I just got a Slideshow Pro newsletter announcing Slideshow Pro for Lightroom version 1.4.6. This version introduces a significant new feature: Ken Burns Panning. Slideshow Pro calls it Pan and Zoom. I updated my version of Slideshow Pro and changed my slide show for our rental property to use Ken Burns panning. It took just a few minutes to set the new Pan/Zoom parameters in Lightroom and rewrite the slide show to my site. I've decided to not crop as tight in the future when creating stills for this kind of slide show.
My main reason for bringing this up is that I get a bunch of questions and discussion about which slide show engine to use in general and with Lightroom in particular. Because previous versions of Slideshow Pro didn't have panning you had to use Monoslideshow if you wanted to get that video effect. With the addition of panning in this version Slideshow Pro has pretty much everything you could want or need in a slide show engine: Automatic operation, music, Ken Burns panning, display of real video clips and complete control over almost every aspect of the look of the slide show attributes. I think Slideshow Pro is now the only slide show engine you'll ever need. I now kicks ass!
It's worth repeating that 90% of the world considers Ken Burns panning over still shots as video. Tourfactory goes so far as to advertise Ken Burns panning as a "video tour". This is, of course, not video, but it's hard to tell the difference. The way to tell the difference is, this looks better than most video because you can easily take out barrel distortion, straighten the walls.
