RCA to BNC Cable( JVC GY-HD110 Multibridge Extreme)

I have the JVC GY-HD110 and the BlackMagic Multibridge Extreme.
I would like to capture unconpress video but I don't know which RCA to BNC Cable brand will give me the best quality.
A the monet I found the 3ft Sonicwave for $ 55.99.

Save yourself some money.

Buy a regular component cable from your local electronics store for about $20. Order some BNC male to RCA female connector ends from Markertek or any other manufacturer (http://www.markertek.com/SearchProdu...f=10&sort=prod) .

They adapters cost just $2 each and will work for any level of production work.

Or you could order a BNC component cable and then buy some BNC female to RCA male connector ends.

Either way, you'll save at least $20 by the time it's all said and done if you use connector ends rather than a custom cable. Anything custom always cost more.

Sigh, another person falls for the Monster Cable marketing BS. 75 Ohm coax is about 62 cents a foot if you buy in bulk. Spending seven bucks a foot for a "premium" cable gets you nothing except a significantly lighter wallet.

I would say there is a difference between cheap cable and connectors and high quality cable and connectors... but that said, the real expensive cable includes a lot of marketing cost and premium charge for the "name." There are differences in the shielding and the quality of the connections with the connectors, and the connectors as well.

However, if I were using a cable off the camera day in and day out, and the camera had BNC connectors, I would want to pay the extra for a cable with BNC connectors. If you put on a BNC adapter, then plug in an RCA cable, what's the point of the BNC connector on the camer in the first place.

Also, the extra length of the hard metal with the adapter is not desireable to me.

If you are just making a one time connection for some purpose, I suppose it wouldn't matter how you did it if you had good connections and got your signal through. However, as part of a standard camera setup, I would want a nice cable with the right connectors, and a cable of the right length and the right flexibility to make it all as slick and well-working as possible.

Good connection

Jack,

That is what I thought, I have some very good RCA cables and the BNC adapters but I would like to get the best cables for this project.

What cable length should I get for better quality?

Links to the product would be great!!


Thanks!!

you're really worrying about nothing. unless you plan to run a hundred plus feet, the differences in cable are usually not in any way significant. I've wired a couple of master control rooms, who knows how many edit suites, and I can tell you there is very very little difference with this stuff in short runs - meaning under 100ft unless you are using the worst junk. just because a cable is thick doesn't mean anything. there are some cheap cables that look like good ones and are simple filled with plastic/foam. I get coax RG-59 for around .25/ft and matching connectors are under $2ea. you do have to invest in all the crimping tools for around $50, but when making hundreds of cables, the savings is huge. in your application, there will not be any difference between a 3ft or 6ft cable or a 10ft cable

in fact, as far as cables being used with the camera, I'd use mini-coax in a mini snake cable. I'd use as light a cable as possible to reduce stress on the RCA's on the body. using a heavy coax cable will not be a good thing.

I probably wasn't clear.

When I say quality cable, I am making a comparison of say the digital grade coax cable as compared to the cable that comes free with the $69 TV.

I just mean that a professional grade (not a consumer rip-off grade) is actually better than the cheap-cheap grade that looks the same.

As far as connecting to the camera... I want a lightweight, flexible, bundles cable. I want a connector that matches the connection on the camera so that there isn't an extra 1-1/2 inches of metal adapter sticking out to bump into. If you have BNC connectors on the camera, I think a BNC connector cable is preferable... as opposed to an RCA connector adapter on the BNC connector, then an RCA cable. If the RCA cable was superior, I think it would be put on the more expensive camera.

To make a comparison to audio. If I were setting up a one-time arrangement, I would use whatever connectors and mic cables did the job. But, if I were making a permanent cable arrangement on a recorder/mixer.wireless setup in a briefcase, I would use the best cables that would give me the neatest and easiest to use package, with professional quality components that would work day in and day out.

Bottom line, it's not necessary to spend a lot of money on cables. But it is desired to pay attention to get professional quality cables of a reasonable price with the correct connectors. It will pay off in the long run, and it will only cost a little more than cheap cables connected with various adapters.

I've built a quite a few cables myself (I prefer to do this - over the years I've easily paid for the specialist tools involved many times over) and the one thing you must do with coax is use a solderless plug. Most BNC plugs are designed for crimp connections, most RCA's aren't. Canare do make an excellent true 75ohm RCA that will crimp with a standard centre pin and barrel. Strong and sound.
