So, how does this Video Boost magic work? You flick the switch before recording your video, and voila! After capturing your masterpiece (up to 4K resolution), you get a locally processed version on your device. At the same time, the footage takes a trip to Google’s servers, where they sprinkle some HDR Plus magic on every frame, just like they do with photos. The freshly processed clip then dances its way back to your phone, labeled with a fancy Video Boost tag.
