I'm pretty confused too. It seems that Rondo Veneziao is a Italian chamber orchestra that does Baroque music with a disco beat. I think they're supposed to be the robots. I think La serenissima means The Republic of Venice and the buildings in the video do look like Venice. I'd guess this is a music video with lots of recycled animation set to Baroque disco music but the very end look like the video is supposed to continue. Other than all the recycled animation it's kind of cool.
