Research And Application Of 4K Digital Movie Clip Technology

In the latter part of the film production field, a multi-linear editing system can be more practical than large institutions need to interact with the system and numerous film post system, which is composed of radio and television industry characteristics of the decision. In the 4K NLE beginning of the design firm to implement a concept: a comprehensive and efficient software to support the entire 4K post-process applications to a full-featured non-stop series to solve most of the latter part of the problem. This paper studies in 4K digital cinema editi ng process, a one-stop non-linear editing software package late in the production process with earlier HD(high definition) consistency in the field of film production generated by the depth directly 4K original quality video editing, special effects and a udio of packaging in non-linear editing software. Specifically, the paper describes the efficient nonlinear editing software to edit 4K digital cinema technology, focusing on the quality of the original algorithm 4K video processing, LUT color management l ookup table 4K color correction original quality video, plus multi-channel audio editing and decoding.That 4K digital cinema editing, the original file format can be directly imported to complete the clip does not want to transcode or re-decode generation. If the file format, frame rate, codec, there are still different sizes, not at a single time line is always optimized file smooth. In color process, 90% of the exposure, white balance, color saturation and fine-tuning are all available LUT solved by usin g LUT can quickly realize the film texture and color, do not need to adjust any node without changing the color correction; in the case of the original files of different display devices, if not the original image processing, it will not cause any damage, and can save a lot of rendering time, but also to meet the different needs of shades, and the process is simple time-saving operation. For audio editing, various changes, such as fade-in, fade-out, volume control, etc., converted by digital filtering algo rithms, such as high-pass, low-pass filter, supports up to 48 tracks, 15 low-orbit, more samples rate and bit rate, and data rate as 320 Kbps of ITU-R equivalent for the transmission of high-quality music 7.1.
