Motion Blur

Hi,
I cannot reach a good resut when I export my OpenGL animation (which really
are several still images) to a QT movie with motion blur. My OpenGL
animation runs at 60 FPS, while I export it to a QT movie at 30 FPS.
So basically, I take the even frames (2nd, 4th, 6th...) with 50% alpha, and
I add them to the odd frames (1st, 3rd, 5th...) which I leave 100% alpha. SO
here I sign QT1 as the QT frame 1, and gl1 the openGL frame 1.

    QT1: gl1 at 100% + gl2 at 50%
    QT2: gl3 at 100% + gl4 at 50%
    QT3: gl5 at 100% + gl6 at 50%
    ... and so forth

But the result is not good. Even if the motion blur is visible, I still see
the resulting whole image half unfocused and a little bit with a strobo
effect. Wha can I do to make it better?

Best Regards
