There was a period in the late 80's where popular VHS format was being used to distribute a new technology for 3D presentation called Field Sequential.3D. There were many films that were transferred to VHS back then that used this better looking format as opposed to anaglyph ( red / cyan glasses) as 3F for the home weren't ready for polar twin projectors in the home such as the ones used in the movie theaters. As the VHS format began to die, companies transferred many of these to DVD and they still worked. The technology is based on the field interlaced trace scan of CRT TV's. It uses special shutter glasses, pulsed at 59.94 fields per second, a sync box, and your CRT TV.

While the DVD's are still available, and you can also find the glasses and sync box on places like ebay, few people have the CRT TV sets required to make the system work.


I have a couple of these old DVD's such as The Haunted Castle and Encounters in the Third Dimension There are about 30 titles that I know of and they are pretty cheap to buy on Amazon etc. You can also rent many of them from Netflix. Until yesterday, I have never seen these in 3D!

To view them on modern Digital TV's requires an FPR ( Film Patterned Retarder) Passive TV set such as an LG passive or Vizio Passive. First insert the DVD with Field Sequential 3D video in your computer with a DVD player and Windows Media Player 11 that is set to play DVD's from your drive. Your computer needs to be 3D ready and connected to a Passive 3D monitor. Do not put the TV in 3D mode. Leave it in 2D mode but put on your 3D glasses. Now, move the WMP playing the DVD to your passive monitor and allow the image to size naturally on your HD screen to it's native 720x486 frame size. The image will blow out to full 3D with excellent depth. The image will not be full screen but you can sit closer. You cannot resize the scale because that will destroy the 3D effect. The trick is to display the Field Sequential video in sync with the FPR coating which is at the native resolution of the monitor which is likely 1080 x 1920. If you resize the screen to 486 x 720, that will not work because now the FPR will not be in alignment with the fields in the DVD. The image will be resized to full screen but will lose it's 3D effect as the. The math just doesn't line up. Allowing the DVD frame to sit on the larger screen can line up somewhere in the middle easily because all it needs to do is find a location where the lines converge which is not difficult at all. Pretty much an automatic process.

Until now, it was thought that the display of this format was impossible unless you had a traditional CRT TV set. Now you can view the movies on your 3D passive TV.


I have been trying to work with using a set top 3D BD DVD player but so far these have not permitted proper display of the 486 x 720 image without rescaling. It may have a chance with using composite video out, not HDMI. If you want to try it, I'd suggest starting with composite video output from a regular DVD player that won't rescale. I haven't tried that yet. So far only the computer and windows Media player or the preview screen in Vegas set to Line Alternate works but WMP is easier.

While none of these movies are of Avatar 21st century quality, if you want to recover some old films that were made in 3D you now have a way to play them.

Some of those movies are fun. I have some from those days, too. I was surprised to find they played fine in 3D on my system using NVidia 3D Vision, either Stereoscopic Player or PowerDVD, and my old Optoma HD66. I haven't tried them on my newer Epson 3010, but I think NVidia's driver knows what to do with this older format, so you don't necessarily have to have a passive 3D display.

I realize this thread is 6 years old but I was interested to know if you ever cracked how to use a dvd player to play these field sequential 3d dvds on a lg FPR passive tv? And is it possible to use a vhd player on an lg FPR passive tv using their vhd discs. I was thinking of buying a vhd player but there is no point in doing so if the vhd discs can't be played on a modern tv, at least for me.

I think it would be unwise to try to play these old formats straight from disc.
No only the current 3DTVs aren't designed to recognize these old formats, but their deinterlacing filters are probably poor as well.

It would probably be a better idea to put that disc in a computer and extract the video. You'd need to find a good DVD ripping software capable of advanced tweaking to extract the odd and even fields intact (without deinterlacing), and then convert that old video into a more modern video format like side-by-side or top/bottom, and use the best OFFLINE upscaling filters you can find, because you'll be displaying very old and low resolution (640x240) images on a brand new FullHD or 4K TV... It will probably be ugly.

Passive 3D, forever !
My Full-HD dual-projector passive polarised 3D setup. (really out of date ! I need to update it some day...)

That is what I am finding with Stranger with a Gun(although this is really immersive when viewing), Moonlighter, I, the Jury, The Nebraskan, Phantom of the Rue Morgue, etc. Able to convert the old video to sbs and o/u, but even with filters the picture is very good but not great on the 77. It is fun to watch these old golden age movies in 3d though. I appreciate everyone's help in trying to get the best quality I can out of these old features.

I have a bunch of VHS tapes in this format that I would love to convert to side-by-side format at least.

Just follow the instructions above. Works really well. Your other option is to send the vhs tapes TO SOMEONE YOU TRUST and get them to do it for you. Problem is sending those valuable tapes to someone who will send them back to you!

Problem is getting the audio right. Hard to sync it at times.

Let us know if you try it. Cool to have these on dvd though to watch when you want to. I love Flesh for Frankenstein! Now that's 3d!

Wow, I never knew VHS had 3D too!

Don Landis, Thank you so much for the detailed explanation, but I'm too dumb to understand it

I also have footage that needs conversion to SBS or over/under. Does anyone know of any software that could convert this video? Or anyone who does this as a service?

Stereoscopic Player software can convert field sequential material to any number of 3-D formats on the fly, including any number of anaglyph configurations, side by side, etc. I simply connected my laptop (with DVD drive) via HDMI to my 3-D TV, and by choosing "viewing method-side by side -half" in the software and putting the TV in side by side mode, I get a decent full screen 3-D image on the set. Luckily, I've got good masters of much of this material, so it looks as good as it can. No flicker like watching this stuff on old CRT TVs.
