Shot Orientation Controls for Interactive Cinematography with 360 Video
summary
Implements two concrete controls: viewpoint-oriented cuts automatically rotate the 360° shot at each edit to place a labeled important point in the viewer’s 18° central field, and active reorientation lets the viewer press a button to snap to a labeled point. A lab study with nine videos (three conditions) on Google Cardboard finds fixed cuts give 14% central viewing time while the new techniques increase important-point viewing by about 5.2–9.5%, and a hybrid combines both. The pipeline includes automatic important-point detection using optical flow and face/motion cues (mean 17° detection error) and published player/source code.
