Music video Edit
The dance version for "Galaxy Supernova" was released on September 4, 2013 and the PV was released on September 5, 2013. The video begins in silence with the GG members lining up in colored denim, which is reminiscent of the music video for "Gee" music video, and also features the girls wearing metallic and futuristic-looking dresses while dancing in a box set with LED lights serving as the background and two walls. The group also reuses the "arrow dance" from "Hoot" in the first chorus. The music video is well known for putting more focus on member, Sooyoung, as compared to other Girls Generation music videos.
A behind the scenes version of the music video was released on September 20, featuring scenes from the photo shoot for the collection as well as the group practicing their choreography.
