I work for a festival in the digital department. I received a request from a documentary filmmaker about wanting to use a portion of a live-streamed footage of our concert. The clip lives on our YouTube channel, which is where the filmmaker came across it. In the contract with the performing band, it stipulates that the festival reserves to right to live stream the performance and place on YouTube in perpetuity, and also that media outlets may use record and use 2 minutes of the performance (doesn't say of the 'livestreamed' performance). It doesn't say anything about allowing a third party to use it for another type of a production (=documentary).
My question is: who owns rights to this footage? The festival, the company that did the livestreaming, the band, the band's label? Do I (as the festival) have a right to give permission to use the footage to this filmmaker? If I should refer them to someone else, who should it be?
If it helps, I am in Canada, the artist from Columbia, as is the filmmaker who made the request.
