Hmm, I'd say about 12-15 hours maybe, not entirely sure. I started it a day ago, and finished it this afternoon, only stopping to sleep and do some other work for around 4 hours of the day. I'm often told I'm a fast worker, so it'd probably take someone else a bit longer I'm guessing, as well as having worked with the program quite a few times before. Plus some of the images are altered versions of other ones in the video, so that cuts down the time quite a bit.
