How do you use a video capture card?
There is a lot of overlap with tuner and capture cards, and most tuner cards have a built-in capture device as well. Here is the key difference: – A tuner card connects directly to a TV source and decodes, plays back and/or records the chosen TV channel. Possible TV sources include a direct connection to an antenna or to the cable outlet. – A capture device connects to the output of a video device (typically an analog video output). This allows you to record directly from devices like camcorders, TV set-top boxes and game consoles. Capture cards that record from digital (HDMI) sources are rare because the industry enforces copy-protection mechanisms that legally prevent certain content from being recorded (even though it is possible from a technical standpoint) and there are a lot of copyright legal issues involved that most companies don’t want to deal with.
