A frame grabber can be either a portable device that connects to a computer via USB or a stationary card that connects to a PCI slot and grabs video from virtually any source. (It may or may not be feasible to capture audio depending on the source and the connection.) After that, you may record video into your computer from the many sources you have, and then stream it using a variety of third-party apps. A capture tool can make it easier for you to gather data from sources that are non-standard or specialized while you’re working with frame grabbers.
Video may be captured by frame grabbers from practically any type of interface, including HDMITM, SDI, DVI, and VGA. You might be able to seize devices such as cameras, other computers, tablets, mobile phones, medical equipment, electronic microscopes, specialized hardware, and scientific apparatus. Utilizing the capture tool, you might be able to set unique parameters in order to assure compatibility with even the most specialized video sources. This capability is dependent on the video source you are using.
