Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. Mikkel Lassalle (LTX-promotional, 2026-10-02 UTC). Steps: install ComfyUI (desktop or browser), Manager > Custom Nodes Manager > install "ComfyUI-LTXVideo" by Lightricks, drag the published layout-to-render workflow JSON into ComfyUI, download the six LTX models listed in the workflow notes into the folders shown (the missing-model panel offers copy-link), restart and confirm the load-models node. Inputs: a blockout render from any DCC (he uses Cinema 4D; Blender/Unreal fine) with only enough geometry to lock camera, composition, perspective, layout and timing, plus a reference/style frame (AI style frame, concept art, photo or live-action still) and positive/negative p...

Division of labour: the blockout says WHERE things are and how the camera moves; the reference image says what it should LOOK like. Runtime about 5 min without the upscaler on his machine (hardware not stated). Claimed related LTX post tools: HDR workflow expanding flat footage and keeping HDR in HDR, raw-in/raw-out ACES-preserving workflow, tiled 8K processing with overlapping tiles, and a refiner for blurry/low-quality video (stated, not demonstrated). Benchmarks vs Seedance 2.5 and MiniMax H3 are asserted, not shown. Licence: LTX community licence applies to model weights (see C3-B372 matrix; revenue threshold).

Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. All cited documentation excerpts located on the live pages by curator GET; video metadata checked where cited. Creator video (auto-caption transcript excerpts read by discovery; promotional/affiliate); not curator-verified beyond video metadata.

Limitations: Promotional; hardware unspecified; outputs not inspected; workflow file and model list not fetched here (description links).

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
