Overview
Resolution is defined before framerate speed. You define the cell resolution then the cells framerate displays video information matching that resolution.
2x resolution = 2x information framerate
1x resolution = 1x information framerate
You make may two distinct cells that are different from each other, or clone one cell so two cells are made but they are the same.
Displaying two distinct cells means you may either displaying them once or multiple times.
Displaying cloned cells means you show them multiple times.
Displaying information twice means the resolution + framerate is not equal to itself, the framerate does not match the resolution.
Parallax method
Clones the resolution on one cell, the cell framerate shows information at one times.
This means the resolution does not match the framerate: the resolution is at 2x (cloned) and the framerate of information is at 1x.
When shown as 48fps content in a 120Hz 3D TV
Left Left, Left, Left
Right, Right, Right, Right
So 4x resolution with 1x framerate of information.
Or with real stereoscopic pair shown as 48fps content in a 120Hz 3D TV
Left, Left
Right, Right
So twice the resolution of framerate of information.
3D effect
Is created by resolution at framerate speed with no artifact from resolution and framerate being different.
Simply having time sequential 3D: left left, right right, is not creating the framerate seen in time parallel 3D.
Time parallel 3D is twice the resolution and framerate of one 2d cell: resolution and framerate are the same, 2x resolution = 2x information framerate.
Until you have seen Time Parallel 3D properly you have not seen 3D effectively. Time Sequential 3D does not qualify as the same quality.
Edit. adding following replies I made to the first post for easier reading so you can understand my idea better:
When I say Resolution I'm using in context of a stereo pair of pictures: having two different pictures increases the resolution seen.
Why? Because the orientation seen in a stereo pair is from two different pictures that are pointing in the direction of what is being filmed. Two different pictures means twice the resolution.
Each picture carries it's own frame rate when considering a stereo pair. So the left side is 25 fps and the right side which is a slightly different picture is 25 fps.
(2x resolution = 2x framerate) = (left at 25fps + right at 25fps)
I know that the Time Parallel method can use multiples of a frame to fit into 120Hz TV's and still be called Time Parallel, but it's not what I call Classic 3D.
When the frame is doubled and the fps is made out of sync due to this (as described in the first post), then what happens is what cakefoo described, desynchronization.
So to fix this the left eye has: a single 25 fps shown a single time, not multiple times. Then the right eye shows 25 fps the same way, so there is no desynchronization.
This results in the 3D being more immersive.
