Will there be a difference in picture quality if a short RCA/phono cable labeled "audio" i

Sales people claim that the RCA/phono cable labeled "audio" will not work for carrying video a very short distance (less than a foot). The "audio" cable will be used to interconnect two yellow-colored "video" RCA/phono cables. My concern is video picture quality will look much worse than if expensive cables labeled "video" are used.

I'm sure the AV-philes will cringe at this, but in most situations, a RCA cable is a RCA cable is a RCA cable.

There is no difference, electrically, between the red, white and yellow RCA cables. The color coding is just to help you make sure you keep your cables in the right order.

However you may also notice that there are component video and coax audio cables which also use the same RCA connectors. While these cables use different colors as well, they are still basically the same as the good old yellow, red and white cables you are familiar with. These cables will have slightly better electrical properties, but for short runs you can often get away with just any RCA cable. Nothing. No difference except the color. The colors are so you don't plug an audio jack to a video jack. But if I understand correctly you just want to use say a red audio cable to connect two yellow video plugs. That is OK you will not see a difference the wires are exactly the same if you take them apart. Good luck. I have done this in the past, over an even greater distance (the cable was 6 feet). I could not perceive any difference in quality on a standard TV. An audio cable is just that for audio, it has a signal, return and a shield. Video is video
