I get the same problem - but only with some picture collections, not others. The error I get is "x264enc5.exe has stopped working". It would be nice if the program could display something more helpful, to indicate the nature of the problem e.g. maybe it doesn't like a particular image file, in which case it would be helpful to know which one. Or maybe the size of the picture collection is too large (mine typically contain 200 images with a total folder size of around 600 MB) - but other collections of similar size work fine. All images are JPG. I add no soundtrack, display each image for 10 seconds, with a 0.5 second crossfade, saving to AVI format. Pretty simple, so what could go wrong? Well, something does!
