Use with document camera, free annotation software, etc.
Works on PCs or Macs. Free (Jing) or $14.95 per year (JingPro).
You can record up to 5 minute mathcasts with Jing or JingPro and then easily share them through free 2 GB Screencast.com (also from TechSmith) account or in many other ways (embedded in InterWrite Workspace notebooks, SMART Notebooks, etc.).
Jing (free) will produce only to .swf (Flash) output format. Camtasia Studio can now import these as well as .mp4 files created by JingPro.
Jing or JingPro allow you choose whether to copy a link to your screencast or the embed code to the clipboard. The latter makes it incredibly easy to create a mathcast or screencast and embed it in your blog, wiki, etc..
Although it is possible to create mathcasts with software like Microsoft Word, specialized math software, or other tools that generate text or images most of us have found annotation software like InterWrite Workspace, Smart Notebook software, Blade NotateIt, or Microsoft OneNote to be extremely helpful.
Although you can create mathcasts with only a mouse & keyboard for input there are several types of graphics input devices like graphics tablets, Tablet PCs, and electronic whiteboards which will help you create mathcasts much more easily than with a mouse alone.
Screen recording and production software is required for capturing writing, typing of text, or animations and producing them in a format for the web, CDs, or portable devices like the video iPod, Pocket PC, Palm, or Sony PSP.
