Flying 3D rigs?

Thanks Chris for the info update.

 

What Sled is that? Some kind of Satchler?

 

Personally with 3D I happily take one feed for my monitor. Transvideo have 3D monitors, for which there are plenty of applications, but I don't think it will take off for camera operators. You can also always start putting different feeds at video village through video mixers dropping various colour channels but I wouldn't bother.

 

I have always had to go hard wired. I suppose there may be a day ,with 2 scarlets or epics on board, that you'll carry two HD transmitters. Until then, I assume you'll be hard wired on most setups apart from dual REDs. If I had a dual RED tomorrow: I would transmit one picture or hard wire two.

I'm digging the anaglyph glasses, Alfeo. That's gotta be awkward walking and balancing while looking through those things? Was that necessary or you just wore them for fun? I would think you could send a single camera to your monitor and that would be all you really need. Though this brings up an interesting question about transmission...

 

Did you have two separate transmitters so the shot could be viewed in 3D back in the village? Then again, would you want to (two static-y broadcast signals being paired together)?

That was the Transvideo 3D monitor which I do like, but it didn't feel to awkward wearing the anaglyph glasses. I will say, if you get a 3D job that will use 3D monitoring, try to get a custom pair made just for you (with backups). I've used it twice on two separate occasions and enjoyed the experience. In terms of the single camera feed to your monitor, depending on the proximity of your subject, your framing for the left eye may not lend itself to a good frame for the right eye, unless the subject is at the point of convergence. On a parallel setup with two REDs, I put the two LCDs side by side and viewed cross-eyed to see the 3D image. This helped tremendously with my compositions and edge violations. I will say that I was shocked to see how bad my framing was when I looked at the 'single eye' ruff cut.

 

No video village on all THREE of my 3D setups... everyone was at the camera (small and fun times).

Thanks Alfeo,

 

But if the subject is that close surely your interocular distance should not be so big as to dramatically effect the right eye. I suppose if we are using side by side rigs with their large minimum interoculars rather than mirror rigs then it becomes more important. Its interesting that you have enjoyed using the 3D monitor. But still the 3D effect has still not been fine tuned, this is a raw version and there is studio tweaking that still needs to be done. I don't want to go through that grief/headache. Those guys when they sit down for the fine tuning have massive bags of paracetemol and suffer huge migrains. If the interocular distance is correct surely you should not have to see the other eye unless its important for one reason or another. I would actually rather have two monitors next to each other.

 

Chris, Yeah it looks like all you would really need to do is turn your topstage backwards.

After seeing the framing in one eye and knowing how important that is to an operator and his livelihood, I would NOT want anyone to judge me on one eye only, especially on a parallel rig with a large minimum IO. God forbid they deliver dailies from the opposite eye than you framed from. If I can monitor both at a time, I will... remember that bogies are only inches outside our frame(s).

You might get lucky and fly Paradise FX's SI2K beam splitter 3D rig. Weighing in a hefty 18lbs you might have to add some weight or remove some canisters. Ill try to get a few pics of the rig.

 

Is this the Paradise FX rig to which you speak?

It seems small and at 18lbs it is lightweight

That is the old Paradise FX rig which was designed to be able to fit inside the MKV-AR. The new one is a little bit different. It has two MDR's on the bottom which control IO and Convergence but its roughly the same size and shape.

The Element Technica Red 3d rig weighs about 100 pounds... not possible on a Steadicam. The Pace 950 rig was at the max I wanted to use on a rig. The choice was made to use Copper instead of Fiber when possible... like having to Garden hoses attached. I was just able to mount the Pace F23 rig, but stressed that is was not really practical to use. The 950 rig had a custom bottom to compensate for convergence pulls.

 

So was the Pace F23 rig able to hold on your arm? Or did you need to add extra muscle to hold it up. It does seem incredible that you were able to fly two F23 s.

I've flown the Paradise FX 3D rig and its awesome. It is very light. Of course you have the cables to deal with but if you are gonna do 3D it is a dream for steadicam. Its the camera used on "My Bloody Valentine". I believe it was made to fit in a AR so that should tell you that it is very small. I used it on my PRO 2 rig and it honestly was almost too light. Id say it was about the same as flying a SR3 but cabled up. No problem with Convergence weight change either. Everything moved together and balanced really well.

I don't know if we will have the option to use the Paradise FX rig that often which is going to be marketed as the Elemental Technika Neutron in the second quarter of this year. Currently you can only use the Schneider 8mm C-Mount lens and possibly a Linos 25mm C-Mount lens although hopefully this will change when ET market it. This is due to the distance to the glass etc.
