S-Video Cable
A generic video cable supporting s-video, composite, and stereo audio, for multiple generation of Nintendo consoles.
Description
This S-Video Cable provides improved image quality for a range of Nintendo consoles that use the Multi AV port, a proprietary connector that allowed different types of analogue video cables to be attached. First introduced with the Super Nintendo/Super Famicom, which coincided with the move away from RF outputs, the plug remained in use up until the GameCube. Notably only the NTSC version of the GameCube would output an s-video signal.
Despite the cables bundled with consoles usually being composite (yellow video + red/white audio), Nintendo long supported higher‑quality outputs such as s‑video and RGB (SCART in PAL regions). This cable plugs into the Multi AV port on one end and provides an s‑video connector plus stereo RCA audio on the other. The advantage of s‑video is that it separates the video signal into two channels: luma (brightness) and chroma (colour), which reduces colour bleeding and dot crawl compared to composite. The result is a noticeably sharper image, especially on CRT televisions or capture devices that accept s‑video.
These cables were widely available from third‑party manufacturers, inexpensive, and often included both s‑video and composite connectors on the same lead. Their build quality can vary, but functionally they all rely on the same pinout of the Multi AV port, and result in an improved image. I used to sell 100s of these leading me to believe more people cared about image quality than we were lead to believe. Although it may not match the RGB output through high end scalars of today, it provided a substantially better quality than the average person experienced back in the day.
