Troll Bridge is an upcoming comedy/fantasy film done collaboratively by VFX artists from all around the world.
I had the opportunity to work on this shot on my free time. Although the shot has only 81 frames it was challenging enough to learn really cool roto techniques in Nuke, such as open splines for fine detail. Furthermore it was really nice to work with a shot management system like SHOTGUN.
The shot required five iterations in order to get rid of most warping and sliding of shapes, and achieve a feature film quality level roto.
