ScreenFlow is a full recording studio for Mac OS X Leopard that captures screenshots from your computer screen, or the iSight camera, and mounts them to be played in sequence.
The application can capture images from multiple resources simultaneously. Just select the required combination before begining the capture: the images and sound from a computer screen, and images and sound from an iSight camera.
The video editor that comes with ScreenFlow is multitrack and very easy to use. You can split up the captured clips and apply various special effects to them, such as scaling up certain areas to stand out more, and rotating the images to give them a new perspective. It is also possible to adjust the audio levels.
Another interesting feature in ScreenFlow is the ability to highlight and focus in your mouse, to increase your accuracy while tracing, or the front most window.
Note:
For Mac OS X 10.5 or later.
