OT: Experimenting with 3D

Well I don't want to say I am that far with experimenting but have made some

First my question: does anyone know of a device that will take a 120fps video
from BD and separate it to 2 60fps projectors with HDMI inputs?
(Frame sequential)

The system is patterned after StereoBright
using a pair of modified computer cables.
(The powerpoint explains green signal that needs to be swapped)

Dual video card and two video files generated from a simple Blender

Link to retardation film and glasses

My goal is to:
merge frames in Vegas to one file
replace the linear filter plates with circular
use HD DLPs instead of cheapo presentation LCD
use REAL 3D glasses (since we pay for them each time at theater)
Produce standard file that can be played on any 3D tv such as
3D DLP or Samsung 3D LCD TV.

EDIT: Clarification - Looking for a device that will take HDMI 1.4 3D and

Not sure about the 120 fps to 2 X 60 fps conversion, but I use Neo HD for my 3D needs. You render left and right avis and then mux them into a single avi. You can then select different modes of playback ,e.g. interlaced, side-by-side, anaglyph, etc.

Also makes it easy to edit these 3D files in Vegas. Do all your editing and then select Cineform left only to render left and then re-render using Cineform right only. Then re-mux them together again.

Thanks Xander for responding.

I am still learning about FHD3D and HDMI 1.4 standards.
The interlaced mode you mentioned I assume is the "field alternative".

I may have misstated the 120fps instead of 120 views per second if using
the stutter glasses for the 3D Samsung or DLP devices.
I guess all Blueray Discs are 24fps but have the two angles so the decoding.
device needs to route the correct 2D frame info to the appropriate projector.

Correction: ReadD uses side-by-side along with circular polarized light

Just thought update some info.
