CamStudio is free and open source screencasting software that saves the video as AVI files, though a Flash converter is included.

VoiceWalker is a transcriber's tool, designed to help you transcribe audio or video recordings. VoiceWalker lets you play back the sound in a controlled way, with the benefit of being able to systematically step (or "walk") through a recording, repeating short segments for a specified number of repetitions, then moving on to the next segment. The segments overlap, so that the transcriber does not become disoriented. VoiceWalker assumes that you have digitized your recordings as computer files to work with them more easily (for information on how to digitize, see the VoiceWalker manual). VoiceWalker is free, available for Windows only.
