How do they film this ?

Hi

I was watching Sherlock Holmes: A Game of Shadows yesterday and i saw this this effect ( 1:50 http://m.youtube.com/#/watch?v=JucAVGwfs3Y). Anyone who knows how they filmed it?

A lot of cameras if I remember the scene correctly.. I can't view that link so I'm not to sure how the scene played out.

Go to youtube.com and search for sherlock holmes 2 forest scene and skip to 1:50

There is a video floating around youtube that shows the making of this scene albeit it doesn't go into detail of the process used. It does however show a track dolly used for the initial filming. I'd also guess that the majority of the close up shots of trees being ripped apart are composite pieces of footage added later. Some of the explosions are real, the rest having been added later.
Now as for the weird camera movement...
The footage looks like it was shot using a very high frame rate but as for the focused anchor point movements (that's the only way I can describe it) Ritchie must have used a program to lock the frame on a specific movement or part of the actor stabilizing the frame which allows the background to move around. He's been using a version of this technique ever since RocknRolla and, I think, started developing it as early as Lock Stock. Here are a couple of links:

Not a definite answer, just a theory...
