Resubmitting this, simply as this software has solved a lot of problems. Screencasting is an old problem, I've found this really useful in solving it: Giving colleagues a walk-through, to recording my workflow for the day to share with others for a full-blown training session (indeed, recording classroom/group training). Just by pressing Space+PrtSc. In testing the stability, I left it running for 12 hours (FFmpeg is used for encoding), no hitches (resulting file around 800MB). Can also record webcam (just change video source) or audio only. It really is a Swiss Army Knife. Open source, on Github, multilingual. I have no affiliation other than being a happy user.
