are you sure this wasn't because there was an error in your config file (like wrong size, etc.)? i've had mpeg_encode segfault on me a few times, but usually when i gave it incorrect information to begin with. attached is a really simple example config that i use as a template for all the movies that i make. also, it might be because of some wierd non-standard format inside the jpeg or something (though i've never seen this). if nothing else works, i'd try converting the image to another format like ppm (imagemagick is sweet for this) and trying to encode from that. --sean
