I always encourage people to use their own music creations in the videos they produce, but I recognize that that is not always possible or practical. My next recommendation then is to use Creative Commons licensed music ( here are seven good sources ). This morning through Pitchanan Gaysornmas I learned about another good place to search for and find Creative Commons music, the Vimeo Music Store . The Vimeo Music Store offers more than 45,000 music tracks.
For a while now I've been using Posterous in class and in training sessions to help show teachers and students just how easy it can be to create a blog.
Viewbix is a new service for making videos interactive. Viewbix works with videos that are hosted on YouTube and it works with videos that are hosted on Facebook. I gave Viewbix a try this evening and while "interactive" might be a slight overstatement, you can definitely add some enhancements to videos. To use Viewbix you first specify the url of the video that you want to work with. Then you can add a custom "button" to your video.
