New 3D projection system that works with existing 35mm film projectors

[Terry Delahunt]

I wonder if this will slow down the roll out of Digital Projectors.

"Technicolor Business Group, today announced a high-quality, affordable 3D solution that works with existing 35mm projectors."

Over-Under, or ana-side-by-side?

Over-Under, or ana-side-by-side?

Does anyone know if this is an Over-Under Techniscope conversion on the print for 2.35:1 with two Techniscope size frames, or if it is Anamorphic Size by Side giving a less wide anamorphic image?

Over under with a "flat" lens should give better results, Anamorphic side by side does not look good because the lens and film limit the resolution too much so you get "cardboarding" of the 3D images.

This is the "over-under", which incidentally is similar to what Sony does digitally with its "bastard RealD" system on the 4K SXRD projector (2x2K).

Out of frame prevention?

Out of frame prevention?

I was wondering if anyone knows how Technicolor plans to prevent the over-under film from getting two perfs out of sync, that is if the "projectionist" turns the frame knob on the projector until he sees two images on the screen you can get two ways for the images to line up, one the images are stereoscopic the other pseudo-stereoscopic.

It may not be obvious to the "projectionist" that the projector is not framed for stereoscopic viewing since people with poor 3D vision may not be able to tell stereoscopic from pseudo-stereoscopic viewing.

That being the case, there may be a 50/50% chance of seeing the film projected the right way.

I am sure they have a test film to start with, but since cineplex cannot even focus the projector much of the time, I wonder what makes Technicolor think the same person from the candy counter can align a 3D movie right?

Perhaps there are numbered frames at the beginning of a reel that the projectionist can line up. Or frames split in half that cause obvious flicker. Shouldn't be too difficult to make something obvious should it? Then again, as you say many of the theatres don't go out of there way to employ pro's to do these things. Whatever they do there will always be someone, somewhere, who get's it wrong (Or even does it on purpose for shits and giggles).

The Sony/RealD adapts a Dual lens System adapter which mounts to the SXRD Projector, and all you need is a SIlver screen to get 3D, and I will not really call it Bastard, as it is quite a serious system integration by the Two world Leaders , one in Projectors and the other in 3D.

But more is to come as far s 3D goes, and the pressure is on by all major Studios.

I meant "bastard" because it is different from the real RealD technology used on the majority of cinema projectors (DLP), which doesn't work on the Sony SXRD panels, so they had to invent a workaround for the Sony.

On DLP RealD you don't need to invest in an extra specialized dual lens system but can use the existing lens and a polarizing LCD screen in front of the lens.

In Dolby3D and XpanD 3D DLP you can in addition also drop the cost of the polarizing LCD and the silverscreen.

4K DLP will be able to do 4K in 3D.
Sony 4K won't do 3D in 4K without inventing a new type of 3D system.
