3-D filmmaking with Super-8

[56films]

does anyone know how to shoot 3-D.
i want to shoot a 3-D horror movie. I know of the two cameras side by side thing. but i was wondering if there was c-mount lense that could take care of this. and also is it anaglyph or polarized. or are there some plug ins for adobe premiere or final cut. ANY tips would be greatly appreciated
thanks!

No special lenses that I know of, though normal to slight telephoto look the nicest to me. Personal preference, perhaps, but I find wide angle pushes all the detail too far away. Half the fun is inspecting all the nooks and crannies of the scene.

Premier already has a BLUE/RED filter for 3D built in. Look for it, it's there.

For some anaglyph information and other 3D stuff, check out this guy's site. He's great.

PS: How do you plan to keep your cameras synchronized? Crystal?

Just curious....

thanks roger,
yeah, sync was gonna be another problem.
i thought about getting two of the exact same camera. but even then they'll be falling in and out of sync i bet.

or dare i say using two DV cameras instead of super-8?

hey in premiere is it the "color offset" filter?

thanks again,

will

I wonder if there could be a way to do it with a double super 8 camera.

That would be ideal. I have helped build a 3D rig using a 16mm camera where the images were side by side and reduced. Basically, the end result was the size of two super 8 frames, side by side with a LOT of black above and below. Using Double Super 8 would be better use of the film volume since you could put the images side by side and just never split the film after processing. However, I know of no Double Super 8 projectors, so it looks like you would have to use a couple of Eumig double band projectors with the film spit between the two.

Crystal synch will work to a degree but the images could be out of phase, meaning that one camera could have its shutter open while the other has its shutter closed. They would maintain that relationship as long as they were running, but the phase difference can sometimes look weird, from what I've seen.

All video cameras will run in perfect synch, so the miniDV would work just great. Viewing is another story, unfortunately. There are some low resolution "I-Glasses" made for 3D viewing but they depend on using the interlacing of the video to carry the dual images, which cuts the resolution down even more. Two LCD video projectors with polarizers and a reflex screen work perfectly, but a little pricey. Plus, you need a way to start the video sources at exactly the same time. You could probably find a used video edit controller that would do the trick and would be accurate to within a frame, which is plenty close enough, since you'd be working in video and not film.

No the Premeir filter is pretty much marked "3D" or something obvious like that. I don't have my system fired up or I would go look for it. I do know it is a render only filter. Now the red/blue thing can work just great if you get the filtration and color adjustment on the TV set right. I saw a laser disk of "Creature from the Black Lagoon" and the 3D was perfect.

Good luck!

Canon does sell a 3D lens for the XL1/XL1S. The cam is about 3000-4500. Depends if used or the newer model (XL1S). The lens itself is about $4000 (i might be off). That would bring your equipment cost to around $9000. Many here do not like DV. I do. Amer Cinematog did test the lens with a DP a couple of issues back. YOu may want to check it out. Either way, I am sure many of us would like to read your production notes on this one (website?).

Good luck and keep us posted.

i'm not very experienced in video, but it seems like unless you had a proper genlock/tbc/whatever/and so on setup, video cameras would have basically the same phase problem. slightly less obvious due to the 100% duty cycle, but still...

Hi, Mattias!

Yes this is true about the phase issue. However, my experience has been that the most they would be off would be no more than a 60th of a second (for NTSC) or the equivelant of one field. That is so negligable that the eye doesn't perceive the effect, though it no doubt can be there.

When I was speaking about "perfect synch" I mean that the two cameras would not require special controllers to keep their running speed in synch with each other, even if the the interlacing of the two was slightly out of phase. If they were half a video frame off, they would maintain that relationship and the human eye wouldn't really notice it due to the 100% duty cycle, as you pointed out. It really looks very "live"; more so than film in 3D.

As I pointed out, the "I-Glasses" Virtual Reality goggles use interlacing to carry both the left and right image by sequencing the two images and splitting them up. Therefore, the left and right images are always out phase with each other by a 60th of a second, but it still looks fine due to the higher frame rate of video. Film shot at 24 fps that is out of phase can sometimes look weird. Not always, but on fast action there can be a perceptable "lag".

The other day, I found a web page that explains how to build your own 3D system for shooting Super8, but I don't remember the adress. I'm looking for now... Stay tuned
