Abstract
Devices and techniques are generally described for encoding video data based on motion cues. In some examples, a first frame of image data representing a first view of a physical environment may be generated. The camera may be moved by a first amount in a first direction. A second frame of image data representing a second view of the physical environment may be generated. Intra-frame motion may be determined by subtracting a first vector representing movement of the camera by the first amount in the first direction from a second vector representing motion between the first frame and the second frame. Motion vector data representing motion between the first frame and the second frame may be calculated based on the intra-frame motion. An encoded representation of the second frame of image data may be generated and sent to a second device.
