What function does the source monitor panel serve in a video editing workflow?

The source monitor panel plays a crucial role in video editing by allowing editors to preview individual video clips or assets before incorporating them into the timeline or the edit. This functionality is essential as it enables the editor to assess the suitability of the clips for the project, select specific in and out points for trimming, and ensure that the desired content is obtained before further editing takes place.

This previewing capability is especially important when working with various assets that may contain multiple takes or angles. Adjusting audio levels, exporting projects, or displaying the project's timeline pertains to different aspects of the editing process and does not specifically involve the primary function of the source monitor, which is focused on previewing and selecting footage.
