Sweet Video and great editing job.
Where in Whistler is that rock face, 2 minutes into the video?

the spearhead west face, Blackcomb backcountry about a 1.5 hour hike from the resort.

wow!... how do you make this "3d like" parts ?... like the last one ? sorry for my ignorance

Combination of photoshop and after effects.
There are tutorials out there- the tough part is breaking the still image into parts (foreground, subject, background) and building the missing parts realistically.
A great film called 'the kid stays in the picture' uses this effect throughout-watch it - its amazing.

Can you point me in the right direction for the tutorials for the 3d effects you do? I can see you cut out parts of the image and separate them on the z axis. I believe that is correct. Right? Thanks

i couldn't' find the original tutorial- its mainly good photoshop work then keeping separate layers in After effects making them 3d layers- positioning them (background , mid and foregound) then key framing a camera for movement in 3d space.

Amazing!
