Alright, I surrendered and installed the game again just to try this and maybe have a second go at the story. I'm completely amazed at the possibilities this opens up.
Although, since as a filmmaker I'm much more interested by making some cool and twisted travellings, I find the controls a bit weird. I think the Crane shouldn't be on the D-pad but rather on the Up and Down L-Stick. The Dolly in and Dolly out should be on L2/R2 which are both unoccupied instead of the left stick. I think it makes much more sense and allows for better control during travellings !
This is my clumsy try at a very ambitious exploratory travelling :
