Negative cutting (also known as Negative matching and Negative conforming) is the process of cutting motion picture negative to match precisely the final edit as specified by the film editor. Original camera negative (OCN) is cut with scissors and joined using a film splicer and film cement. Negative cutting is part of the post-production process and occurs after editing and prior to striking internegatives and release prints. The process of negative cutting has changed little since the beginning of cinema in the early 20th century. In the early 1980s computer software was first used to aid the cutting process. Kodak introduced barcode on motion picture negative in the mid-1990s. This enabled negative cutters to more easily track shots and identify film sections based on keykode. Toward the late 1990s and early 2000s negative cutting changed due to the advent of digital cinema technologies such as digital intermediate (DI), digital projection and high-definition television. In some countries, due to the high cost of online suites, negative cutting is still used for commercials by reducing footage. Increasingly feature films are bypassing the negative cutting process altogether and are being scanned directly from the uncut rushes. The existence of digital intermediates (DI) has created a new demand for negative cutters to extract selected takes which are cut from the rushes and re-spliced into new rolls (in edit order) to reduce the volume of footage for scanning. == Basic negative cutting == After a film shoot, the original camera negative (OCN) is sent to a film laboratory for processing. Two or three camera rolls are spliced together to create a lab roll approximately long. After developing the lab roll, it is put through a telecine to create a rushes transfer tape. This rushes transfer tape is of lower quality than film and is used for editing purposes only. The rushes tape is sent to the Editor who loads it into an offline edit suite. The lab rolls are sent to the negative cutter for logging and storage. After the Editor finishes the Edit it is exported to an offline EDL list and the EDL list is sent to the negative cutter. The negative cutter will translate the Timecode in the EDL list to edge numbers (keykode) using specially designed negative cutting software to find which shot is needed from the rushes negative. Traditionally a negative cutter would then fine cut the negative to match the Editor's final edit frame accurately. Negative would be spliced together to create rolls less than which would then be sent to the film laboratory to print release prints. Today most feature films are extracted full takes (as selected takes) and scanned digitally as a digital intermediate. Television series and commercials shot on film follow the same extraction process but are sent for telecine. Each required shot is extracted from the lab roll as a full take and respliced together to create a new selected roll of negative. This reduces the negative required by up to 1/10 of the footage shot, saving considerable time during scanning or telecine. The negative cutter will create a new Online EDL list replacing the rushes roll timecode with the new selected roll timecode. In the case of feature films the selected roll and Online EDL are sent to a post production facility for scanning as a digital intermediate. For television commercials or series the selected takes and EDL are sent to a post production facility for re-telecine and compiled in an Online Suite for final grading. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Negative cutting」の詳細全文を読む スポンサード リンク
