# HDR Demo Clips (Lightricks SDR→HDR)

Paired SDR (input) / HDR (output) frame sequences from the Lightricks SDR-to-HDR pipeline (IC-LoRA on LTX-2).

Each clip contains:
- `hdr_exr/frame_XXXXX.exr` — HDR output (f16, linear Rec.709/sRGB primaries, scene-referred)
- `sdr_png/frame_XXXXX.png` — SDR input (8-bit sRGB, display-referred)
- `thumbnail.jpg` — 280px preview from the middle frame

Dimensions: HDR is symmetrically cropped from SDR to match model-friendly dimensions (typically 28–56px removed from top+bottom for landscape, or left+right for portrait).

Used by the [HDR EXR Viewer](https://oumad.github.io/exr-viewer/).
