A method for video compression for storage in and matching against an index is described. A processing device receives a first media item and divides the first media item into a first plurality of subsequences. The processing device selects a corresponding first representative for each subsequence of the first plurality of subsequences to generate a first plurality of representatives and stores the first plurality of representatives in an index. The processing device receives a second media item, divides the second media item into a second plurality of subsequences, and selects a corresponding second representative for each subsequence of the second plurality of subsequences to generate a second plurality of representatives. The processing device compares the second plurality of representatives against the index and determines at least a partial match between the second plurality of representatives and the first plurality of representatives.
