Some of this footage was used in an 80s documentary about the wreck, so it isn't completely brand new. There's been hundreds of dives to the wreck and thousands of hours of footage has been recorded, but most of it never gets released publicly. We only get to see a small portion that manages to make its way into documentaries or photos in books and magazines. Most of it was recovered decades ago, so there wasn't really any way to make it easily available to the public, but then again most footage from recent dives isn't public either. I'm honestly not sure why they don't release it.
