Thats a unique idea.You should consider the following idea to enhance your idea so that it would impact uniquely: Video forensics is an important research topic in information security. Particularly, video frame deletion and recompression are the most common manipulations.  studies a heterogeneous chain of video recompression that a forger firstly deletes frames from a video and then recompresses it with a different Group of Pictures (GOP). By analyzing the inherent periodic fingerprint in P-frame prediction error sequence, an effective method is proposed. Besides detecting tampered videos, the initial GOP size and the number of deleted frames are estimated. These parameters could be used to perform a more detailed analysis of possible forged videos. Experimental results demonstrate that our method can effectively detect the aforementioned heterogeneous chain and reliably estimate the specific parameters.
