Blurring the background of a sit down interview
Recently I conducted a video interview and now I need to blur out the background since it's distracting. I am looking to have the subject in focus by creating a letterbox frame (don't need to silhouette the person) and have what's in the letterbox frame in high rez, but everything outside the letter box should be blurry. I have tried Picture in Picture with no luck. I could use the crop tool to omit the background but since I did not shoot in 4K when it scales up the subject becomes very soft. Any help would be appreciated.
