Egocentric video datasets

Gaze-aligned, first-person demonstration capture, specified to a brief, for embodied-AI pretraining and policy learning.

What Fourthuman does

What a brief captures

A capture specification pairs first-person video with the telemetry a policy needs (IMU streams and a 3D camera trajectory), and every clip is annotated against the open FH-Ego v1 schema. Nothing here is stock: the brief defines the task, the environment and the rig before anything is recorded.

How provenance works

Every clip carries a SHA-256 consent receipt in a hash-chained, DPDP-aligned ledger, so a buyer re-verifies one clip instead of trusting a badge. Automated face redaction (YuNet where the host provides it, an OpenCV cascade where it does not) runs server-side at ingestion, before any human review, and fails closed; it refuses to emit a clip rather than emit one un-redacted. Licence plates are not covered. We hold no third-party attestation: no SOC 2, no ISO 27001.

What a brief costs to scope

Scoping is a conversation, not a price list: environment, session length, sensor rig and annotation tier each move the number. Capture Partners are paid from a published floor of ₹229/hr of accepted capture, by UPI on QA approval, no agent in the middle and no deduction. Those are the terms partners will be paid on, not a payout rail already running: the Capture Partner network is in pilot build-out and no payment provider is integrated.

What an egocentric brief pins down

A third-person video shows an action from an arbitrary, uncalibrated angle. A humanoid or mobile manipulator sees its workspace from where its own cameras sit, which is the whole reason gaze-aligned first-person footage maps from observation to control. Six things have to be fixed in the brief before a single clip exists.

Specified per brief, agreed before commissioning
What the brief pins downHow it is specified
Capture rigRay-Ban Meta, a chest mount, or a global-shutter stereo head rig, chosen for the task rather than for convenience
Optical calibrationLens intrinsics (K), stereo baseline (T) and radial-distortion coefficients logged per device, so pixels back-project into a metric 3D frame instead of an approximate one
DomainThe environments the brief names. Capture Partners for that domain are recruited when the brief is commissioned, and hub build-out is in pilot
Pay and settlementFrom ₹229/hr of accepted capture, by UPI on QA approval: no agent in the middle, no deduction. A term of the brief, not a rail already running: no payment provider is integrated
ConsentDPDP-aligned digital consent, held per clip in the hash-chained ledger with revocation

Commission a brief

Tell us the task, the environment and the policy you are training, and we scope a capture brief against it. The catalogue The catalogue lists capture specifications you can commission, with target volumes and their real availability status.

If you have been working from Ego4D or EPIC-KITCHENS and hit their non-commercial licence, that is the usual reason people write to us. A commissioned brief is licence-clean by construction, because we captured it for you.
