Abstract:
Embodiments of the present disclosure provide a method that comprises receiving a first stream of video frames at a first frame rate and generating a second stream of video frames at a second frame rate. The method also comprises interpolating between a pair of adjacent video frames of the first stream of video frames to produce a first number of interpolated intermediate video frames in a particular sequence of the intermediate video frames. The method further comprises duplicating at least one of the adjacent video frames of the pair of adjacent video frames to produce a second number of duplicated intermediate video frames in the particular sequence of the intermediate video frames. The method further comprises, in response to a change in observed interpolation quality, dynamically changing the first number of interpolated intermediate video frames and the second number of duplicated intermediate video frames.
