jing
Jing is a cross-platform application for capturing video and images from the user's desktop.
If you’re wondering, “How in the world am I ever going to use this thing called ‘Jing’?” then here’s an explanation from Tony Dunckel, the Jing Product (err, Project) Manager:
“Think of Jing as a supplement to all your chat discussions, email threads, forum posts and blog entries. It sits nicely on your desktop, ready to capture and share your stuff at a moment’s notice. Simply select an area of your screen, capture it as an image or record it as a video, and then click Share. Jing conveniently places a URL to your content on your clipboard ready for you to paste the URL into any of your conversations.”
“Your content is hosted on Screencast.com, for which we are providing a complimentary account to all participants during this project. Users have 200MB of space for storing screenshots and screencasts and 1 GB of bandwidth that renews monthly. The Screencast.com account will remain available to you for the duration of the project.”
