The paper is executed to manage the data stowing away in compacted video in movement vectors i.e. we can say video steganography. Since pictures and crude recordings are helpless against assaults, in compacted video we concentrated on the movement vectors to shroud the data by making utilization of forward predictive (P) frames and bidirectional (B) frames.
