Robustness and invisibility are all important points in video watermarking technology. In this paper, we propose the new scheme to increase the robustness and keep the invisibility as good. Through the experiment, we get the relationship linear curve between QP values and watermark strength values, and using that relationship, we get the better detection rate increased by 7%~14%. The performance increases are 6.94%, 8.03%, and 14.32% about MPEG2, MPEG4 and H.264 attacks respectively. For the subjective quality assessment, we experiment with the 23 general non-specialists. In spite of increasing the performance, we have still good invisibility which is checked by subjective test. It is difficult to obtain the distinction between the source and watermarked content statistically.
