The visual effect of rotation in the video is a combination of the rotation of the sun and the orbit of the Earth around the sun (the satellite that took the images used to create the video is in orbit around the Earth[1]). Ballpark combining the rotation of the sun and the orbit of the Earth gives a rotation period of about 26-27 days[2], so during the video (made from 16 days of images), the Sun would appear to rotate about 16/26.5 * 360 = 217 degrees.
