What is the main purpose of a capture card?

The primary function of a capture card is to record video signals on a computer. Capture cards are devices that allow the transfer of video data from an external source, such as a gaming console, camera, or other video outputs, into a computer. This capability enables users to create content, such as live streaming games or recording video presentations, by capturing high-quality video feeds and encoding them for processing or streaming.

This option is vital for anyone focused on video production, gaming, or streaming, as it provides the necessary hardware to ensure that video can be recorded and manipulated on a computer system. The quality of the video captured is influenced by the specifications of the capture card, making it important for producing professional-grade content. In contrast, audio output enhancement, RAM performance upgrades, and graphic output modifications are unrelated to the specific function of capturing video signals.
