Video Editor - Post-Production Expert

About the work

Mercor is assembling a panel of professional video editors to build post-production tasks used to train and evaluate AI agents. Each task gives an AI agent what you'd hand a junior editor: source footage, a brief, and a deliverable spec, plus a hidden answer key or rubric so the finished video can be scored on the result, not on a text answer.

You will:

• Contribute original footage you shot and fully own (or source openly licensed footage) and author realistic editing briefs from it.


• Build each task end to end in your own editing software: cut, introduce defects or distractors where the task calls for them, and produce the reference edit a correct result is judged against.


• Write the grading criteria — concrete, checkable standards with the editorial reasoning behind them.


• Blind-solve tasks built by other editors and write up a step-by-step solution.

Background we're looking for

• 5+ years editing professionally in film and TV, commercials, broadcast news, or creator and social production, owning deliverables end to end.


• Fluent in at least one professional editor (Premiere Pro, DaVinci Resolve, Final Cut Pro, Avid Media Composer), including basic color and audio cleanup.


• Comfortable with delivery specs: resolution, frame rate, codecs, audio channel layouts and frame-accurate cuts.


• Strong plus: a library of unpublished original footage you shot and fully own, with people on camera who will sign an appearance release. The more, the better.

Before you apply

• Not open to residents of California.


• Expect about 12 hours/week.
