Egocentric Video Datasets

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

What FourthHuman 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) 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 transparently at a published band — ₹250–400/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 settlement₹250–400/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. Stated plainly: we are pre-revenue with no customers, one validated end-to-end annotation run, and a Capture Partner network in pilot build-out. 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.
