What action should you take to compress media for standard quality in PowerPoint?

To compress media for standard quality in PowerPoint, the correct action is to use the Compress Media dialog. This feature allows users to reduce the size of audio and video files embedded in presentations, which is particularly useful for optimizing a presentation for sharing or delivery. By selecting this dialog, users can choose different quality options, such as standard or high quality, which can help manage file size without significantly impacting overall quality.

Accessing the Format Ribbon Tab primarily deals with specific formatting options for selected objects but does not directly relate to media compression. Opening the backstage view, while beneficial for other settings and document management tasks, does not lead directly to media compression options. Clicking the Enable Content button is relevant for security and enabling macros or content but does not address media compression. Therefore, the most effective choice for compressing media to a standard quality is to select the Compress Media dialog, providing a direct method to ensure manageable file sizes.
