Screenflow video and speech in two separate steps

Is it possible, with screenflow, record video and in a second time record speech while watching the previous screen capture ? I prefer to record my voice with a scr开发者_StackOverflowipt and quietly :P

yes, that's possible. just record your screen. Then in the ScreenFlow helper icon at the top of your screen, select "Add additional recording" and make your second pass with audio, as you're watching your original video
