1. A method comprising:
generating one or more first motion vectors mapping first visual content displayed at one or more first pixel locations in a first reference frame of a sequence of frames to one or more pixel locations in an intermediate frame;
generating one or more second motion vectors mapping second visual content displayed at one or more second pixel locations in a second reference frame of the sequence of frames to the one or more pixel locations in the intermediate frame;
detecting, based at least on the first visual content and the second visual content, a conflict between the one or more first motion vectors and the one or more second motion vectors at least one pixel location of the one or more pixel locations in the intermediate frame; and
responsive to the detecting, generating pixel data for the at least one pixel location in the intermediate frame using at least one motion vector of the one or more first motion vectors based at least on the one or more first motion vectors having a greater similarity to a global motion vector than the one or more second motion vectors.
