MovingImages is a powerful scripting tool for post-production video editing. The MovingImages scripting platform works on OS X Yosemite. The scripting language used for writing post production video editing is ruby. MovingImages integrates three of Apple's graphics technologies. These are the drawing engine CoreGraphics, the image filter processing engine CoreImage and the video editing platform AVFoundation.
The goal of MovingImages is to provide a data format that can describe non-linear video editing using the three technologies described above. This is achieved using JSON command objects and JSON drawing instruction objects. Any scripting language that can create JSON data can be used to work with MovingImages. Zukini has made it easy by writing the moving_images ruby gem to write scripts in the scripting language ruby. I recommend watching the first episode of the video getting started with MovingImages before installing.
