1. A computer-implemented method for comparing the performance of different encoders, the method comprising:
generating a first global convex hull of video encode points based on a first encoder, wherein each video encode point is associated with a different encoded version of a source video sequence;
generating a second global convex hull of video encode points based on a second encoder; and
computing a first performance value for an encoding comparison metric based on the first global convex hull and the second global convex hull.
