We uploaded some clips for testing streaming 3D. Your comments will be appreciated.
Shutter glasses supporting (Interlaced / Line-Blanking) and Media Player required.

We will intorduce a movie player to view those upto full-screen soon.

Try DivX instead, better quality and keeps the interlaced data intact, unlike wmv.

Thank you for your suggestion. We tried it before, but could not see any better compression compared to our own ways.
We will try it again to see if it any improvement is there for 3D.

The key issue is intact interlaced data, not file size. If you can't afford the bandwidth, the don't post any clips, what's the point of having broken stereo movie clips?
Try latest Divx5 and no de-interlacing activated.

First may I say nice videos, welldone!

Whilst DivX keeps the interlaced data, I have found in the past there to be colour bleed between fields.

I recommend you use MPEG-1 as the example below proves it works.

http://www.vrstandard.com/3dmovie/samples.htm

Before anyone says MPEG-1 doesn't do interlaced, I know but for line blanking it works fine. The above MPEG-1 file also works in page flipping mode with Michal Husak's stereoscopic video player V1.1 beta5.

The file can also be manipulated to other 3D formats using a combination of VirtualDub and AVISynth script (freeware) or 3DCombine etc...

The folks at http://groups.yahoo.com/group/3dtv/ will help on the latter.

Finally...
Anything that is streaming on the internet is a real turn off for me, as I have a relatively slow modem. I frequently like to view a video more than once to show to friends etc. Logging on everytime to do this just isn't practical.

We put those on our site for streaming test only, and don't want those(320x240) be used for demo purposes.

Over 15 minute long CD (640x480) will be bundled to our VRJoy package from sometime thise week. Later we will sell the CD speperate, too.

Just my opinion: Distributing interlaced video is sub-optimal. Better option is to us to use left/right or over/under format+ use some realy hi compression (DivX) ... Specialized playback software can later reproces such data into interlaced, anaglyh or even better things ...

Mr. Husak,
As a VRJoy glasses marketing company (NOT as a movie production company),
1) Anaglyph is no the quality we are tracing.
2) We have to consider the general public as the people with almost zero knowledge on computer.
Selling titles to the current shutter glasses users will be very simple, but you won't imagine that we even get tech support calls from users for even simple computer knowledge. We can no way expect those users can download any software by themself.
3) Over/Under with Sync Doubler, of course, is bit better than interlaced. Meantime, our final target is pageflip. The reason why we not include Sync Doubler on our hardware is because of the general public. Any non-expert user who set the refresh rate at 100Hz or higher at a certain resolution enjoying pageflip over internet or others..... let's guess that he starts sync doubler by mistake.... Out of Range..... It just will cause a lot of problem.

Anyway, all the Animation clips on the CD are originally formatted Over/Under. It will also display in interlaced mode automatically.

Hi Skim:

I agree that anaglyph is obsolate.

I agree that synch doubling is a mode witch is hard to adjust (need to change refresh rate e.t.c.)

I just want to say that the best method of stereo-video distrubtion is not to use interlaced format for distibution (not to fall in deinterlacing codec problems). Better solution should be to use over/under or left right ...

A software reprocesing this data on the output to anything (anything = interlaced, over under with adjustabe shift, nVidia HW page flipping, OpenGl HW page flipping, Winx3D page flipping, patterns for autostereoscopic monitors, left rigth for passive polarized projection, all existing anaglyphs method , 3D->2d conversion, anything you want) will do the rest of the job.

Yes, you will need a specialized movie player in this case. But you will get quality ...

Got it. We will let you know later this week.
Meantime, our way of compression does not have deinterlacing problem. ALso less ghosting.
