近年來，隨著影像晶片的蓬勃發展，攝影機功能不斷推陳出新。現今，剪輯方式從線性到非線性，更從單機進到多機剪輯，而拍攝設備也已全面從類比變成數位。為了完整記錄當下的實況，單機拍攝已無法滿足現今的需求，因多機拍攝除了能確保重要時刻鏡頭不會錯過，多機位剪輯創造出單機位所無法實現的視覺表現，多角度的視覺讓觀看者的視覺疲憊感必定會減少。目前，非線性剪輯功能日益強大，多軌道與多機位編輯技術更是日臻成熟。
決定從數位影片剪輯軟體作為研究內容，除了預估多機位拍攝已是未來趨勢之外，也假設多機剪輯軟體在設計上符合優使性的規準。目前業界較常使用的剪輯軟體有微軟公司為主的Canopus Edius、Premiere、威力導演…等；而Mac作業系統的剪輯軟體則有：Final Cut Pro、DaVinci Resolve…等。研究生目前對微軟作業系統較有涉略，因此，本研究將以微軟作業系統為主的Canopus Edius為研究的工具。
另外，本研究採用比較研究法與專家訪談法做為主要的研究方法。透過實際拍攝一場活動記錄，比較多機(三機)拍攝的差異，再利用目前業界常用的剪輯軟體-Canopus Edius與Premiere進行後製剪輯，盼提供未來想參與多機位剪輯的人，能對其使用介面有所了解。藉由雙機拍攝與剪輯流程的呈現，提供於多機拍攝前與後製剪輯時會遇到的問題，如：攝影機架設處、拍攝的影片畫框大小、多軌影片無法對位、聲音與畫面無法一致…等)，並針對剪輯軟體各項功能介面的優使性做評估。
多機位拍攝可透過鏡頭語言分析，從不同角度、不同場景詳實記錄現場，再利用非線性剪輯系統的多軌道多機位編輯技術，將不同角度所拍攝的素材整後，具有視角靈活、畫面豐富之優點。
在與幾位專家進行半結構訪談後，綜合他們的意見，提出：電腦配備、輸出效能、特效、多機位剪輯、字幕、使用介面、功能性等七大方向結合優使性做出比較，針對多機位拍攝與剪輯軟體間的對照與評估，提供給拍攝者參考單機與多機位剪輯軟體的差異，進而證實，多機拍攝搭配多機位剪輯雖然考驗著剪輯師的功力，但的確能夠增加影片數位內容之豐富性。而一套提供多機位剪輯的軟體，若能符合優使性的規準，必定能受到使用者的青睞。

In recent years, with the development of image chips getting more and more flurishing, the functions of camcorders are becoming versatile. From linear editing in the past to nonlinear editing nowadays, from analog to digital, the need of video shooting is also from single-cam to multiple cameras . In order not to miss any important cut, multi-cam shooting is the trend. With differnet angles of shooting, there is no doubt that it lessens visual fatigue. The technology of multi-cam editing is also becoming mature.
Multi-cam shooting can offer different angels and spots to films. Combining all the different sources will make the final edition look more special and attractive.
The reason why to choose digital film editing software is because I assume multi-cam shooting is the trend of the future, and the multi-cam editing software also meets the criteria of usability. As to my study, because I am short of enough information of Mac OS editing software, it focuses on video-editing software, such as Canopus Edius, Premiere, Power Director of Windows.
My research uses Comparative Methodology and Semi-expert Interview Methodology. Compared the single-cam to the multi-cam shooting and editing with one real activity record, I put them onto Canopus Edius and Premiere, the editing sfotware popular with many video editors. In my study, people who want to be in the multi-cam editing field can have more knowledge and understanding about it.
Besides, I hope that my study can offer those who want to make the video shooting to consider which is suitable, single-cam or multi-cam? In addition, via camera languages, people can know more about what the precautions of multi-cam shooting are, for instance, shooting angles, camera operation, the palce where the camera should be put, and so on.
After interviewing with some experts, I sum up their opinions about the ideas of the multi-cam shooting and analyze the software of equipment, output, multi-cam editing, subtitle, interface and function with the criteria of usability.
With all the information offered, it proves that multi-cam shooting and editing can really raise the acceptance and popularity of the audience, but, it is also a trial for a video editor. As to the softtware that meets the criteria of the usability will necessarily be widely used by the users.
