STEREO video |
The old standard for stereo video was interlaced (field sequential), which involved utilizing the two fields of each NTSC frame into left and right half-frames. This allowed standard video systems to be used- though resolution of each eye is only half of normal vga (2x 320x480). NOW! With a good computer* or Blu-Ray 3D system, dual stream 3D video at up to 1080P HD resolution can be realized. *Usually L and R streams are married into a single "double-size" file and played with special stereo software. |

PASSIVE GLASSESSTUDIO 3D can now project full-color* polarized stereo video digitally. Our old system used a pair of INFOCUS LP-530 DLP projectors which put out 2000 lumens each. (We recommend DLP since LCD panels are themselves polarized, and will generally interfere with lens polarizers.)A projector stand is recommended for critical alignment of projected pairs. We use a grid image for our desktop wallpaper that helps alignment. Digital keystone correction is a great help in this regard (though some fear image degradation, we've not seen it).For more on 3D PROJECTION, click HERE.*Anaglyphs can be projected digitally as well, with a single projector (LCDs are more reliable than DLPs for accurate color for clean anaglyphs). |

We are using the SONY VAIO F 3D laptop for both viewing stereo and sending 3D to 3DTV and stereo projection systems. | ||||

3D VIDEO SOFTWAREWe have tried several software players that work quite well. STEREOSCOPIC PLAYER is shareware, and the latest version is very robust! A freeware program that is quite good is STEREO MOVIE MAKER . A more professional option from LIGHTSPEED is DEPTHQ ADOBE PREMIERE for StereoIn order to create two separate sync'd stereo video streams, Left/Right clips must be aligned and trimmed, then saved in separate Left/Right folders but with exactly the same names. All the transitions, moves and effects (along with audio) can be applied to all the Left clips (which had been moved to any empty folder) and a Left video stream created. Then the Left clips are removed from that folder and replaced with the Right clips. Another video stream is created with the exact same effects, but this is now the Right video stream.This technique can also incorporate STILL image pairs. |

The new SONY HMZ-T1 is far from perfect, but there is no question that the technology is catching up with the future. The downside is that the 45 degree field of view lenses have an extremely tight sweet spot, which both eyes have to hit or the stereo image is just not clear. But when you get it, how sweet it is! OLED 720p is beautiful, and cross-talk free, immersive HD 3D stereo now available. With built-in headphones and funky headstrap, curiously missing from this promo image. $800 sounds like a lot of money, but it's a lot cheaper than similar options that didn't view nearly as well. | ||||

Zeiss has come up with it's own HMD! It's called the CINEMIZER and it was selling for $449 at B&H. Specs say 640x480 resolution, side by side format for 3D. NO LONGER AVAILABLE |
||||
 |
The VIDEO 3D Pro is the best HMD we've seen. They accept interlaced NTSC (or PAL) video, and sizes them up to the 800x600 pixel per eye resolution- which is surprisingly good. Built-in headphones, too.
NO LONGER AVAILABLE |

The $500 VUZIX Wrap1200 looks good, and seems a lot more comfortable to wear than the SONY HMZ T-1... but the resolution is only 852x480 per eye. We haven't seen them- says it supports side by side 3D (full or half?) and, oddly, 3 formats of anaglyph (!?). | ||||
 |
The VUZIX AV920 (formerly ICUITI) is a lower cost solution, they call it "iWear". Picture looks quite good for dual 640x480, with earbud type earphones. Interface powered by 2 AA batteries or adapter... accepts composite video or vga signal. Our biggest complaint concerns design- front heavy, and hinges that move vertically, they don't sit comfortably on the nose. A strap would help.
NO LONGER AVAILABLE |

 |
The eMagin 3DVISOR E800 sure looks good, but we could not get it to run on our computer... and their tech support was no help.
NO LONGER AVAILABLE |

 |
Newest I-VISOR FX601 is now called FMD for Face Mounted Display!) works with 800x600 OLED panels, and comes in various configurations to work with PC, video or both. We've not tested yet. | ||||
 |
The older I-VISOR DH-4400VPD (newer version called CY-VISOR) handles video as well as PC input- both interlaced and dual stream (of course, dual stream looks a lot better!)
NOTE: Lists as limited stock, no longer manufactured. |

LIQUID CRYSTAL SHUTTERShutter glasses require page-flipped stereo... some video cards from nVidia offer stereo drivers, and some feature mini-din ports for the specific wireless emitters (or wired glasses). |
|||||
|---|---|---|---|---|---|
 |
NVidia has a kit for Windows 7 (and Vista) which of course runs on specific nVidia graphics cards without the need of mini-din port (usb emitter comes with kit). It's made to run with "3D Ready" monitors, which run at 120hz or better. We like this system, as it's relatively easy to setup, but the 3D mode tends to take over the entire video system (one cannot actually work in 3D mode, from our experience- but slide shows, 3d movies and games look very good, with little cross talk). | ||||
 |
CrystalEYES from RealD/Stereographics was the state of the art (although expensive @ $600 each plus emitter) shutter glass setup for the PC or Mac. Their current model is the CrystalEyes 4s. |
||||
 |
The NUVISION 60 GX Wireless Shutterglasses, were a less expensive alternative to CrystalEyes! (about $350 plus emitter) | ||||
 |
Razor 3D offers a very inexpensive ($29) wired system for viewing interlaced stereovideo on your CRT, which no one has anymore. Be advised, however, that the slower refresh rate of a TV set causes flicker which most people find objectionable. Edimensional offers wireless PC glasses with a short range (10') ($99.95). |
