Yes, though it is known as Cinematic Mode on iPhone, Samsung calls it portrait video or live focus video depending on the version of One UI you are using. It is simply, a portrait mode for video. All 4 phones in the S20 family have this feature and capability. To access this feature on One UI 4, just open up your camera app -> More -> Portrait Video or Live Focus Video. You can use the options available such as Blur, Color point, Big Circle, and Glitch to customize to your preference.
