Which connector is commonly used to carry video signal only in professional setups?

• A. RCA Cable
• B. HDMI Cable
• C. BNC Cable
• D. 1/4" Phone Plug

Answer: (C)

In professional video work, the connector chosen for carrying a video signal reliably is the BNC. It’s built for coaxial video with a defined impedance (usually 75 ohms), which helps preserve image quality over cables. The twist-lock design keeps the connection secure on busy sets and in racks, so video signals don’t drop during shoots. While RCA is common for consumer video, it lacks the robust impedance control and locking needed in studios. HDMI carries both video and audio digitally and isn’t used for a dedicated video-only path in pro setups. The 1/4" phone plug is primarily for audio, not video.
