How can users create animated social media posts in Adobe Express?

Users can create animated social media posts in Adobe Express by utilizing the animation features specifically designed for text and images. This functionality allows for dynamic movement and visually engaging effects that can be applied to both elements in a post. For instance, users can animate text to fade in, slide, or likewise manipulate image elements to create a more compelling visual story. This feature enhances the overall impact of the social media posts, making them more eye-catching and effective in capturing audience attention.

The other methods mentioned do not facilitate the creation of animated posts. Applying static effects only affects the visual presentation without adding animation. Exporting videos instead of images is a different process and does not pertain directly to creating animations within the application. Lastly, while uploading GIFs can bring movement, it is not a method of animating text or images directly within the Adobe Express platform, as the focus here is on the built-in animation tools rather than relying on external GIFs.
