Jitter-GIF generator

This is an animated .gif generator that takes .jpg files as input.  I hope you find it useful!

A friend of mine bought a Fujifilm W1 a while ago, and has been taking very entertaining stereoscopic images with it.  The only problem with taking stereo pictures, though, is that it’s next to impossible for anyone without very special hardware to appreciate them.

Enter the “Jitter Gif”.  If you take the two images that are captured from the left lens and the right lens and put them into a fast-looping animation, you can get some sense of the space that they capture.  It’s demonstrated really well at 3erd.  While it’s possible to make such Gifs in Photoshop or a specialized tool, it’s often too much of a hassle for people to bother with – Photoshop has a serious pricetag and is total overkill if you just want to see what it will look like.

Toward that end, I have made this generator. Feed in your jpg frames and get out your gif movie.

This is an example of a jitter-Gif of the junk on my desk, although not taken with a proper stereo camera. Even so, you get a much more interesting sense of the objects in the scene! Note that you will want to shrink your pictures down to a manageable size before constructing the animation.
