Complete scene

Hello, I asked here a while ago about the name of the entire video and recently I was answered, but the scene that the person provided me is not complete.
The entire scene should be approximately 40 minutes long and the person provided me with an 8 minute scene.

My next question is where I would find the Complete scene in good quality because I did find one but the quality is very bad.

If someone found the complete scene in good quality I would be grateful. I also tried searching on paid sites to see if the scene can be purchased somewhere, but unfortunately I did not find anything.
