The invention relates to a method of encoding a sequence of frames, by means of a three-dimensional subband decomposition applied to successive groups of frames together with motion estimation and compensation steps. As these steps lead to some unconnected pixels that highly impact the resulting picture quality, it is proposed, according to the invention, to reduce the number of unconnected pixels by performing, when a motion vector points from a current frame B to a sub-pixel position in a previous reference frame A, a truncation of said motion vector to point to an integer pixel of said previous frame located in the neighboring of said position and depending on it. |
