Abstract
This disclosure relates to methods, non-transitory computer readable media, and systems that generate and dynamically change filter parameters for a frame of a 360-degree video based on detecting a field of view from a computing device. As a computing device rotates or otherwise changes orientation, for instance, the disclosed systems can detect a field of view and interpolate one or more filter parameters corresponding to nearby spatial keyframes of the 360-degree video to generate view-specific-filter parameters. By generating and storing filter parameters for spatial keyframes corresponding to different times and different view directions, the disclosed systems can dynamically adjust color grading or other visual effects using interpolated, view-specific-filter parameters to render a filtered version of the 360-degree video.
