We use this to take a composite output from a camera to usb in on the computer.
This is a very cheap way to connect a camera up to a PC without the need of a capture card.
It also has audio and s video connections but as yet I have not tested these. I hope that I can take an XLR output from an amp to stereo phono so that video and audio can easily be connected via USB. This will allow for roamingradio mics connected through an amplifier to be recorded. I will report back on this. I have not done any comparison of quality but I suspect that something like an Osprey card will be of higher quality. I intend to make some comparisons
