Maybe it's like those Kingdom "Uncensored" releases. Where it is basically the same as the IV but without the music and some behind the scenes stuff left uncut so you get an idea of how the shooting process is like.
In most "making" scenes in IVs, it is usually another camera filming the process while in the Kingdom "Uncensored" is it the same footage as the released IV. And you can heard the cameraman/director communicating with the idol. I have not watched any Greatworks stuff so I'm just guessing. But if it really is 2hrs of behind the scenes footage from a totally different camera then that is a bit weird. It would be interesting to watch though.
