The invention discloses a general video digital watermark method mainly comprising analysis, embedding and extraction processes of a system design scheme. The analysis of the system design scheme comprises determination of a system function, watermark algorithms Ai to be embedded, embedding proportions of all algorithms and minimum extraction frame number Fmin; the watermark embedding process comprises frame distribution of a video file, watermark information pre-processing, embedding of watermark algorithms and formation of video files containing watermarks, wherein the embedding of watermark algorithms comprises the steps of: calculating embedding frame numbers, selecting embedding frames and embedding the watermark; and the watermark extracting process comprises frame distribution of the video file, selection of video frames to be detected, extraction of watermark information and calculation similarity. In the invention, the plurality of watermark algorithms are embedded at the same time and the embedding proportions can be selected, thereby the watermark method obviously enhances attack-resistant property; the watermark embedding ensures the appreciation and the embedding speed of the video file by using a non-frame-by-frame embedding way; in the watermark extracting process, the number of the detecting frames is less and the detection efficiency is improved; in addition, the general video digital watermark method also intensifies the capability of resisting frame edition.
