Abstract

The invention relates to a method for sub-pixel motion-compensated video encoding comprising, for an incoming video séquence frame, the steps of: dividing the frame into macroblocks and macroblock partitions, - determining a motion vector and an interpolation filter, from a set of interpolation filters, for a macroblock partition, for estimating fractional pixel displacements of said macroblock partition, determining a partition mode for a macroblock, performing motion compensation of a macroblock partition according to the determined partition mode, motion vector and interpolation filter, and wherein the step of determining an interpolation filter and a motion vector for a macroblock partition comprises determining an interpolation filter and a motion vector which minimize an coding motion cost indication for that partition of the frame macroblock.
