TS LTX HDR Settings
One switch for the whole native HDR path of LTX 2.5. Off, the graph behaves exactly as before and nothing HDR is loaded or computed.

Inputs (8)
| Name | Type | Default | Description |
|---|---|---|---|
| enabled | BOOLEAN | false | Turn the native HDR path on. Off by default so that an old workflow opens behaving exactly as it did. |
| input_color_space | COMBO | ACESCG | What the EXR files already are. ACESCG and SRGB_LINEAR are scene-linear and get encoded to the working curve for you; ACESCCT means the file is already encoded and is passed through. Same three choices as the official --hdr flag. |
| output_color_space | COMBO | REC709_LINEAR | What the master comes out as. Scene-linear Rec.709 is what EXR savers assume when they say 'linear'. |
| strict_validation | BOOLEAN | true | Refuse to continue on mismatched sizes, NaN/Inf or an SDR image fed into the HDR branch, instead of quietly making a master nobody can use. |
| preview_exposure_ev | FLOAT | 0.0-16–16 | Exposure of the SDR preview, in stops. Affects only what you look at — never the EXR master. |
| preview_tonemap | COMBO | reinhard_luma | How the preview squeezes HDR onto an ordinary screen. reinhard_luma is the neutral one, aces_filmic is punchier, clip just cuts everything above 1.0. |
| preview_dtype | COMBO | FP16 | FP16 halves the memory the preview takes. For 129 frames at 1920x1088 that is 1.5 GiB instead of 3.0 GiB. |
| hdr_mode | COMBO | preserve HDR from EXR (ACEScct) | Which HDR technology this graph uses. 'preserve' is the native LTX 2.5 path: the range came in from an EXR and must survive (ACEScct). 'expand' is the HDR IC-LoRA: there was no range on the way in and the model grows it out of ordinary SDR (LogC3). They are different technologies with different curves — mixing them shifts the colour. The LoRA is validated on LTX 2.3; support for 2.5 is, officially, in development. |
Outputs (2)
| Name | Type | Description |

| config | TS_LTX_HDR_CONFIG | Feed this into every other TS LTX HDR node. |
| enabled | BOOLEAN | The same switch as a plain boolean, for your own gates. |
