數位電影製作RAW檔案之運用研究－以短片《杏歡》為例

Abstract

Different in character from other forms of artistic express ion, the film image expresses itself through the elements in the visual arts such as time, space, motion, color, and lighting, and also emphasizes spatial representation. This kind of recording media malerial deeply influences the representational ability of the film image. As a result of trends in digital technology innovation, immediate usability has become the main criterion in choosing materials for film production Therefore digital production gravitates toward immediacy and gradually neglects the spatial expression characteristic in film image mentioned above. Therefore, in the context of digital production, knowing the various digital image productions and their characteristics, and carefully selecting the means of image expression is a priority. Examining the characteristics of the film image performance on the negatives and the difference in the RGB tri-color principle on the digital image, and conducting an empirical study on the digital production of the RAW file of the short film 《APRlCOT》, this article stresses that digital printing, digital dailies, and digital file management are the fundamental concepts of digital film production. Referring to the difference between RGB full-color incorporating negative and concept and YUV color sample coding, we also proceed with another empirical study on the ability of the RAW tiles image-expression in describing color and lighting. This led us to further stress that the familiarity of the production, the work procedure, and the concept of negative of the RAW code can improve the performance of video art, and the importance of onsite supervision and careful selection of digital file format in accordance with production needs, as we intend to offer appropriate concepts to this digital production trend.
