The Latest Gear Behind 3D Movie Making
Posted by Adrian Covert at 10:30 AM on August 24, 2008
DLP recently teamed up with former LucasFilms effects studios Kerner Optical and Tippett Studios to work on a stereoscopic 3D Trailer for their cinema projectors. Pushing this style of filmmaking (kinda like the 3D attractions at theme parks) forward was something they were all excited about, and they took me around Kerner Optical's facility and showed me the latest camera gear they used to make the 3D trailer.
Seeing the camera setup in person is pretty awesome. It consists of two cameras — one facing straight forward in a horizontal orientation, and one facing straight down, in a vertical position. Between them sits a mirror, angled at roughly 45 degrees, that acts as a beam splitter, directing the image to the vertically facing camera and helping to create the 3D effect.

While the vertical camera remains stationary, the horizontal camera slides from left to right. In doing so, the intensity of the 3D effect varies according to position as the pictures from the two cameras phase in and out. Once the camera has done its job, its up to the viewing apparatus to carry out the rest of the magic.
Kerner Optical uses special LCD monitors with the ability to display 3D images with the help of polarised glasses. Many rear-projection DLP televisions actually do the same thing, but a lack of content support has kept the technology obscured from most owners.

Many people in the industry are pushing for 3D filmmaking to take off, as they think it's the next big technical innovation in movie production. Personally, I'm all for it, because it really is fun to watch, but until the industry finds a way to get the same effect without glasses , I'm not sure mainstream acceptance will be easy.

scarbrtj - not true at all, I have a 3d monitor at home, I won't mention the brand since that can be construed as spam, but anhoy it costs 599$. UT3 + stereo3d + 5.1sound = Da bomb!

The cynic in me says studios want 3D because 3D is difficult to recreate at home... it's a tech that might get people back into theatres en masse.

@scarbrtj: I'm convinced that studios want 3D because people think that 3D will make shitty movies good, just like the 3D computer animation craze that resulted in a lot of 2D animators getting the boot.

Indeed you do need glasses to view polarized 3D content.
For home viewing, the easiest method at the moment is to use LCD Shutterglasses, which flip back an forth between the left and right images while covering the other eye. This happens so fast no flicker is perceivable. It works with all CRTs and some back-projection based tvs like DLP, however flat panels like Plasma are out because they're refresh rates can't be synchronized with the glasses properly. I have a shutterglasses setup at home, it cost me $75 and works perfectly.
For theatrical presentation, there are two major brands out there at the moment. RealD, which is the most popular, uses a combination of time-based and polarization based stereo technologies to product the 3D effect. Dolby also has its own system, which is anaglyph (color based, like the classic Red/Blue glasses) but instead of using brightly colored filters it uses colorless filters that seperate light into primary colors. Both technologies are digital and are about equal in quality (though Dolby's should have less light loss since they aren't using polarization). Both of these are proprietary however and wont be seen at home any time soon.
If one were so inclined, however, it's fairly easy to build your own 3D home theater. All you need is two projectors, some polarizing filters and glasses, and a special silvered screen (regular projection screens dont reflect polarized light properly). All of it can be run of a laptop, and the quality (depending on the projectors of course) is comparable to what you would see in a theater, only on a smaller scale.
Alternatively one could also use one projector and shutterglasses, though not all projectors are 3D capable. Many are though which makes this a simpler option.
There are also several 3D monitors out there, mostly aimed at the gaming market. Some use polarized glasses, like the one seen in the article. Also out there however are monitors featuring Autostereoscopic technology- meaning you don't need any glasses at all. So far though no one has been able to scale the technology up to a full theater, with all the different viewing angles being a bit problem.
The issue at the moment with 3D everywhere is content- there is a limited amount of 3D content being released to theaters, with many more in the pipeline for the next few years. There's basically nothing released on home video however- mostly some old 50s and 60s B movies and some IMAX 3D movies that have been released.
What you really want in a released is HQFS (High Quality Field Sequential) format, which folds the left and right video feeds into one interlaced video feed. This can then be digitally split and presented using whatever format you want. Dimension is the only studio that's actually released DVDs in that format- Spy Kids 3D and Shark Boy and Lava Girl. They also released the movies in Anaglyph format of course, with the Red Blue glasses.
Disney just released they're popular Hannah Montana Miley Cyrus Best of Both World's Concert film on DVD, including the 3D version, however it's anaglyph only. Using editing software it will probably be possible to seperate the Red/Blue anaglyph feed into two seperate feeds, but the quality will never be quite as good as if it was presented in interlaced format to begin with.

