8 core coily cable

[Ashley Bradford]

Hi Guys

 

Just to clear things up from our side. In the PRO II Centerpost cable there were 4x 20 gage wires terminated in a 3B.308. In the new HD Centerpost cable we replaced each 20 gage wire with 3x 22 gage wires terminated in a 3B.856. This means there is a total of 12x 22 gage wires in the HD Centerpost.

 

Please call us if you have any further questions about this.

Regards,

Ashley

not to mention the two (2) independent HD-SDI capable coaxial video lines......

as does the XCS Ultimate (the first rig to do it...)

Just to be clear, the first rig to have three "HDSDI capable" runs was the Ultra 1 (Y2K), although they were somewhat makeshift in that they were connected into a 7-pin LEMO.

 

The Ultra2 has 1 clean HDSDI run with additional coax for RGB going into the 6-pin LEMO, i.e., creating 3 HDSDI capable runs. The Clipper324 has 3 clean HDSDI runs. The Phantom has 1 clean HDSDI run and 2 others into a 6-pin LEMO, and the Archer2 has 3 clean HDSDI runs.

 

"Clean" in this case means there is no break (connector) of any sort in the HDSDI line from the stage to the base. All the coax lines Tiffen uses are HD capable.

I know the thread is about coily cable but it's turned into a "my coil is bigger than your coil" thing -- funny stuff! Aren't we just using the image to viewfind? It's not like we are sending the image from the bottom of our sleds to a satellite (besides, I think we all saw at the monitor shootout that there isn't an hd monitor yet that can hold a candle to the popular greenscreens in one important aspect of our jobs...seeing a picture outside).

 

I understand the the power issues...but the video?! I am obviously missing something here (as usual).

Come on Ron. Don't you REALLY want a lisigav impregnated coily cable that has 12 lines of 4awg wire and 16 3G/HDSDI lines? I mean, what are you going to use for the dual satellite dish antlers? You don't really want to lose power in the middle of the shot because the automatic coffee maker came on do you? And what if you have to jumpstart your hummer from your sled? I don't think your current sled wiring is really up to that now do you?

Ron,

 

My feelings about HDSDI (and RGB) is that some operators really want the best possible color picture for their monitors, just like we all, I think, prefer nice optical viewfinders to the B&W low res things we are often subjected to with HD cameras.

 

Some cameras only output RGB ( and they are still being used)... and other cameras, like the Genesis, especially all up, benefits from large gauge wiring. We've had discussions about eliminating the "extra" coax lines and decided not to, because of those cameras, and because the lines can also be used for any other signaling purpose - such as audio up and down the post - a McConkey thing.

 

So IF any of these things are important to an operator, he/she might want to consider sled A vs. sled B. Big IF.

 

What's useful is that we now know that most of the major branded rigs have both HDSDI coaxes and fat power wiring. That is good for everyone to know.

 

I posted the info re the Tiffen curly cords because we worked hard early on to give Tiffen sleds high current and RGB/HD video capability (BTW, it's part of the Ultra's patent that GB came up with), so the claims of "first" seemed a bit... uninformed and off-topic.

The analogy of the optical vs the new pos viewfinders we have to deal with today is a good one, but when we use these optical finders we aren't really self-navagating through sets, up/down obstacles with our eyes frequently leaving the picture to check what is coming up etc.. I totally get that some require the best possible picture, but there is only so much info we can process even while doing even simple steadicam shots. When on a dolly or sitting a the dit station studying the image this would be a different story. I guess I am in awe of the ops that actually must have this superior image to compose some characters in a box. I actually prefer my greenscreen and have had good luck with it...excepting the occasional deranged director who will sometimes yell out "follow the one in yellow" in the rolling rehearsal. I have only recently delved into the murky and hard to see world of lcd viewfinding and find it very frustration...but wow is it a clear picture -- I only wish I could see it!
