What does the Fade Effect do when applied in Avid Media Composer?

The Fade Effect in Avid Media Composer is designed to create a gradual transition for titles, allowing them to fade in or out smoothly on the screen. This effect is particularly useful in enhancing the visual appearance of text or graphics, providing a professional look to the project by making the titles appear more integrated with the video content. While other effects might be used for transitions between clips or to create slow motion, the specific purpose of the Fade Effect pertains to titling, making option B the correct choice.
