I used the netpbm graphics toolkit to mass-resize the images from the native size (3072x2048) down to VGA (640x480) or HD720 (widescreen) resolutions. For the widescreen ones, I also incuded a pass to first crop the images, and that would depend on where I felt the most interesting spot was, either the top, bottom, or somewhere in the middle. Once I had images of the right size, I would run them through ffmpeg, which combines them into a video. The final pass is to simply convert it to Ogg Theora format, which I do using ffmpeg2theora. All of these are command-line utilities available in Fedora, which is a GNU/Linux operating system. For Windows, most of the pre-processing can be done through VirtualDub, which can read in a sequence of images very easily. Your comment is inspiring me to make a post about how to create time lapse images from start-to-finish, including using CHDK to capture the time-lapses in the first place. Thanks! Blazer,

Was wondering what software you used to stitch together the images and crop? They turned out awesome. Awesome timelapse vids.
