What Is HD-EPIC?

HD-EPIC is a published highly detailed egocentric kitchen video dataset with interconnected labels grounded in 3D. Firsthand is not part of it.

Last reviewed: October 2026

Short answer

HD-EPIC is a published dataset of newly collected, unscripted kitchen egocentric video from a CVPR 2025 paper (arXiv 2502.04144). It is described as 41 hours of video in 9 kitchens, with interconnected labels for recipes, actions, ingredients, moving objects and audio, all grounded in 3D. Firsthand is not part of it.

01

What is HD-EPIC?

HD-EPIC is introduced in HD-EPIC: A Highly-Detailed Egocentric Video Dataset (arXiv 2502.04144), with an official project page and an official GitHub annotations repository. The abstract calls it a validation dataset. Read: the abstract, the project page and the repository README only.

02

Where does Firsthand fit next to HD-EPIC?

HD-EPIC is third-party research. Firsthand is not affiliated with its authors and claims no use, training or compatibility with it or any named model. Firsthand captures first-person human video, fast, on demand and to a written spec: 21 keypoints per hand with a visibility flag, wrist trajectories and action segments, plus one task instruction per episode.

03

How was HD-EPIC recorded?

The abstract describes newly collected kitchen egocentric video from unscripted recordings in diverse home environments, and the project page calls them unscripted multi-day recordings. It states 41 hours in 9 kitchens, with annotations grounded in 3D through digital twins of the scene. The README’s intermediate-data section refers to per-video Aria glasses device calibration, per-frame camera pose and gaze. Camera specs, resolution, participant count and consent process are Not stated in the sources read.

04

What annotations and benchmark does HD-EPIC include?

The abstract lists recipe steps, fine-grained actions, ingredients with nutritional values, moving objects and audio, primed with gaze. The abstract counts 59K fine-grained actions, 51K audio events and 263 annotations per minute. The repository releases narrations as a pickle, audio as CSV and the rest as JSON.

The benchmark is visual question answering: 26K questions in the abstract, 26.6K on the project page, across seven categories from recipes to gaze. The abstract reports Gemini Pro at 38.5% and calls the benchmark difficult. Firsthand draws no comparison from that score. Scores for the action, sound and segmentation assessments are Not stated in the sources read.

05

How does HD-EPIC compare with EPIC-KITCHENS and Ego4D?

HD-EPIC is a separate dataset from EPIC-KITCHENS, and the table keeps each source’s facts apart. The sizes differ: 41 hours here, 100 hours in EPIC-KITCHENS-100 and 3,670 hours in Ego4D, per their entries. This page ranks none of them. HD-EPIC licence terms are Not stated in the sources read.

06

What does a kitchen video benchmark not cover for robot manipulation?

The sources read describe HD-EPIC as a validation dataset and a question-answering benchmark, alongside recognition and segmentation. They do not describe robot actions or 3D hand pose keypoints; hand masks are pixel regions, not keypoints. Suitability for training a manipulation policy is Not stated in the sources read, and this page draws no conclusion. The scope is kitchens only.

07

How do you get custom egocentric data for your own tasks?

Write tasks, environments and signals into a spec and confirm them on a Spec Pilot. Median time to first validated batch: 48 hours where coverage is deep, three to four weeks where thin. Recipe, nutrition, audio-event and gaze labels like HD-EPIC’s are not fields this page states for Firsthand capture, so plan them separately.
