Composite Video vs. S-video — What's the Difference?
By Tayyaba Rehman — Published on February 11, 2024
Composite Video and S-video are video signal formats. Composite combines all signals into one, potentially degrading quality. S-video separates signals, providing better quality by keeping brightness and color information separate.

Key Differences
Composite Video, a common connection, combines all video signals into one cable. It transmits video, sync, and color information through a single channel, but this amalgamation can result in signal interference and reduced picture quality.
S-video, or Separate Video, improves on Composite by transmitting brightness (luminance) and color (chrominance) signals separately. This separation reduces signal interference and enhances image quality. S-video connectors have separate pins for luminance and chrominance, ensuring clearer and sharper visuals.
Composite Video suffers from color bleeding, where color information can bleed into areas of the image. S-video's separation of luminance and chrominance signals prevents color bleeding, resulting in sharper images, especially noticeable on high-resolution displays.
In terms of cable complexity, Composite uses a single cable, simplifying connections, but at the cost of potential signal degradation. S-video, with separate luminance and chrominance cables, provides a cleaner signal but requires additional cables for connection.
While Composite Video is widely compatible, found in many consumer devices, S-video is commonly used in higher-end equipment, offering improved image quality, making it preferred for professional audiovisual setups.
