http://www.varasoftware.com/products/screenflow/ http://www.varasoftware.com/products/screenflow/ seems to be the best tool for the Mac right now, at least according to all the big boys. It has features that few or none of the other solutions seem to have. E.g., the ability to record the camera at the same time as the screen, so you can have a picture-in-picture for the narrator at any point. Or, the ability to zoom and pan over the whole-screen recording at any point. It even knows at any given point where the frontmost window is, so you can select it after the fact during video editing. All in all, a pretty impressive new approach to screencast editing.
