A method for temporal decomposition and reconstruction of an input video signal is disclosed. The method uses a prediction process and an update process in the framework of motion compensated temporal filtering (MCTF), the motion information used for the update process being derived from the motion information used for the prediction process, and the method employing a block based video codec composed of an encoder and a decoder, the decoder having a residual buffer. A residual picture signal is received, and in response to the signal being decoded in the decoder, the residual picture signal is clipped such that the residual picture signal is reduced in precision prior to storing it in the residual buffer, thereby allowing the codec to use a conventional picture buffer that stores a reconstructed picture.
