Complicated Photo To Movie nightmare

I don't know how many of you have used Photo To Movie, but I've used it a lot and love it, but I just hit a wall mixing it with footage shot on the EX1. Here's what happened:

I shot footage wit the EX1 in 1080p 24p and put it on a timeline in FCP (same settings). I edited together a number of pictures using Photo To Movie on the same timeline. I got the pictures as I wanted them and then exported the whole sequence as a movie using the following steps:

Make Movie
Movie Format QT
Movie Settings 1080p

Then I went into Options and and Settings and selected XDCAM EX 1080p24
Then I went to Size and selected HD 1920 X 1080.

I then imported the movie into FCP. It worked perfectly (except for one off thing the movie would come out twice as long as I wanted with the second half of the clip black which I would then trim) It would play back the clip on my timeline without needing to be rendered because it matched the settings of my sequence.

However, when I would export the clip either through QT Conversion or as a QT movie, the resulting movie would be out of sync and often jittery and unusable.

Am I doing something wrong or is Photo To Movie not yet working with the 1080p 24p format?

The way we see motion

Bill, the jitter or stutter is because the frame frequency (24 fps) is not high enough for the human eye to resolve the pic's movement into a smooth one.
Two options:

Export a movie with a higher frame frequency (60i) and down convert thereafter to 24p
or use a filter like "motion blur" from or a combination of both.

No mistake on your site, just the way how we see motion and what our brain needs in still images per second to assume to see motion.
