The gif is lower quality than the mp4 or webm formats which we serve on our website and the embeddable GIFS player[1] if your browser supports it.
We've chosen to prioritize speed over quality for the initial launch so at this time but are working on transcoding to various sizes and qualities to return based on the client's device size and internet speed in the player or when someone wants to share a super high quality (and file size) GIF.