If Hollywood would tell a story that was worth a damn, shadow puppets would be a sufficient medium. In the meantime, they're chasing after some magic tech that will make their latest worthless maga-budget remake watchable somehow.

whenever I watch 3d movies it constantly flips between being in 3d an being all blurry- I think my eyes focus and defocus too often involuntarily. I think that is why I have never seen a magic eye poster either, they are just a bunch of fractals to me.

I don't really like it. There's no way watching a bunch movies like that can be good for your eyes. I think 3D movies are a gimmick and belong in theme parks and nowhere else. Besides, it's just another way for theaters to bump up the cost for ticket prices. ($10.50 to watch Beowulf in 3D?)

@dingus: I feel you, I have mild amblyopia so while my depth perception isn't totally shot, it still isn't great, and it makes 3d films annoying to watch. I, for one, hope that this technology never makes it mainstream. Or if it does, maybe they will come out with a revolutionary procedure to fix lazy-eye.

@scarbrtj:
yup wrong, its easy. dlp or other displays just need a lcd shutter glasses and 3d content for 3d. its not that technically hard if you get all 3 pieces together. its just a matter of whether that niche market can support itself and have enough media releases to justify its existence. and no, its not hard on your eyes. the lcd shutter glasses totally isolate each frame for each eye making the experience even better.

@FrankenPC:
For 3D you want to have a large depth of field, the larger Red sensor would be a detriment being you would need to stop it down to get desired DOF. In fact, for many applications a shallow DOF is undesired and the 3CCD approach is more beneficial. For indie film makers that want to recreate analog film type looks the Red is great, but its getting tiresome and silly hearing how the Red should be used for every application under the sun.

Stereoscopic is not 3D. End of story.
And having to wear special glasses to watch movies is a ridiculous gimmick that surfaces every 10 years and then (thankfully) dies back down.

Hmmm, it's interesting. I've seen this kind of 3D cam. It's really big and bulky and requires about 3 people just to operate one of these cameras, and also can't be put onto a crane/jib. They used one of this kind of camera for the Hannah Montana Best of Both Worlds Concert DVD. But most of them were another type.
Yes, another type!
This type used the same principle as your eyes and had both of the lenses/cameras side by side. Just as your eyes sit side beside and create that depth of field & 3D effect that you lose whenever you close one of your eyes. That camera looked a lot more practical. It was also used with dollies and cranes and steady cams. (they had a pretty large work force just to put it all on). Tons of fun.
I was on that tour as part of the regular tour camera crew, so it was really cool to see those cameras in action.

Funny you guys should cover this at this moment. I just wrote a blog post on why I think 3D is going to be successful this time around. It's a factor of better content, reasonable economics, and better tools for film makers. Check out the post:

@FrankenPC:
Er, no, a larger sensor will have a shallower DOF. Which is the entire point of the Red camera; it'll give you the 'bokeh' 35mm film-like effect unlike 3CCD sensors. The only way to get a larger DOF in the Red is by using a smaller aperture, but a smaller sensor has inherently larger DOF throughout the entire aperture range. The 3 sensor CCD approach is much more desirable for capturing scenes with large DOF compared to the large one sensor approach; which is why companies are still shelling out ten times more then Red for these cameras. Again, different applications.

@rainsfather: That's an awfully broad statement. Most of the creativity has been sucked out of Hollywood movies by the money guys and the audience. The money guys cause they're afraid to try something new and creative. The audience because they won't pay to see something if they don't know exactly what they're getting by watching the trailer.
Many directors would love to do something new and creative and many are. In fact, most of the folks involved in filmmaking are artists and act like artists. Also, a director may not be wholly responsible for what you see on the screen, the director of photography and the editor have some input there.
As for 3D, I've never liked it. Maybe it's because I wear glasses, but the 3D effect is always just a little bit off. I can only imagine it's because the 3D glasses are not in the optimal focus point for my eyes because they're either in front of or behind my regular glasses.

@rsquared: Your disbelief of 3d could be due to the distance between your eyes being different to the distance between the cameras used to film.
