摘　　要：影视调色技术在数字时代是影视后期制作领域的重要环节,随着数字设备的升级、算力的提高以及后期前置化理念的普及,影视调色技术开始以现场调色的方式出现在拍摄前端。在全媒体时代背景下,电影、电视、互联网等多平台交叉协同发展,影视现场调色工艺逐渐被应用于网络直播领域中。但网络直播现场调色与影视现场调色在调色需求、调色目标上有着显著区别,因此方案设计方向也不尽相同。本文通过分析影视调色的工作内容及特点,结合网络直播实际需求,以此来设计蔚来汽车NIO Day活动及耐克儿童官方直播活动中的现场调色方案,呈现出影视现场调色与网络直播现场调色在技术实现方法、调色目标及方案设计上的异同,最终提出一套理想化的网络现场调色方案。Colour grading becomes a key part of film and television post⁃production in the digital age.Not only with the up⁃grading of digital equipment and the increasing of computility,the concept of post⁃production propositioning has become more prevalent,colour correction technology has been used in on⁃set shooting.In the background of the all⁃media era,cross development becomes common in multi⁃platform not only among film,television and internet.Film production tech⁃nique has been introduced to live production.Nonetheless,using colour correction in live broadcast field has significant dif⁃ference with on⁃set shooting,hence the program designs would not be the same.This paper demonstrates the responsibil⁃ity and characteristics of colour correction in film and television industry.Considering the practical requirements of in live broadcast,this paper customizes on⁃set colour correction solutions for both NIO Day Event and Nike KIDS Official,while also presents its similarities and differences from film and television in technical implementation methods,colour correction objectives and program design,and finally puts forward an idealised colour correction solution for live streaming.
