A video capture is the process of transferring the video you recorded from a video camera or other video recording device (such as a cell phone), to your computer. This process is done by attaching the video camera to your computer, with a special USB cable (which usually comes with the camera on purchase). A variety of computer software programs can be used to then start the video capture process, which copies the video clip(s) from the video camera and stores it/them on your computer as a digital file(s).
The use of a USB cable is not the only method of capturing the video from the device. Other digital video devices can capture video and transfer them to your computer by a standard serial or parallel cable. However, these are not the most commonly used tools.
