If you watch the commentary videos, he is using glitches upon glitches upon glitches... This run is to glitches what Inception is to dreams.
It's great listenning to him talk
"Well, we do this one glitch, and then if we do this while we do this glitch, another glitch happens, another glitch occurs after that glitch if we try and do this other glitch"
he spent a whole 10 minute video trying to do the first "jump over the acid pits" segment

he's using a glitch called "ABH" or "Accelerated Back Hop" basically, he's jumping over the acid pitsNouw said:

This guy if far more than just friend wit the companion cube, hes friends with every pixal of the game, allowing him to leap from room to room randomly. I also see why GlADOS is so violent now, this guy wouldnt let her finish one sentence before finishing the level. She would be talking "Welcome to the Apeture Scien-... oh you've made it to the elevator already...very well.."
Ok, basically, what he did was called an Edge Glitch and a Save GlitchPoisonUnagi said:
How it works: If you make a portal that's rectangular frame (although the image is circle, the portal itself is rectangular) goes slightly over the edge, you can glitch out the game. Your character avatar is technically in two places at the same time. You can see a legit version of this effect by looking at yourself through a portal. You see yourself, but that's not really you. That's an image of you. When you Edge Glitch, you use that other you to fire a portal.. It's really mindwarpingly insane and difficult to explain.
Basically, what happens is, you LOOK like you're in one portal, but you're actually on top of the other portal, but stuck inside the wall. That's called the Edge Glitch, Basically it lets you make blind portals through walls latching onto the outside walls of the level architecture.
If you save when you're in that state and then load, you will be locked into a state called "Save Glitching". In Save Glitching, you can clip through walls, but you will fall through any floor other then the one you start the save glitch on. It lasts until either you go through a portal, or you touch the emancipation grid.
What he's doing is getting stuck in the edge above the orange portal, then saving and loading (the video freezes for a split second at that point). Then he clips through the wall, then he uses another sort of non-glitch technique called a "Peekaportal" Basically, he fires off a portal, goes through the portal he's standing in and then exits through the portal he just made. In this case, he actually makes a portal that leads to the emancipation grid (which resticks him into the actual game, so he doesn't fall through the floor) at the end of chamber 3, so he skips the entire third chamber.
In the commentary it's explained that a large number of the glitches were common knowledge and are inherent to the Source Engine, although there are a couple that he discovered himself, notably the "Seam Portal" where you fire a portal into the tiny pixel width of a corner where the level architecture comes together and you can shoot a portal right through it, and if you know where to aim you can hit an important area. He shows off the basics of the Seam Portal right at the beginning with the piece of the cup, and he does it once or twice in the speed run.randomsix said:
The other is what he calls "Moon jumping" where you ABH (Accelerated Back Hopping, where you jump backwards to gain accelerated speed) while holding something, and then slam it into the ground to get extra air. This is what he does to get past the first jump where you get the companion cube when you do it legit. It takes literally 2 seconds in the final video, but apparently it took him 6000 tries to get it right. The next bit where he dodges the orb he only made it through that segment without the companion cube 2 times in 6500 total tries (and only made it to that part about 500 times)
EDIT: Oh, at 6:30, what he does is he gets himself into one of little side rooms that you see through frosted glass using an Edge Glitch, and then he uses the save Glitch to stick him there (that's sort of why the video goes all crazy before he grabs the chair). Then he uses a chair and rubs it against the wall. This is a Source Engine glitch that happens when you're in this sort of Save Glitch state - The chair stores up energy, so if you use it correctly you can use it to launch yourself through the air. This is another stunt that took up almost an entire 10 minute video for him to reproduce, because the direction and speed of your launch is almost entirely random.
Basically imagine that you could go through a wall, but a chair couldn't, and you can't go through the chair.. You push and push on the chair, and you build up all this potential energy, then you move the chair and all that energy is released and you launch through the wall. That's the jist of the physics, and that's basically what he's doing (although he's doing it sideways somehow).
The speed run video though, he hit the emancipation grid (returning him from the Save Glitch state) and landed inside the elevator perfectly. I watched the commentary video and he spend 10 minutes just trying that again and again.
Edit: Nvm, it got edited in.
I used the word "Basically" a lot in my explanations, but this shit is so crazy that it really needs to be said. Describing EXACTLY how he does what he does is beyond my computer programming skills. Needless to say, he doesn't HACK the game. The only script he used (besides the reskinned portal gun with his logo on it) was a "Turbo Jump", just so he could hold a button and have it jump over and over and over.. So he wouldn't have to hammer on the space bar everytime he needed to ABH.
If you guys don't want to spend 2 hours watching his commentary videos and would like more explanations of how he did those things without actually going and asking him, just post another "WTF@Time" comment and I'll try and explain it in everyday speak.

[spoiler="Portal Bumping" Glitch Basics]

I know I did 4 twice, I meant to remove the 4 on the Save Glitch section.
that's 2 different ways to break out of the level architecture
and you won't SEE the portal overhanging the ledge like that (and technically, it doesn't overhang by more then a couple pixels), but that's the jist of what's happening

While I applaud the effort I'm not impressed by it. If you're going to resort to glitching in your speed run why not just turn on no clipping and god mode? Yes I know this sort of nonsense is common but in any case where I notice it I am left similarly unimpressed.
It's fairly impressive, but not what I'd call a speedrun. Youtube is full of people abusing glitches in games and calling themselves pro, claiming world record speed runs. There's one of a guy completing Mario64 in 3 minutes because he manages to jump through a wall at the start of the game and end up right outside the final Bowser fight. It's not how the game was intended to be played. It's like me saying I can beat the London Marathon record because I'm going to use my car. Don't think it would stand.
This looks tool assisted, some of the moves are so precise that he either did this 10 billion times to get a near perfect run, or it's tool assisted (and he's still really good, figuring out the glitches and the best run line".
Thats, er, quite impressive I guess. Glitches and stuff don't normally interest me too much but it seemed quite clever really.
I still doubt the pixel-perfect ACCURACY of some of those leaps. The glitches themselves I believe, but hitting an elevator from a couple football fields away with a sling jump you had to create from a complex angle... I'm calling shenanigans on his pixel-perfect aim is all. And some of the footage looks spliced, which MIGHT mean this vid took more than one run. But I honestly don't know. My clip board is still in the toilet.
"Now you're thinking with glitches."
I mean impressive sure but I'd be more impressed if it was done with an intelligent use of portals, not glitches.
