Oh there’s definitely editing! But lots of tricks you pick up to learn how to make it seamless. My buddy Aaron Francis has a course that covers a lot of these if you ever wanna get into it yourselfSam Selikoff
No matter how much you prepare, you are going to mess up, and it is going to be frustrating. There will be times when you record an entire video only to realize you never turned on the camera. Or, you might find yourself hitting the hotkey to stop recording, only for ScreenFlow to say, "Great, I'll start recording now." You'll discover that you never started recording and just did a perfect video without capturing any of it.
Every one of these experiences is frustrating, but I assure you, you're not alone. It has happened to me, and many other screencasters out there. However, here's some encouragement: every time this happens, the second take is usually better. It's frustrating, but ultimately, the product improves.
When this happens, take a deep breath and keep going. It's somewhat of a rite of passage in screencasting. Share your experience on your favorite social network—it's great content and relatable to many. You’ll find fellow screencasters who have been there too and are ready to empathize.
So when you mess up—and you will—remember, you're in good company. Keep going, and rest assured that your next take will be even better.
