Abstract: One embodiment of the present invention sets forth a technique for generation region-based user interest levels for use during video encoding. The technique includes identifying a plurality of view events associated with a frame of a video content, wherein each view event comprises field of view information indicating a region in the frame at which an interest of a given user was directed when the frame was being rendered, processing the field of view information included in at least a subset of the plurality of view events to generate per-pixel interest levels for a plurality of pixels in the frame, determining a plurality of regions in the frame including the plurality of pixels, generating per-region interest levels for the plurality of regions based on the per-pixel interest levels, and transmitting the per-region interest levels to one or more encoders for encoding the video content in a manner that accounts for the plurality of view events.
