Publisher review:ScreenFlow proposes to create a video stream of your actions on the desktop MacOS X. In other words, ScreenFlow screencasting software is to create videos of what's happening on the screen of your Mac.
Among the features the software offers editing tools, 3D positioning features, or various export options.
