Which panel would you likely use to review a clip before adding it to a sequence?

The Source Monitor Panel is specifically designed for reviewing clips before adding them to a sequence. In video editing software, this panel allows you to load and view individual clips, providing playback controls and options to trim or mark in and out points. This functionality is crucial for editors who need to evaluate the content and quality of a clip before deciding how and where it will fit within a larger sequence.

In contrast, the Timeline Panel is used primarily for arranging video clips and audio tracks in a sequence after they have already been imported. The Project Panel is where all your media assets are organized and stored, making it easy to locate them, but it doesn't provide the detailed review functions that the Source Monitor does. Lastly, the Effect Control Panel is used to adjust effects that have been applied to clips already placed in the timeline, rather than for reviewing clips. Thus, the Source Monitor is the go-to tool for previewing and preparing clips before insertion into a sequence.
