Video Caption Auditor at Mercor

Video Caption Auditor | $20-30/hr | Remote (worldwide) | Hourly contractor

Short-term project auditing captions on egocentric (first-person) video — footage from a head-mounted camera showing hands performing everyday tasks like cooking, cleaning or crafting. You'll judge whether a written caption accurately describes a short video segment and give it a clear verdict. Your work helps improve how AI models interpret real-world human actions. The project is already underway, so people who can start quickly are prioritised.

What you'll do

For each video segment and its caption, you'll decide:

• Approve — the caption accurately describes the action.
• Reject — the caption has an error, rated Major or Minor, with the reason(s), for example: a wrong main verb (e.g. "wring" when the person is rubbing), a main action that is added, missing or out of order, a wrong object or tool, or the wrong or swapped hand (left vs. right).
• Exclude — the footage itself is unusable (corrupted, badly mounted camera, broken segment boundaries).

You'll follow a detailed written guideline with clear rules and examples, and judge only what is visible in each segment.

Who we're looking for

• Excellent attention to detail and patience for careful, repetitive visual review.
• Reliable left/right reasoning from the camera wearer's point of view.
• Strong English reading comprehension and a precise sense of word meaning (e.g. the difference between "wipe", "rub" and "scrub").
• Ability to learn a detailed guideline quickly and apply it consistently.
• Good judgment on ambiguous cases.
• Nice to have: prior experience in video annotation, data labelling, content moderation, QA, or AI training/evaluation work.

Pay and schedule

• $20-30/hr, paid hourly as a contractor.
• Short-term, fast-moving project with an accelerated onboarding process so qualified candidates can start promptly.
• Strong performance may open doors to additional AI training, annotation and evaluation projects.
