Abstract

The invention relates to the technical field of digital video signal processing, and particularly discloses an intelligent transcoding and color consistency calibration method supporting multi-format film and television materials. The method comprises the following steps: decoding a source video, inputting the decoded source video into a dynamic color space perception and mapping core for synchronous double-path analysis, analyzing color metadata in one path, and extracting color statistical features in the other path through unsupervised visual feature analysis; fusing the two through an adaptive decision module to determine a real color attribute; dynamically synthesizing a color mapping model based on a target color space specified by a user and a calibration intention, and applying the color mapping model to pixel data conversion; meanwhile, the influence of conversion on image characteristics is analyzed, and a coding guidance strategy is generated; and finally, completing compression of the converted data by using the strategy in a single coding process, and outputting videos with uniform formats and consistent colors. According to the invention, deep integration of transcoding and color calibration is realized, the processing efficiency and the automation level are improved, and the color coherence of batch processing results is guaranteed.
