 ScreenFlow does not capture specific regions of your screen when recording (you can select regions after recording).  It records the entire screen, but is highly CPU efficient due to its focus on actively changing frames.  Here is the basic flow:

 Screen recordings are 60 FPS by default.  Playback in the canvas isn't perfect, so it might look like frames were dropped in the recording even though they really weren't.  Assuming your hardware doesn't have performance issues, the encoded videos will show all the frames recorded correctly.
