Initially communication was restricted only till texture documents. Currently due to advancement in network technologies and development of multimedia systems, it was possible to have communication using various multimedia elements like images, audio files, video files etc. Started from static images, were information captured was limited only in one frame and moving a way ahead on these lines we have reached to dynamic images where information is conveyed in number of frames which are synchronized for motion and sound. As information transfer increased thus video file communication on the internet along with added security and threats to it also increased. One such threat is hacking of video files. Within the domain of hacking, the focus of this paper is on video forgery. This paper, examines various aspects of video forgery and from its types and methods for video forgery detection, then the best suited method is selected and within it an optimal algorithm is suggested. The video forgery detection is proposed as a system design approach which exploits various cases of forged video types in terms of its detection going upto the level of identifying the forged object in it.
