Your camera has one RCA video out and one SVideo out. Your monitor has S Video and BNC in.

You have choices and looking at the prices the methods aren't much different in cost.

You either buy an S Video cable

an male RCA to BNC

a male RCA to male RCA with a BNC adapter

All will be within $10 of each other for a 50 ft cable. The difference between 50 and 25 ft wasn't that much either.

The RCA or BNC will give you less rez but does that really matter in the field ?

I think it matters, for checking focus and for ensuring that important small details are resolvable.

And, it's not just resolution that's lost; chrominance bandwidth is cut as well.

This local place tried to sell me 50 ft of Svideo cable for 89 dollars, and 100ft for 150 or something. It was thick round cable, and they said they didn't have any lesser grade. Guess it's off to B&H. How'm I supposed to give local merchants my business when they won't accomodate my needs?

Texas dealers for Hosatech

I already gave you the links for the cable.

BNC Cables
The cables that I described earlier are true 75 ohm broadcast quality and maintain a clean signal through 200 ft runs whether it's composite (RCA) or Y/C Component (S-Video). There are pictures of the reels and cables at the links below.

Is the difference in signal (s-video vs. composite) really important in the kind of work are you are doing. I'm of the opinion that the difference in signal is so small that it doesn't really matter, as long as the recorded signal is maximized. In my organization, we've used compoSITE signal to monitor the compoNENT signal coming from a Beta-SP cam, and I can't say that the couple of extra grains of noise or whatever bothered us.

The BNC-standard (Robert: I've heard that it's short for bayonet-Neill/Concelman, the guys that invented it) does the job every time, and especially in the field, or when doing live mixing. The danger of broken connections and worn plugs should be avoided, and the S-video DIN-standard is physically too weak. It's not so much the quality of picture, but the reliability of the connector that's important. How ever, in postproduction you could use whatever standard you like I guess, although I can't see that most of us would need to have any better than composite to monitor our video.

Everyones right, hows that?
"Bayonet Neil-Concelman" or "Bayonet Navy Connector" or "Baby Neil Connector"



Josh, just use what make you happy, you're the one that counts. Let me know if you were able to source those locally.

Josh Bass June 8th, 2003 11:34 PM

I want whatever gives me the objectively highest quality signal. I went with B&H.

Interesting (BNC)
How on earth can a sipmle three letter acronym stand for all this? What does the plug in question have to do with babies, nipples, nuts and the british navy?

Bayonet Neill Concelman connector
Bayonet Nipple Connector
Bayonet Nut Coupling
Baby N Connector
British Naval Connector

The BNC connector is also known as RG58

However, I just found this piece of text on the net explaining the origin of the BNC, and I calmed down:

It's a secure connection, does the name really matter. My point was , it's no big deal what the letters stand for.
