A method of encoding a series of frames in a video or media, including receiving a first key frame, receiving subsequent chunks of frames including at least one key frame, dividing each frame into a plurality of blocks, subdividing a first block (110) of the plurality of blocks into a plurality of pixel groups, averaging the pixels in each pixel group (112) to generate a single value, creating a first mini-block wherein each element of said first mini block corresponds with a pixel group of the corresponding first block and contains said single value, repeating for each block of each frame of the chunk, comparing a first of said plurality of mini blocks of a first frame with mini blocks of a second frame, where said second frame mini blocks are not necessarily aligned to mini blocks in the first frame, until a best match is achieved.
