What occurs when an imported clip is moved or deleted outside of Premiere Pro?

When an imported clip is moved or deleted outside of Premiere Pro, it becomes an offline clip. This occurs because Premiere Pro relies on the file path to locate the media files used in a project. If the original file is removed or relocated from its original directory, Premiere Pro can no longer access it, which leads to the clip being marked as offline.

When a clip is offline, Premiere Pro will typically provide a visual indication (such as a red "offline" badge) and allow the user to relink the media file to its new location if the clip has simply been moved. This is important for maintaining the integrity of the project, as it ensures that all media is properly linked and accessible during the editing process.

The other options do not accurately reflect what occurs in this scenario: a clip does not reappear upon reopening the program, it does not update automatically, and it does not cause the project to freeze. Understanding the concept of offline clips and the importance of file management is crucial for effective video editing workflows.
