This transition has affected all of the technology that brings live streams to life. ![]() ![]() Over the last ten years, the video industry has transformed from Standard Definition (SD) to High Definition (HD), to Ultra High Definition (Ultra HD or UHD). The Technical Background of Video Capture Devices Video switching software packages like Wirecast or vMix are a perfect match for cards with multiple capture channels for multi-camera webcast production. This higher performance also allows for multiple input channels on one device. These cards have the benefit of being connected directly to the system, which enables higher performance. There is also the small form factor, Mini PCIe version or Newer M.2 standard. They usually connect through the PCIe adapter slot inside a desktop or rack system. The latter is preferred since it is easier to use since it doesn’t require the support of drivers. These include USB devices that need their own software to work and PCI Express (PCIe) ones that support plug-and-play. There are two main types of video capture devices. The reason that broadcasters use video capture devices is to connect their external stream sources to the video streaming platform that is operating on their computer. Video capture devices are mostly used with PCs, but they can work with laptops that have the proper ports. What is a Video Capture Device? Video capture devices are also known as video capture cards.Ī video capture device, which is also called a “video capture card,” is a piece of hardware that connects your live streaming camera to your computer. Best Video Capture Devices for Live Streaming.How to Choose the Right Video Capture Device.The Technical Background of Video Capture Devices.Therefore, it is preferable to use high-quality professional hardware capture cards capable of digitizing video streams even in Full HD quality. In video conferencing it is very important for a signal from the camera to be transmitted and digitized without any delay and in real time. This type of card is much cheaper than the first and performs conversion by using the CPU’s capabilities. Most of them are equipped with a TV receiver. Capture cards without hardware video compression.It is possible to relieve a computer’s CPU by using hardware compression cards. Such cards are the most expensive, because they can quickly digitize video data without using the CPU. They digitize analog video and compress it into formats such as DV and MPEG-2 “on the fly”. Capture cards with hardware video compression.To digitize an image, a capture card has to be connected both to a computer and a camera in order to transfer the signal. It will serve as an interface between the devices. If the PC does not have an HDMI-input (do not confuse with HDMI-output), it is necessary to connect the camera to a capture card in order to convert analog signal into digital (or vice versa). ![]() Such devices make it possible not only to convert analog video signals to digital, but vice versa too. Modern capture cards often use several algorithms for video compression at once. Capture card or digitizing card is a device that is capable of digitizing video signals through certain interfaces (e.g., HDMI, USB, S-Video, or other analog input) and storing the results on a computer using various compression algorithms (typically MPEG1, MPEG2 or MPEG4). ![]()
