Which toolbar feature helps to assess the quality of clips imported?

The Inspector Panel is the correct answer because it provides detailed information about the selected clip, allowing users to assess various attributes of the clip, including its quality. It displays metadata such as resolution, frame rate, and codec information, which are essential for evaluating the technical quality of a clip. This feature allows editors to make informed decisions about which clips to use in their projects based on their specifications and quality criteria.

While other options have their functionalities, they do not focus specifically on assessing the quality of clips to the same extent. The Clip Quality Meter does not exist under that specific name in Final Cut Pro, the Info Panel generally displays basic information but lacks in-depth quality assessments, and the Media Viewer is primarily used for playback, not for detailed evaluation of clip characteristics.
