Copyright on video of group

[smorodina]

I recorded a set of clips at the Russian Winter Festival last year. I have had a message from the first group featured, telling me that I don't have permission to use this and should remove it.

Does anybody know who owns the copyright to such filmed images - the director/producer (me) or the artist?
