If you have an all-in-one style capture device that does both video and audio, especially one over USB, then hooking it up is a no-brainer: just connect everything to the capture device. You don't have a choice anyway. If you have a "TV tuner" style device, though, then some of the capture work is also being done by the sound card, and you have to hook up a couple of cables to get everything working. Capturing from cable (coaxial input)In this scenario, you have a TV tuner type capture card and want to capture from a TV channel.
The TV tuner card accepts the cable input, selects and decodes the desired channel, captures the video, and splits off the audio for your sound card to capture. Capturing from audio/video outputsIn this scenario, you have a TV tuner type capture card and want to capture from another device that has separate audio and video outputs, such as a VCR or video game console.
The problem you will often encounter here is that the output device will have a pair of round RCA connectors, one for each of the left/right stereo channels (red and white), while the capture and sound cards will have 1/8" mini-stereo inputs. A cable with a male 1/8" on one end with stereo RCA male connectors on the other end, along with a pair of RCA female-female adaptors, will help you hook everything up here. This assumes that you have a capture card that has integrated audio capture. If your capture card simply passes through the audio, it's better just to connect the audio output directly to the sound card:
This shortens the audio path for better quality, and you won't have to worry about whether the capture card's audio mixer is set to the right level or the correct input. |
