes that enabling it can help if you see stuttering.
• In Windows, turn on Settings > Privacy & security > Camera > Let desktop apps access your camera, because UVC cards count as cameras.
• Plug the card into a USB port directly on the motherboard with the cable that came in the box; USB-C cables that ship with phones can be USB 2.0 only.
• Close other apps that use the card before starting your vision software, so only one program opens it.

The rest of the PC matters too: GPU, CPU, RAM and free USB controllers. See PC requirements for real-time computer vision.

Common problems: black screen, stutter, USB bandwidth

If a desktop has no USB 3 controller at all, Elgato recommends adding a USB PCIe expansion card. For the capture card itself, the rule stays simple: stable 1080p60 or 1080p120 into the PC, passthrough that matches your TV, HDCP off.
