Not to shamelessly advertise my own video, but I think you should've tone it a bit like I did http://www.youtube.com/watch?v=CzhjqLm7LOg
aka use timescale cheats to speed up the time. 12 minutes is a bit long and the sped up game sounds sound quite weird. The camera angle could've been better too.
Other than that, the video is nice. Loving the quality.
Thanks for the criticism! I take no offence to any help that anyone can give, since I am new to making videos! I may even start working on another video tonight, and try to make it even better!
I'm editing with Sony Vegas Pro 11, and I couldn't seem to get it to go any faster than 4x speed. Is there any solution to that? I tried velocity envelopes, but it repeated the clip multiple times when I turned it on.
