After a few months of tweaking the code I released today Lapseler.
Lapselser is an application that can take pictures from any QuickTime supported devices and compile them in a movie.
Because the compression library is from FFmpeg it can generate QuickTime files but also flash videos.
The motivation to work on this application is both that I am interested into time lapse since I saw Koyaanisqatsi many years ago and I am learning several interfaces of Mac OS X / cocoa right now.
Lapseler is available on my web site:
Leave me a note if you make some use of it.
The app is completely free and has no limitation, so you can use it to make cool videos for whatever purpose.
