What is a capture card and how does it work?
A capture card is a device that connects to your computer or gaming console and captures the video and audio signals from your gameplay or other video sources. It then sends these signals to your computer, where they can be recorded, streamed, or edited. The capture card acts as an intermediary between your video source and your computer, allowing you to capture high-quality video and audio.
The capture card works by converting the analog video and audio signals from your video source into digital signals that your computer can understand. This process is called analog-to-digital conversion. The capture card also compresses the digital signals to reduce the amount of data that needs to be transmitted to your computer. This compression helps to reduce the latency and delay associated with capturing and streaming video.
Does a capture card add delay to my streaming experience?
