What is video and audio capture?
Capturing video and audio refers to recording and storing them as digital format files. Video capture devices are categorized into software compression (soft compression) and hardware compression (hard compression). The difference is that soft compression relies entirely on the computer CPU for processing, whereas hard compression utilizes a built-in core chip, significantly reducing CPU usage and enhancing capture performance. Desktop computers can use software compression capture cards, while laptops can use USB interface software compression capture devices. For independent operation without a computer, hardware compression standalone recording products are available.
