A capture card, also known as video capture card, capture board, or video capture board, is an expansion card that enables video capture functionality.
A capture card is a device that captures images from a video signal from a TV or other device, and is a peripheral device that plugs into an expansion slot.
The capture card enables the capture of video and audio from televisions and other audio/visual equipment, allows it to be saved, and converted into a format that can be handled by a computer.
In recent years, capture cards has been used for video distribution on YouTube and other video sites.
In particular, capture cards are very often used for live video games. With capture cards, the screen of a video game console can be projected onto a computer for recording and live distribution, but without capture cards, this is not possible on a computer in principle.
In this case, the term "game console" refers to the Nintendo, PlayStation and Xbox devices, for example.
Note that capture cards are not required for PC games.
Capture cards have two functions: one is to capture video signals as moving images, and the other is to capture still images.
Some are integrated with the video card, while others have only capture functions.
Special software is used to perform capture.
Sound capture cards are also available to capture sound in high quality.
In the example of a game console, by connecting the game console to the capture cards, the game screen will appear on the computer screen and the game sound will also come from the computer, making it possible to play the game while watching the computer screen.
By connecting a game console to a capture board in this way, not only can the game console screen be projected onto the PC as described above, but it is also possible to record games, create live video clips, and live-distribute them.
To record the distributor's voice, a microphone must be connected to the computer and set up, and to distribute live, distribution software is required.
