It explains that thumbnails were previously animated GIFs about five seconds long showing a random part of the video, and now you can update them by selecting a different video frame or uploading your own thumbnail image like on YouTube. The presenter demonstrates choosing a three-dot menu option to pick a frame from a video, adjust it, and save the new five-second animated GIF that will display across platforms. They also show how to switch to uploading a custom thumbnail for replacement.
