Adaptive foveated encoder and global motion predictor

A headset comprising:

• one or more non-transitory computer-readable media storing instructions executable to perform operations for producing a video, the video comprising an encoded frame that includes a focus region and a region having a lower quality than the focus region, the operations comprising:
• analyzing encoding statistics of one or more previously encoded frames, wherein the encoding statistics correspond to a focus region of each of the one or more previously encoded frames, wherein the encoding statistics indicate a number of bits that are used to encode each of the one or more previously encoded frames,
• determining one or more encoding parameters for a frame based on the encoding statistics of the one or more previously encoded frames, and
• generating the encoded frame by encoding the frame using the one or more encoding parameters;
• and
• a display device to display the video.
