A capture card is a device that records or streams video and audio from an external source (like a gaming console, camera, or another computer) into your PC. It’s widely used for live streaming, video production, and gameplay recording.
🔎1. What is a Capture Card?
A capture card acts as a bridge between a video source and your computer. It takes the HDMI (or other video signal) from a console, camera, or DVD player, converts it into a digital format, and sends it to your PC via USB or PCIe. This allows you to record or broadcast high-quality video without relying on your computer’s built-in screen recording.
⚙️ 2. Key Features
- Video Input: HDMI, DisplayPort, or component cables connect external devices.
- Resolution Support: Many cards support 1080p at 60 FPS, while advanced models handle 4K HDR.
- Interface: USB 3.0 for portability, or PCIe for high-speed desktop integration.
- Low Latency: Essential for live streaming and gaming.
