Inputs (6)

Name	Type	Default	Description
fps_for_encoding	FLOAT	24.0001–60	FPS used when re-encoding a component-derived VIDEO (VideoFromComponents) to MP4 for the request body. Ignored when video_url is used or when the VIDEO is file-backed.
output_fps	FLOAT	24.0001–60	FPS reported on the `frame_rate` output socket. The EXR ZIP from the API doesn't carry a native time base, so this is what downstream consumers (CreateVideo, AM Write Image) will see for cadence.
poll_timeout_seconds	INT	60060–3600	Maximum total wait for the async HDR job to reach a terminal state (completed / failed). LTX results are available for 24h once terminal.
keep_temp_exrs	BOOLEAN	false	When On, the extracted EXR files are left on disk so downstream tooling (DJV, Nuke) can reach them. Off (default) deletes them after loading the IMAGE batch.
videoopt	VIDEO		Source SDR video. Native input type. When the VIDEO is backed by an on-disk MP4 (Load Video, another LTXV node) the original bytes are uploaded directly. Tier limits apply: ≤1080p max 181 frames, ≤1440p max 101, ≤4K max 41.
video_urlopt	STRING		Public HTTPS URL of the SDR input. When non-empty, wins over the `video` socket. Recommended for inputs that would balloon the base64 request body.

Outputs (6)

Name	Type	Description
image	IMAGE	HDR EXR frames as IMAGE batch (N×H×W×3 float32, not clipped to [0,1] — scene-linear values can and do exceed 1.0). The HDR endpoint is image-native; there is no VIDEO output socket. To re-encode for SDR delivery, wire `image` + `frame_rate` into stock CreateVideo.
info	STRING	Human-readable summary including the LTX job id.
width	INT	Frame width in pixels.
height	INT	Frame height in pixels.
frame_rate	FLOAT	Tagged frame rate (== output_fps).
frame_count	INT	Number of EXR frames returned.
