[ale] Special effects used while creating a slide show

[ale_nospam at fayettedigital.com (Jim Lynch)]

My wife received a link to a video that showed a series of still photos 
as a video. A slide show, but with an interesting twist.  The slides had 
motion, in that there was panning and zooming so it wasn't just a static 
display for however many seconds the still was displayed.  The zooming 
looked to be the same for each photo, going from 1:1 to 1.4:1 perhaps.  
The panning was different, sometimes moving left and down, sometimes 
right and up, sometimes just left or right, etc. 

So I was wondering if anyone knew of Linux software to accomplish the 
same.  I've produced video slide shows before but they've been static.  
This effect was a nice feature and I'd like do the same if I could.

When panning it panned across the photo on a black background from a 
distance that showed the background on one or more edges.

Any ideas?  I suppose I could write a script to run convert on an image 
and create a series of images to turn into a video.
