5.6.1.5 Technical Operations
The Technical operations team makes sure that depth tools (depth grading
systems, storage, media, monitors) work properly. Establishing and
maintaining directory structures, naming conventions, encoding,
transcoding (e.g., from high-res source to lower-res proxy versions) can be
part of their daily workload. The TechOps team is often responsible
for creating backups and archives of depth decisions and possibly
even previous versions of imagery. Titles of team members in this role
include:
• Technical Operations Engineer
• IT Person
5.6.1.6 Project Management
Leading the depth team are people responsible for pulling all of the elements
together. Team members in this role oversee not only the activities within
the workl ow, but make sure that activities in other workl ows integrate
properly with the depth workl ow. Titles of team members in this role can
include:
• 3D Supervisor
• Post Supervisor
• Post Producer
Depth teams are responsible for identifying and resolving depth issues.
Depth issues, by dei nition, are primarily spatial considerations as opposed
to temporal ones. We assume that imagery in the depth workl ow has been
edited and has had geometry issues resolved, thus resolving any temporal
issues prior to depth work. Common depth issues include:
• Depth Jumps
• Edge Violations
• Excessive Far (Positive) Parallax
• Excessive Near (Negative) Parallax
5.6.2.1 Issue: Depth Jumps
Depth jumps occur when areas of interest in the scene move unexpectedly
forward or backward in Z-space. Depth jumps can occur within a shot or
in transitions from shot to shot. Takes of the same shot can have different
