What differentiates a QT movie from a QT reference file?

• A. A QT movie is larger in size compared to a QT reference
• B. A QT reference does not contain media, it references the project
• C. A QT movie is faster in playback than a QT reference
• D. QT reference files cannot be shared between different systems

Answer: (B)

A QT movie and a QT reference file serve different purposes in the context of video editing and file management. A QT movie is a self-contained file that includes both the video and audio data along with all the necessary media to playback the content. This file can be easily shared and played back on various systems without requiring any additional files or metadata because it carries everything within its structure. In contrast, a QT reference file is essentially a pointer or a link to the original media files used in a project. It does not contain the actual media; rather, it refers to where the media is stored on the computer or network. This means that for a QT reference file to function properly, it requires access to the original media files. If those files are moved or renamed, the QT reference may become unusable. The size difference between a QT movie and a QT reference is significant; because the QT movie includes all media, it is typically larger. The playback speed is not inherently different between a QT reference and a QT movie, as playback performance largely depends on the original media's quality and the system's capabilities. Moreover, QT reference files can indeed be shared between systems, as long as the referenced media files are accessible. So, the correct answer highlights that a
