Ok, maybe some software is required, but not the kind you’re probably thinking. ScreenCastle lets you record a screencast via Java through your browser.
Simply go to the website, click on the record button and a popup will ask you for the screen area you wish to capture. A black bar will float at the top of your screen, extending recording controls. It will even capture audio via your microphone.
ScreenCastle will also automatically host your screencast so you can share them easily with others. All of this for free. If you want to capture your screen with ease, and at no additional cost, check out ScreenCastle.
