Well if it is specific footage of a specific place I don’t really know that I would consider that “stock” footage and I think you sell yourself short by using that term. When I think of stock footage I think of footage of a barn, a city street, a building on a database somewhere where the name of the artist doesn’t matter. Not a specific barn, a specific city street, or specific building and certainly not specific clips taken by a specific artist.
Your question should really be is how much to sell a video license for. Many if not most artists make their art first and then sell it later. I don’t see why this is any different just because you’ve already created the video.
How much would you charge if someone came to you and asked you to recreate these videos? That would be a good starting point for you to come up with a number.
