One embodiment includes a method that includes receiving a compressed video stream. The method also includes decoding a number of blocks of the compressed video stream to output a number of blocks of decoded video data. The decoding is based on at least one motion compensation vector. The method also includes deinterlacing the number of blocks of the decoded video data to output deinterlaced video data. The deinterlacing of one of the blocks of the number of blocks is based on the at least one motion compensation vector if a prediction error energy for the at least one motion compensation vector for the block is less than a threshold.
