can i use a red rca cable for video
They are often color-coded, yellow for composite video, red for the right audio channel, and white or black for the left channel of stereo audio. This trio (or pair) of jacks can be found on the back of almost all audio and video equipment. One or more sets are often found on TV sets to facilitate connection of camcorders, other portable video sources and video game consoles. Although nearly all connectors, including analog and S/PDIF audio as well as composite and component video, can use identical 75 Ω cables, sales of special-purpose cables for each use have proliferated. Varying cable quality means that a cheap line-level audio cable might not successfully transfer component video. For digital audio, as long as a connection is successfully made using the cables the sound will remain faithful to the original signal because a digital signal can only be fully received or not received at all. Cables should meet the S/PDIF specification as defined by the international standard IEC 60958-3 for assured performance.
