Left or right eye first? According to this document (http://lists.gnu.org/archive/html/bi...z6rW7jUrgI.pdf) 3D Input Format Requirements for DLP® Projectors using the new
DDP4421/DDP4422 System Controller ASIC , it is said that:

"The last active line in each stereo pair (left and right frames) shall alternate between two
frames of green (G=255, R=0, B=0) and two frames of magenta (G=0, R=255, B=255).
The left eye frame must always be transmitted first in each stereo pair."

The projector has a setting to set the sequence in reversed order, just in case of, and I found in the manual of my 3D glasses that there is a button that has the same function. I could test this if I had a 2 30 second files, one with left first, the other with right first.

Frame rate? Not sure. When looking at "tal.aloni" his BigBuckBunny-720p-3D.mp4 I see the following information in my player:

As a last note I can tell that my glasses have a refresh rate that supports 96Hz, 100Hz, 120Hz as well as 144Hz . From what I understand 144Hz is the new and better standard. Note sure where this fits in when discussing adding frame sequential packing. But I just give this as additional information for you.

Maybe "tal.aloni" has more usefull information in the thread I referred to?
