Adaptation of literature: A Pedra do Reino

I could never imagine to work in such a beautifull project as the Tv adaptation of "Novel of the Stone Kingdom" writen by Ariano Suassuna. The author dedicated his career to the exploration and transformation of the popular Brazilian culture into a high art form.
Following this philosophy, Luiz Fernando de Carvalho decided to adapt the novel into the screen. And he fulfil all expectation.

I have to admit that I take some high concentration for any Gringo to fully understand the dialogue of the film (portuguese language). But to be short the story is as follow. Quaderna, the lead character, is a popular poet who thinks to be the fourth of a true lineage of noble Brazilians. To salve himself from dishonor he write and explain the memories of fights, political and mystical adventures.

From the direction of art by Raimundo Rodriguez to the costume design everything is visually splendid.
The opening was done at Lobo and I
supervised the visual effects on the miniseries at Vetorzero.
There were in fact few things to do in the 3D part, but there were to be done as subtle as possible.
First some shot needed a CG metal bird to fly, another part was to integrate metal computer generated wings on some goodness, and finally invent some way to write fire on the air.

The first step to be done was to get the right track from the director point of view. And so this begun with the vizualisation of the shot to be done. Once again a great thing at Vetorzero and Lobo, is when you get the green light you get all the responsability for the job.

So for the wings shots example I started making some quick concept. I had some reference picture of a wing but it looked very stiff. Some studies were done until getting the right option, witch i then drew upper the footage to get a final look until begin the CG work.

The main effort had to be done in Tracking, Rendering and compositing.
The tracking can be a hard job when there aren t any preparation before and during the shooting. When you have to integrate virtual things into a footage you need to recreate the camera or/and objects movement into the computer. Without good preparation it can be a pain in the ..s job.
The Rotoscoping on any postproduction is an key factor. Actualy its one part that nobody see when its welldone. ( I ll show you some example later on in the blog). The objectiv is making mask to reveal or hide part of the images.

Here you can see how a single shot can be workexpencive. It s not about just making a wing moving. There is matchmoving the virtual camera to the real one, tracking the womans movement, modeling the wings (Danilo), Riggin the bones so that it simulate a mecanical (thiago-Guilherme) or organical mouvement when the animator (Alex and Michel) work on the shot, and shading-rendering, to simulate the light and material proprierety. So as you see lots going on. Finaly the material generated in HD will end to Bodao s hand, our compositing artist.
