OK, just backing up the PC glitchers here.
The jumps were done with 60 FPS, which is what we get on ps3 (and xbox), so all of the jumps in the video are possible on PS3 and Xbox 360. It looks so good, and looks hard because they are all very good jumpers (jumping since CoD1 i believe).
PC also has the ability to save position, this makes it a lot easier. But the point is, all of these glitches are possible on console
