"You literally just wake up every morning and go shoot a movie, and it seems to last a lifetime," says Jackson at one point.
Another scene shows Martin Freeman, who plays Bilbo Baggins, joking around between takes, sitting at a table and quoting a line from comedy show Little Britain: "Write the theme tune, sing the theme tune."
Later on, Freeman says: "I'll miss the camaraderie of the folks that we've built up and the cast and crew. We've spent an awful long of time together, there's like 12 or 13 of us that have been in a mini-army."
Jackson recently announced that he could shoot more Hobbit footage - possibly turning the two Hobbit films into a trilogy - next year.
He said there were more "challenges" ahead in post-production, and he would keep posting video updates during that process.
The Hobbit: An Unexpected Journey is due for release on December 14, with a world premiere being held on November 28 in Wellington. The sequel, There and Back Again, is due for release on December 13, 2013.
