In reply to Chris the Tall:
Will give it a go:
Yosemite stuff is from Alone On The Wall
Motorbiking stuff is from One Crazy Ride
Headbutting, river crossing, Northern Lights, Leo Houlding and BASE Jumping stuff is from Asgard Project
Rail Slide and dirty snow jump are from Freezing Level
Most of the ski footage is from Ten - A Cameraman's Tale
The big ridge shot is from Mount Saint Elias, as is the guy falling through the crevasse.
The huge waterfall in a kayak (57m!) is Palouse Fall
The mountain biking is from Kranked: REVOLVE
Paragliding from Birdman Of The Karakoram
Chris Doyle grimacing and holding his hands up is welsh Connections as is Pete Whittaker falling of Quarryman
Wide shot of somebody running down a road with a bouldering mat is Keith Bradbury in his own Between The Lines
Children in native dress is Afghanistan - A Small Flame Of Hope
And the big water slide is of course, Project Megawoosh
We weren't able to get footage from at least half the films in time to put the trailer together, hence my comment about not showing all the best bits...
I've probably missed a few, but hope that helps,
