Abstract
Systems and methods for utilizing on-camera sensor information to improve video and/or image encoding quality are discussed herein. Specifically, the systems and methods may utilize on-camera sensor information to efficiently determine whether to encode a particular frame within a set of frames as an intra frame. When captured on video, a particular arrangement of a group of pixels within a frame may comprise a visual representation of an object within the frame. When encoding video footage, motion information characterizing motion of an image capturing device over time may be used to predict displacement of an arrangement of group of pixels between frames. These predictions may be used to efficiently determine whether to encode a particular frame as an intra frame.
