Create and store movies on the web - Jing

From the Jing Blog:

Here's some things to keep in mind when recording videos with Jing:

• Jing records to the SWF format at 10 FPS and has its own built-in play controls. SWF is a lossless format, so a large selection area means a larger file.
• Jing records its audio from your microphone, not the system sound you hear from your speakers.
• There is a 5 minute limit for recording video. The timer on the record panel counts down from 60 seconds after 4 minutes have elapsed, so you know exactly how much time you have left.
• Keep your audience in mind. The shorter the recording, the smaller the download.
  Don't worry about making a perfect recording. Just think of it as sending a video voicemail.
