TS LTX HDR Guide
Prepare one guide frame for both LTX stages, from an EXR when HDR is on and from the ordinary SDR chain when it is off. The unused branch is never computed.

Inputs (10)
| Name | Type | Default | Description |
|---|---|---|---|
| config | TS_LTX_HDR_CONFIG | Settings node. Its enabled switch picks the branch. | |
| stage1_width | INT | 96032–16384 | Width of the half-resolution first stage. |
| stage1_height | INT | 54432–16384 | Height of the half-resolution first stage. |
| stage2_width | INT | 192032–16384 | Width of the full-resolution second stage. |
| stage2_height | INT | 108832–16384 | Height of the full-resolution second stage. |
| fit_mode | COMBO | center_crop | center_crop fills the frame and trims the edges; reflect_pad fits the whole picture and invents the margins. |
| interpolation | COMBO | area | area averages by coverage when shrinking — the safe default. |
| sdr_imageopt | IMAGE | The existing SDR chain, LTXVPreprocess included. Used only when HDR is off, and not computed at all when it is on. | |
| hdr_linearopt | TS_LTX_HDR_IMAGE | The EXR loader. Used only when HDR is on, and not read at all when it is off — a broken EXR path cannot break an SDR run. | |
| image_guideopt | IMAGE | An ordinary picture (JPG/PNG) to guide an HDR run when you have no EXR. Used only when HDR is on and hdr_linear is not connected. The gamma is removed properly — treating the codes as linear light is off by up to 2.3 stops in the mid-tones. It adds no headroom: white stays at 1.0, and whether the model generates anything brighter is for TS LTX HDR Stats to say. |
