Realistic 24 frames per second output from high frame rate content

Abstract:

A method of converting an input frame rate of input video frames includes upsampling at least some of the input video frames to produce upsampled frames at a higher frame rate than the input frame rate, applying a filter to combine together multiple frames at a single pixel location, downsampling the upsampled frames to an output frame rate. A method of converting an input frame rate of input video frames includes grouping input video frames together, wherein a number of groups per second is less than a capture frame rate, and interpolating the frames within a group to obtain a desired shutter angle, wherein an average time between frames within a group is less than a time between groups.
