I've been working on a project with a number of video files. As expected, the file size for the .story file is quite big (600+MB). But what I'm finding odd is that if I delete the slides with the video and "Save As" to a new .story file, the file size doesn't get any smaller. And if I use the "Change Video" option to swap video files like-for-like, the .story file size increases as if I'd added a new video. Anyone else experiencing this?
