This is an animated movie set to the album Discovery. No dialogue other than the music of the album. Done by Toei Animation, a notable Japanese animation studio.
You may have seen the music videos for One More Time and Harder Better Faster Stronger. They were just part of a full narrative arc.
The animation was also overseen by the manga and anime legend Leiji Matsumoto [0] (famous for Captain Harlock, Galaxy Express 999, Space Battleship Yamato (Star Blazers), others). According to the Interstella 5555 Wikipedia page [1], Daft Punk wanted to work with Leiji Matsumoto because Captain Harlock had been a big influence on them when they were kids.
