In ScreenFlow, you don't need to define a capture region in order to record a clip of your display for your screencast. ScreenFlow records your entire computer display with an advanced algorithm that produces the highest quality recording and small file size—giving you the flexibility to make changes to your frame size in post-production.
You can set up ScreenFlow to record video and audio from various cameras and microphones, depending on your project, and you can change these settings any time you need to.
The recording options are identical in both windows. However, the Add Additional Recording window also allows you to close ScreenFlow automatically before recording.
