At New Horizons, I saw a demo of Animoto, a site that allows you to make free 30-second videos. (You can also buy an account, which allows you to make longer videos.) It's really neat--you just upload pictures (or use pictures they store on the site), select music (again, upload your own or use theirs), and then give it a name, and the site adds all the effects.
The ELI Student Services Staff just had a retreat a couple of weeks ago. Here's a video I made using Animoto and some of the pictures from the retreat.
Still haven't figured out how to add text on top of pictures--maybe one has to do that using photoshop or some other photoediting service before uploading the pictures. Anyway, it's fun to play with for personal use (the presenter showed a little video of him visiting his grandkids), or for teaching (I was thinking about making a little welcome video for the new ELI course I'm developing). You can see some cool things educators have done with the expanded version if you visit this part of the site (check out the "We the People" video or the case studies at the bottom. I think the "function notation" one is great).
Try it out and post your video links in the comments!
