I have the Alien Adventure DVD. There is a bug in the 3D-Part of DVD!
Who had this DVD too and is there are anyone with the same Problem or with a correct version?
The Problem is, the Left Eye is one Picture to fast. So by a change of the scene you will see the new scene left and the old scene right!
Or by a fast rollercoaster move you see the rail is not a the same high!
My English is bad but i want help :-)

I know the DVD and I didn't notice any such problems.
Of course the view of one eye is ahead by 1 frame from the other view, since they are sequential.
1 frame represents 1/60th second.

The original IMAX movie has 24 frames per eye per second. The DVD has 30 frames per eye per second. So some frames are double and maybe you're right and they screwed up the sync between the two perspectives by more than one frame.

Afterall, I think it's not a big problem and there's certainly no easy solution. You would have to bring the movie to the PC, separate left and right frames and put them together again with a shifted time gap. If you can do this you are the new No.1 editor/programmer in the stereo-community.

And by the way there's certainly nothing wrong with your DVD-player, TV-set, glasses-controller and glasses. These devices are certainly not able to change the sequential order of the frames, so they are not to blame.

Hi,

Yes - I noticed that in Alien Adventure as well. The left and right images are interlaced together on all the DVDs, but in Alien Adventure the left and right frames are out of sequence. Since I watch these DVDs using 3DCombine anyway I added a function to delay one of the eyes when converting from interlaced to parallel, which fixes the problem quite nicely. There will still be a slight offset due to the telecining but it's much better.
