Module: Castanaut::Plugin::Ishowuhd

Defined in:
lib/plugins/ishowuhd.rb

Overview

This module provides primitive support for iShowU, a screencast capturing tool for Mac OS X from Shiny White Box.

iShowU is widely considered a good, simple application for its purpose, but you’re by no means required to use it for Castanaut. Simply write your own module for Snapz Pro, or ScreenFlow, or whatever you like.

Shiny White Box is promising much better Applescript support in an imminent version, which could tidy up this module quite a bit.
