摘要


隨著電腦發展與影片數位化之後,利用非線性剪輯(non-linear editing, NLE)已是目前業界的標準。在影片剪輯過程中,雖然非線性剪輯已提升工作效率,但在初期仍須依據場記表的記錄來對所拍攝的影片加以粗剪。將鏡頭和場次依照場記表的記錄,先將不適用的NG鏡頭予以刪除,再依先後順序加以接合,是相當耗費時間與人力才能得到初樣參考影片。因此我們試圖將非線性剪輯軟體透過XML程式架構與編輯模式,設計出適當的擷取點與時間碼,使影片自動產生一份完整的序列映像檔來彌補目前粗剪工作流程之不足,以提高工作效率。 本研究之目的主要在於建立一份符合場記表所記錄的XML粗剪工作流程。同時可將影片加以擷取重新排列進而得到初樣參考影片。為能達到此一目的,本研究採用實驗法並以Apple Xcode為工具,將文字形式的場記表透過實驗所撰寫的程式轉換為非線性剪輯所能接受的XML檔案格式。再從資料庫中取得一份場記表,交由實驗操作者分別使用舊有粗剪方式與XML粗剪方式進行實驗並記錄操作時間與實驗結果,判斷是否可節省時間達到工作效率的提昇。

Use of Non-Linear Editing (NLE) has been the standard process in this field with the prevailing in computing and digitalizing of films. While elevating production efficiency, it is still necessary to obtain rough cut of the recorded films according to the shoot log as an initial step. To obtain an initial reference film, takes and scenes are cut in sequential according to the shoot log after deleting useless NG ones, which is time consuming and laborious. To improve this, adequate capture points and time codes are arranged by NLE software with various XML program frames and editing modes, then a complete image sequence file is automatically produced therefrom, which step has not yet been seen in current rough cut process. The object of this study is to establish a working process for XML rough cut conformed to the shoot log, which is capable of producing an initial reference film through capturing and rearranging. The measure to complete this study is based on experimental method by using Apple Xcode to convert text format of the shoot log, via programs obtained from experiments, into XML file format available for NLE. A shoot log is picked from database, which is then subjected to experiments processing with conventional and XML rough cut to obtain operation duration. The elevation of efficiency is decided based on the saving of time.
