Key information includes the `name` (resource identifier), `expression` (image collection computation), `videoOptions` (animation settings), `fileFormat` (GIF support), and `grid` (image reprojection/clipping). Actions involve `create`, which generates an ID for rendering animated image collections, and `getPixels`, which calculates and displays an image based on a computation. These features define how dynamic visual data is processed and accessed.\n"]]
