Viewpoint. You can actually record video, audio and embed it directly into your school website or into Edmodo (and probably My Big Campus too). One thing I like is the fact that our school does not block these video streams. Since they are directly coming from CLEAR, my school doesn't block it. It saves a lot of time with the process to unblock websites for classroom use.
The program has a few options for you. First of all, you can record a video with a camera and upload it to the site. You can also record directly onto the site. There are places to make a collection of videos as well. You can also add your students to the site and have them respond and upload video.
It's something different to do in class and with so many people starting to talk about the flip, it might be a way to do it successully.
