I am making a few video cables to work between my HDV camera and a High Res monitor. Does anyone know the resistance value they need to be to get the correct image? Does it even matter? I want to make both composite and component ones.
A dull but important question

Its impedance your looking for, not resistance. (a coper wire at those voltages, in theory given a direct current should have very very little resistance.) For regular video its around 75ohms, I am not sure If there is a difference when going to HD component video. I would imagine given the higher frequency signal you would need lower impedance. I would go out to best buy find the $300 monster cable that does what you want it to do, and look at the jacket of the connecter. Almost always monster cables prints the impedance on a band around both jack. Check all cables, there may be a different impedance between the lumanance and chroma channels, due to pixel subsampling.
