  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

The All 3D-Stereo Thread

Just a quick jump-in. inexpensive single camera approaches.

1. simple mirrors in front of anamorphic lens make two side by side (2K) images that can be left together for post.

2. synchronized rotating mirror to create alternate left/right views. Again treated as single video in post.

3. Shoot at two side by side convex mirrors

After post, use convolution or whatever to prepare for viewing.

additional viewing methods include cross viewing with two monitors (used for training surgeons using stereo microscopes), over under (my patent 4,709,263,) and various others.
 
If you're shooting with two cameras, or two view points, and you're trying to avoid having an external trick to experience the 3d.. why not just alternate view points every frame?

In FCP, overlay both view points over each other and slice and dice each other frame... so if track A is over track B... every other frame would alternate, A, B, A, B, A, B etc.

This would flicker the viewpoint and achieve the "I'm seeing from both viewpoints" type of effect.. no?

Totally wrong?
 
Single Camera Stereo

I did some tests recording to the internal Digital tape in a camcorder and direct to the video input on a digitizer board on a computer, and going direct into the computer is much better than taping in the camera, at least with the stuff I was testing...

Keep in mind that HDV videotap format is only 1440 pixels horizontally (using non-square pixels.)

Even though your camera has 1920 in the sensor, it must be reduced to fit the tape.

When you run the firewire output, you (should) get the full resolution.

There are adapters to put two images on a single sensor, generally a series of mirrors in front of the lens, but matched lenses and two cameras sure seems to be the way to go today.

Back in my 3D days, i used an adapter from MARKS POLARIZED CORP. to produce a 3-D short entitled "Summer Day." The adapter was HUGE, and sat in front of the camera's lens. I shot with a SONY BETACAM, although the adapter was intended for use with a 35MM camera.

In 35MM use, the adapter created 2 two-perf images. It was used in the production of "Andy Warhol's Frankenstein" and possibly others. When used with the betacam, I set it up for two images on the video screen.

This system was known in the industry as "OVER AND UNDER" and was much more complicated optically than traditional stereo images, which were "SIDE BY SIDE"

The advantage of over and under was that it produced a nice wide image. Chris Condon's STEREOVISION system used side by side images on the film, but incorporated an anamorphic lens, so that the side by side images still had a wider aspect ratio. This system was use for the soft core movie "The Stewardesses." MOST films were optically printed into the over and under format for projection.

I found this page of information about the film formats.

I hope you find this helpful.
 
urgently seeking parallel mount or 3D rig

urgently seeking parallel mount or 3D rig

We are shooting a 3D test trailer next week. (April 14- 16)
We have been in pre-production for weeks, securing cameras, prime lens, equipment, locations and and and

We already have 2 RED cameras, equipment and were going to be using
the P S Technik rig http://www.pstechnik.de/en/3d-rig.php
we just lost our rig. (our supplier lost their financing, and we lost the rig)

As a backup we are thinking of shooting with dual cameras, using a parallel
mount.....

does anyone have a dual mount that can support the two RED camera?
or information about dual mounts / designs
if so please contact

jinapanebianco@gmail.com

thanks
Jina
 
FYI: Mammoth HD like the rest of you reading this thread - see a huge future for 3D (especially with the new tools - software/hardware that are coming out...) SO......

Mammoth HD Footage Library is in the early stages of building a new 3D/steroscope footage library/gallery

www.mammothhd.com/3D/

We will be looking for 3D shooters/producers for content - representation. Any questions on the MHD/3D Library contact me directly here or thru the MHD site.....
