節點平移製作時空重構鏡頭之可行性研究

A Research on the Feasibility of Making Space-time Reconstruction Shot by Using Nodal Pan

隨著科技演進，以矩陣思維選用各種技術後，電影可以造就出許多獨特的藝術表現。例如實現讓人物「重複」或「同框存在」的時空重構鏡頭，用來強調特殊的心理感受。而製作這種視覺奇觀鏡頭時，需藉由動作控制攝影系統（MOCO）的輔助來重複相同路徑的攝影機運動，才可精準完成多次拍攝同一角色的不同狀態。但MOCO卻有體積龐大和耗時與昂貴的特點，因此究明出以節點平移製作時空重構鏡頭是否可行，便有其意義。本研究藉由將劇本《全球通緝令》場99時空重構情節的試拍，在鏡頭設計形成、拍攝製作過程和後期效果檢視三個階段，取得視效預覽、鏡頭設計、實際拍攝、後期合成和成效檢視等研究資料，依序將其以內容分析法加以聚焦後彙整出6個方法、目的或任務。在影像效果面經雙向檢核與優化後，提出可提升鏡頭完成度的18項關鍵策略與重要觀念。據此本研究提出以下結論：節點平移製作時空重構鏡頭是可行的，它能作為當拍攝場地、條件與製作預算受限無法使用MOCO時的選用。同時提出「3618管理模型」，作為優化時空重構鏡頭完成度的管理依據。關鍵策略亦可延伸運用作為其他合成鏡頭製作時的參考。

"With the evolution of technology, films can create many unique forms of artistic expression by choosing various technologies with matrix thinking. For example, realizing time-space reconstruction shots, presenting characters ''repeated'' or ''in the same frame'' in order to emphasize special feelings. When shooting this kind of spectacle shots, it is necessary to use a motion control camera system（MOCO）to repeat the camera movement on the same path to accurately complete the shooting of the same character in different states many times. But MOCO is bulky, time-consuming and expensive. Therefore, it is meaningful to find out is it feasible to make space-time reconstruction shot by using node pan. In this research, through the test shooting of the space-time reconstruction plot of scene 99 in the script'' Theory of Ambitions'', in the three production stages of shots design, shooting production process, and review of postproduction effectiveness, visual effects preview, shots design, actual shooting and postproductions' research materials are obtained. Sequentially focus these on the content analysis method to summarize 6 methods, goals or tasks. After two-way inspection and optimization of the image effect, 18 important concepts and key strategies that can improve the completion of the shot are proposed. Based on the above, this research presents conclusions as: It is feasible for making space-time reconstruction shots by using node pan. It can be used when the shooting set, shooting conditions or production budget are limited and MOCO is unsuitable. Meanwhile, the ''3618 management model'' is proposed as the management basis for optimizing space-time reconstruction shots. And these key strategies can also be extended to be used as a reference for other composite shots production."
