Building the Pipeline.

I built the creative operating system the production needed.

Postvis needed a dependable route from incoming material to a director-approved target for Wētā FX. I made that route repeatable, then helped the department scale around it.

Executive impact at a glance

Why this work mattered.

Built and improved the Post Visualization pipeline and operating model across two Avatar productions. Standardized shot intake, creative targets, review, approval, and delivery helped increase team throughput approximately 30×, from roughly one approved shot per week to a sustained 30+, with peaks near 50. The system supported team growth from 1 to 18.

Output increased after pipeline, templates, review cadence, and ownership were redesigned as one operating system.

Operating model Built

Pipeline, review cadence, ownership, and delivery designed as one system.

Sustained output 30+ / week

Approved shots delivered during steady production.

Peak capacity ~50 / week

Highest-output production weeks after the system matured.

Scale enabled 1 → 18

The team expanded after the operating model became repeatable.

My contribution

I built and improved the postvis pipeline, templates, review cadence, and role ownership, then developed the team’s ability to run and improve that system. Final visual effects were delivered by Wētā FX.

Finding the real problem

The production did not need more isolated shot work.
It needed a trusted function that could scale.

Post Visualization occupied a narrow but critical point between live-action photography and final visual effects. The work had to earn trust in Jim Cameron’s review process, then hand Wētā FX a clear, approved creative target.

Fully CG sequences moved directly to Wētā FX. The live-action-with-CG path was the part that needed a dependable operating model, clear ownership, and enough capacity to scale with the films.

The transformation

What I inherited.
What I built.

The starting point was not simply one artist. Postvis had no established production pipeline, no dependable review model, and no operating system that could scale with the films.

At the start No postvis pipeline
  • No established shot pipeline, templates, or delivery standards
  • No scalable review cadence or production tracking model
  • Unclear interfaces with Previs, Editorial, and Wētā FX
  • Production capacity depended on individual knowledge and effort
  • One artist carrying an emerging function
What it became A dependable operating system
  • Repeatable shot intake, review, approval, and delivery workflows
  • Templates, tracking, standards, and documentation that reduced reinvention
  • Clear ownership and leadership depth inside the production ecosystem
  • An approved-template pipeline connecting postvis to final VFX
  • A system that enabled an 18-person team and 30+ approved shots per week

The Template

Our responsibility wasn’t to finish the shot.
It was to give Wētā the strongest possible starting point.

Every element was reviewed and approved by Jim Cameron before the template was delivered to Wētā FX. The final film frames shown here illustrate these decisions; they are not intermediate postvis templates.

Building the department

The pipeline made Post Visualization predictable, scalable, and trusted.

The important change was not adding people. It was making the path from incoming creative intent to an approved target and trusted Wētā handoff visible and repeatable.

04 TRUSTED HANDOFF Consistent delivery to Wētā FX

Built to continue

The highest compliment was that the system no longer needed me.

By the time the department had scaled, the important outcome was not another productivity graph. Reviews were clearer, handoffs were dependable, templates reduced reinvention, and ownership had moved into the team.
