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.
