【摘要】：在電影后期生產(chǎn)領(lǐng)域,一款多能的非線性編輯系統(tǒng)比需要龐大機構(gòu)和眾多交互系統(tǒng)的電影后期系統(tǒng)更加的實用,這是由廣播影視行業(yè)的特點所決定的。在4K非編設(shè)計之初就堅定的貫徹一個理念:以一款全面高效的軟件來支持4K的全部后期流程應(yīng)用,以一款全功能的非編來一站式解決大部分后期難題。本文主要研究在編輯4K數(shù)字電影的過程中,一站式的進行非線性編輯軟件后期包裝生產(chǎn)過程中保持與早期的HD(高清晰度)在電影制作領(lǐng)域所產(chǎn)生的一致性,深入探討了直接在非線性編輯軟件中編輯4K原質(zhì)量視頻、特效以及音頻的包裝生產(chǎn)。具體來說,本文闡述了在非線性編輯軟件中高效編輯4K數(shù)字電影技術(shù),給出了一種4K原質(zhì)量視頻處理的算法,并使用LUT(Look-Up Table)色彩管理查找表對4K原質(zhì)量視頻進行色彩校正,以及多聲道音頻的編輯和解碼。在4K數(shù)字電影剪接中,本文首先將文件原格式導(dǎo)入就完全直接剪輯,而無需轉(zhuǎn)碼或者重新解碼生成。如果文件的格式、幀速率、編解碼器仍存在尺寸的不同。則在調(diào)色過程中,使用LUT解決90%的曝光、白平衡、色差及飽和度微調(diào)等。通過使用LUT可以快速實現(xiàn)電影的質(zhì)感和色彩,不需做任何節(jié)點調(diào)節(jié),也不必改變對顏色校正;在原始文件不同顯示設(shè)備的情況下,如果不對原來圖像進行處理,不會造成任何損傷,且能節(jié)約大量渲染時間,同時也可滿足不同需求的色調(diào),而且流程操作簡單省時。針對音頻編輯,各種變換,如淡入、淡出、音量調(diào)節(jié)等,測試表明,通過數(shù)字濾波算法進行的變換,如高通、低通濾波器,支持多達48個音軌,15個低軌道,更多的采樣率和比特率,并在320 Kbps的數(shù)據(jù)速率的ITU-R可等效為7.1聲道的傳輸高質(zhì)量的音樂。
[Abstract]:In the field of late film production, a multi-functional nonlinear editing system is more practical than a post-movie system that requires a large number of institutions and many interactive systems. This is determined by the characteristics of the radio, film and television industry. At the beginning of the 4K non-editing design, the firm implementation of the idea: a comprehensive and efficient software to support all 4K later process applications, In this paper, we mainly study the process of editing 4K digital movie. One-stop non-linear editing software in the process of packaging production to maintain the early HD( high definition) in the field of film production, in-depth discussion of editing 4K original quality video directly in the non-linear editing software. The special effects and audio packaging production. Specifically, this paper describes the efficient editing of 4K digital film technology in the non-linear editing software, and gives an algorithm of 4K video processing with original quality. The color management look-up table of LUT(Look-Up is used to correct the 4K original quality video, and to edit and decode the multi-channel audio. In the 4K digital movie splicing, this paper first imports the original format of the file to complete the direct editing. If the file format, frame rate, codec still exist size difference. Then in the color adjustment process, using LUT to solve the exposure of 90%, white balance, Color difference and saturation fine-tuning. By using LUT can quickly achieve film texture and color, without any node adjustment, do not have to change the color correction; in the case of different display devices in the original file, If the original image is not processed, it will not cause any damage, and can save a lot of rendering time, at the same time, it can also meet the different needs of the hue, and the operation of the process is simple and time-saving. For audio editing, all kinds of transformations, such as fade in, fade out, Volume adjustment and so on, tests show that by digital filtering algorithms such as high-pass, low-pass filters, support up to 48 tracks, 15 low tracks, more sampling rate and bit rate, And at 320 Kbps the data rate of the ITU-R can be equivalent to 7.1 channels of transmission of high quality music.
