This is a video I made for my 300 youtube sub special that is about the portal 2 core transfer, and how it would be different if the events had taken a different turn. I uploaded it a while ago but I just now thought of posting it here.

It's nothing professional, but it is my first portal 2 cinematic video.
Enjoy.

That's cool. I wonder how the game's story would turn out. Also, how did you get that custom GLaDOS line?

All but a couple of those lines in that video (both wheatley and glados) were "sentence mixed", where I take existing lines and edit pieces of their speech together into what I want them to say. Some of them needed less editing than others

Because of my low expectations of this video I don't think it's just "cool". I think it's awesome! The lines are so damn well mixed! I'm telling you, this video just made my day. And it's still 9:30am here!

Sorry to necro, but...
This needs to be a fully fledged-out mod.

This is pretty cool.
