In recent years, the way of content communication has gradually shifted from analogy to digital. QR Code is an interface that connects the virtual and real world, but its aesthetics still needed to be improved. Therefore, this research beautifies and integrates QR Code into the video. In this study, the QR Code information was hidden in the corner areas of the three videos by the error diffusion algorithm, and the digital files and display-and-captured files were read and identified by error analysis. The results show that the aesthetic QR Code can be successfully applied to the video and content for value-added applications. It is also known that the QR Code recognition rate of darker image content will be poor, and it should be avoided in future applications. The decoding error trend of the digital files and display-and-captured files is consistent. The results of this research can make the integration and application of QR Code in videos faster and more convenient in the future, and it has many potential industrial applications.
