It's a running joke in the production world that if something goes wrong on set, we'll fix it in post. In other words, we can use editing or VFX magic to get rid of that plastic bag that blew behind a person's head, or cut that take when your talent flubbed. But there's one thing we can never fix in post, and that's authenticity. If it wasn't captured on the day, it won't be in the final video.
