Rotomation artists work with the data capture technicians and the live-action production crew to set up markers on set. Rotomation artists’ work is passed on to layout artists, who consider the framing, composition and camera angle of each VFX shot.
- Rotomation artists also do body and object tracking, using markers to recreate the movements of people, vehicles or other objects in CG.
- The motion files created (camera, object or body track) are then passed on to other departments via the VFX pipeline, so that, eventually, they can be seamlessly combined by the compositor.
- It needs to be pixel perfect, so they need an eye for detail. If the CG and live-action movements are not lining up perfectly, they have to find a way to fix this.
- Rotomation artists match computer-generated (CG) scenes with shots from live-action footage so the two can be convincingly combined.
- They recreate live-action backgrounds (plates) on a computer in a way that mirrors the camera on the set in every way, including lens distortion.
- They do this by tracking the camera movements to make sure the real and virtual scenes appear from the same perspective.
- Camera Tracking and match moving objects in live action plates for VFX projects
- Work collaboratively with other members of the 3D team and other VFX departments
- To roto-animate a variety of characters and / or objects that match the film backplates for various film projects and maintain consistent shot quality
- To be conscious of continuity between scenes when working with other Roto Animation Artists on the same character/rig.
1. Feature film experience using 3d Equalizer & Maya is essential.
2. Experience with 3D Roto Animation; matching digital models to live-action plates will be a plus
3. Experience using other tracking packages are advantageous (e.g.: Boujou & Syntheyes),
4. Thorough understanding of camera and rigid-body tracking, and use of survey data when generating camera and object tracks.
5. Experience working with Lidar and other onset data.
6. Understanding of real-world camera attributes such as apertures, lenses and distortion.
