Screencasting is the process of recording screencast - a movie, demonstrating the usage of some stuff on the screen. It is useful for tutorials, announcements and all kind of stuff. Blender community uses screencasts a lot and they even made Python helper to aid the process of capturing screen with FFMPEG on Linux.

Here are some Python bits and pieces that can help with recording and processing screencasts:

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

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

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