Screencasting is the process of recording screencast - a video stream of picture from the screen (desktop, application or a single window). It allows to see how another person works through the eyes of this person. Tutorials, announcements, conference talks - many things benefit from a quality made screencast.

In Python, Blender community uses screencasts a lot and they even made Python helper to aid the process of capturing screen with FFMPEG on Linux.

Helpful tools for recording and processing screencasts:

In Python

• recordscreen.py - video and audio capture for Linux with ffmpeg by Nathan Vegdahl, MIT

  • `python recordscreen.py -n -w --vcodec vp8 output.webm' - select window to capture, turn off sound, record into WebM

• key-mon - keyboard status monitor (Linux, Apache 2.0)

• Blender Key Status Script, GPL

Other

• LICEcap - GPL, non-Python tool for Mac OS and Windows that produces screencasting GIFs
