The team behind the screen-recording utility Camtasia have released a simplified, experimental version of the technology, packaged into a nice downloadable application for Windows and Mac called the Jing Project.
Jing makes it very easy to grab screenshots and videos straight from your PC, and then save them or share them on the Web. The coolest part of this experiment--in theory--is Jing's integration with Screencast.com, a hosting service for videos recorded off your computer. Once you've recorded a video, you can save it to your Screencast account, and from there you can get an embed code to put it in a blog or other page.
The experimental Jing is great, but oddly, the well-established Screencast.com site is the weak link in the chain. It's unattractive, and the embed codes are nearly impossible to find. On the plus side, the Screencast.com trial doesn't apply to Jing users--Jing has announced that the $6.95 monthly fee gets waived for Jing users. Still, Jing really needs a quick and easy way to upload files to more free vid-sharing sites.
FLV uploads are recommended to be in H.264, but other than that, for a clean, flexible, and almost fun way to grab pictures and onscreen videos, Jing really can't be beat.
UPDATE: Jing announced on June 18th that Screencast.com is free for Jing fans.
