The massive dependence on digital interaction via multimedia tools like audio, images, and videos is leading to an era that will be digitized in almost every aspect. This credible development in multimedia technology with the easy availability of advanced cheap editing or tampering tools/techniques attracts the researcher’s community to ensure the multimedia content’s authenticity. This paper reviews video forensics, the statistical ways manipulations have been deployed on the data, and detection approaches for tracing the tampering attacks and challenges. The study gives better clarity for understanding the demand of direct relation for video content to be shared on social media platforms as the legal evidence towards the growth of tampering detection tools/technology. This paper gives a detailed review of the existing forgery attacks and passive forgery detection techniques. The video forensics algorithm is studied extensively, along with its limitations for varying datasets in an ordered manner. This discussion explores current active challenges in video forensics, raising scientific investigation and developing reliable multimedia forensics approaches.
