Camera/Zoom shots don't "translate" properly from Photostory to MPEG-4

Hi, I am working on a slideshow in Photostory 2014 Deluxe. Most of the photos in the montage have some type of panning / zooming in or out to keep the flow of photos interesting. Problem is, while these effects play fine within Photostory, when I export the slideshow to a portable format (an MPEG-4 file in HD), some of the zoom effects work as intended, but a few of them zoom on the wrong part of the photo - although they zoom correctly in Photostory. For instance, on a photo of someone's portrait the effect will properly zoom on the subject's face (as I intended), but during playback of the same slideshow as an MPEG-4 file, it zooms on his belly instead, cutting off his head from the frame entirely.

Can't figure out how to fix this. The issue is sporadic throughout the slideshow (about 11 minutes long) and only affects certain photos, not all of them. Most actually zoom fine and as expected.

If the project settings are not the same as the exported format you can get positional shifts and the software should (IIRC) warn you of this when the export settings are different from the projec settings.

For instance, if the project is set to 720 * 576 16:9 and you export to 1920 * 1080 16:9 ( or vica versa) then you can get positional shifting.

Taking standard PAL DVD and HD as an example, if you do the maths you will see that 720 * 576 does not scale to 1920 * 1080.

If PAL widescreen DVD used square pixels the image would be 720 * 405 to be the correct 16:9 ratio so to fill the 576 pixels height the pixels are stretched to be rectangular and it is this that can cause the positional shift.

. . . . The issue is sporadic throughout the slideshow (about 11 minutes long) and only affects certain photos . . .

Are the affected photos from a different source or have they been cropped or adjusted in size?
