A method for encoding motion-compensated video data includes generating, for a current frame, a high-pass wavelet coefficient based on a function of pixels in a temporally adjacent frame. The operations are repeated for multiple pixels in an array of pixels in the current frame to form an array of high-pass wavelet coefficients. A low-pass wavelet coefficient is generated based on a function of the high-pass wavelet coefficients. A system for coding video data includes a temporal wavelet decomposition module decomposing a pixel into a high-pass coefficient by performing a discrete wavelet transform on the pixel, a function of pixels in a previous frame, and/or a function of pixels in a subsequent frame. The system includes a motion estimation module generating motion vectors associated with the pixels in the previous frame and in the subsequent frame.
