Curated scene-linear / display-linear HDR frames (human-passed, v1)

1170 EXR frames that passed a multi-round human quality review (watermarks, grain, jitter, degenerate/duplicate content removed) over a 41k-frame pool.

Format

• OpenEXR, RGB HALF, scanline, ZIP; Rec.709/D65 chromaticities embedded.
• Pixels are relative linear light: each frame group was normalized so the group's positive-luminance median maps to 0.18 (shared per clip / per movie; a group-level scale cap keeps values inside HALF finite range, no clipping).
• signal_domain per frame (see manifest): HDRVD2K / Sparks-ACES are scene-linear camera data (provisional color interpretation); HDR_MOVIES are graded display-referred content linearized from PQ/HLG (npl=100/1000).

Files

• metadata/pass_manifest.jsonl — one row per frame: sample_id, source, group id, signal domain, review label metadata.

Licensing / provenance (read before use)

Sources: HDRVD2K (academic dataset), Sparks (ACES/Netflix open content), and frames sampled from public HDR demo videos. Upstream licenses vary and were not independently re-cleared for redistribution; access is therefore gated and granted for non-commercial research only. You are responsible for verifying upstream terms for your use case.
