Terminalizer records terminal sessions and turns them into animated GIF images or recordings that can be replayed and shared. Sessions are saved to editable recording files, making it possible to adjust the captured frames and timing before producing the finished animation.
Rather than simply capturing pixels from an existing terminal window, Terminalizer renders the stored terminal contents. This gives considerably more control over the appearance of the resulting animation, including fonts, colours, terminal dimensions and decorative frames.
Recordings can also be replayed directly in the terminal. A configuration file controls recording and rendering behaviour, allowing commonly used settings to be retained between sessions.
This is free and open source software.
