The Timeline That Builds Itself

How We Build

João Verissimo is a Motion Director at Fantasy. Using Claude Code, he built a tool that turns a brief into a script, an AI voiceover, and a Premiere-ready timeline.

The AIA Timeline Builder interface: a brief step that generates a script with AI and a recording step that transcribes a take, layered over a Premiere-ready timeline.

What made him build it?

The build_timeline.jsx script Claude Code wrote to automate Premiere Pro, shown beside the AIA Timeline Builder web app it exports from.

What did the first session in Claude Code look like?

When did it stop being a side project?

The AIA Timeline Builder feature set built week by week: import and build, script and segments, AI voiceover, accessibility, and the assembled Premiere timeline.

Did building it "in the open" change the outcome?

We're making these in a fraction of the time and cost, and they still look and feel bespoke, right down to the brand guidelines.

Where did Claude Code struggle?

A motion designer converted a manual process into a tool that writes the script, generates the voiceover, and assembles a Premiere-ready timeline, and it moved from his laptop to a live client engagement in about a month. Claude Code built every feature he asked for, which freed him to spend more of his time on the story and flow of the videos themselves. While the final touches and verdict remain with the expert, the tool got him to that finish line faster.
