What optional feature can be included at the beginning and end of a PSA?

Including a black screen at the beginning and end of a Public Service Announcement (PSA) serves as an effective optional feature. This approach can create a visual pause that emphasizes the seriousness of the message being conveyed. The use of a black screen can also draw viewers’ attention and prepare them to engage with the content. At the conclusion, it may allow for reflection on the message or provide a moment for the audience to process what they've just seen.

Options like a motivational quote, a summary of the content, or a brief biography of the creators may be useful in different contexts; however, they do not serve the same functional purpose as a black screen in setting the tone or creating a powerful visual impact at the start and finish of a PSA. While quotes can be inspirational, summaries may not capture the audience's attention effectively, and biographies are generally more relevant in a credit or acknowledgment context rather than serving as a framing device for the PSA itself.
