This is the montage sequence from Mamoru Oshii's 1995 film, "Ghost in the Shell". I decided to upload it because I haven't seen it on YouTube yet, much less in 1080p.
This montage is my favorite part of any movie I have ever seen up to this point in my life, and I feel like that's saying a lot for me. It is very powerful and awe-inspiring.
Fun fact: The file I had for the film was in .mkv, and I couldn't edit that easily, so I actually recorded this clip with Fraps in VLC player, and edited the 3 .avi files it produced. Notice the quality did not suffer. :)
