Well, since the QuickTime files have some issues when shared away from their player, it is nice to know that Jing is free and easy to use and share. I found another free site called FreeScreencast.com that offers the same advantages. It only works on the PC platform, but I thought I'd share it anyway.
Here's the LINK.
I was able to get my .mov file to work, however, by converting the file on one of my favorite sites: Zamzar. Zamzar offers free file converting, which can come in handy. Junp through a few hoops and Zamzar will email the converted file to you or you can sign up and store your converted files on their site. I have used this for converting YouTube videos so I could play them in class using the player of my choice. You just need the URL for the video and you're good to go. Check it out!
