Native HDR I/O: `LTXVLoadEXRSequence` → float32 VAE → `LTXVHDRDecodePostprocess` (`transfer=acescct`, optional EXR) → `LTXVSaveHLG` from `hdr_linear`. Same idea as pipelines `--hdr` on Distilled / IC-LoRA.
SDR→HDR IC-LoRA (separate from native EXR HDR): [LTX-2.5_ICLoRA_HDR_Distilled.json](./LTX-2.5_ICLoRA_HDR_Distilled.json) — `LoadVideo` → `LTXVSDRToHDRWorkingSpace` (`srgb_gamma`) → `Resize Image/Mask` (scale to multiple 32) → **fixed scene embeddings** (`LTXVLoadConditioning`, not a free-text prompt) → HDR IC-LoRA guide → float32 VAE decode → `LTXVHDRDecodePostprocess` (`transfer=acescct`, EXR=`acescct`) → HLG. Sampler **euler**; original audio frozen/muxed. Same idea as pipelines `hdr_ic_lora --text-embeddings`.
For native HDR, set **`img_compression = 0`** (Python `--hdr` EXR conditioning skips JPEG/CRF; CRF on ACEScct darkens highlights). Turn **prompt enhancer off** when matching goldens. I2V stage-2 distilled sigmas should be `0.909375, 0.725, 0.421875, 0.0` (not `0.85, …`). Inpaint keeps its own 2-step stage-2 schedule.
Python / pipeline equivalents of these ideas live in [pipeline-selection.md](https://github.com/Lightricks/LTX-2/blob/main/packages/ltx-pipelines/docs/pipeline-selection.md) in the LTX-2 repo.
