A free, online version of Camtasia, Techsmith introduces the Jing Project. Record your screen for up to 5 minutes of video. Include sound from my microphone or headset. Use Jing to capture just a part of your screen, or the whole thing; in full video, or just a screenshot, and share it online or save it as a local video or picture.

This is an ideal application to use to show a friend how to change a setting somewhere in a program, fix their desktop or screen-saver, show someone how you install a new application…and just send them a link to your video that gets stored online automatically. No worries about uploading or hosting your pics and videos…Jing handles it all.
