Convert MOVs to Gif super easy
Animated Gifs are all the rage, and there's no better place to create and touch up GIfs than ezgif.com. It's the one stop shop for all your basic GIF editing.
I like to use their optimize feature to better compress GIF files that have been created using different applications.

Sample GIF Images
Here's a couple of images that I converted from H.264 to GIF:
Boston's MBTA Commuter Rail. Using ezgif.com I was able to convert the original 2.9 MB MOV file to the 732 K GIF
This Movie was 1.8 MB, but using ezgif.com I was able to get it down to 652k.
