Luma Ray 3.2 — Generate
Overview
luma-ray-3-2-generate uses Luma’s ray-3.2 model to create video from a text prompt (text-to-video) and from anchor images (image-to-video) via the Luma Agents API. It also covers extend and chain-referenced interpolation when a keyframe carries a prior generation id. Output is an MP4 (HDR is a request knob, hdr: true, not a separate model). For restyling an existing video use Luma Ray 3.2 — Edit; for aspect-ratio outpaint use Luma Ray 3.2 — Reframe.

Request Parameters
Modes
- Text-to-video: just a
prompt. - Image-to-video: set
start_frame_urland/orend_frame_url. Not supported withduration: 10s. - Extend: exactly one chain-ref keyframe —
start_frame_generation_id(forward, continues past the prior clip) orend_frame_generation_id(backward, prepends before it). Standard dynamic range only; returns one 5s block per call;loopis forward-only. - Interpolation: set both keyframes, at least one a chain-ref
*_generation_id.
Status
Video generation is asynchronous and takes longer than image generation (a 5s/720p clip is usually well under two minutes; 10s/1080p/HDR can run several times longer). The submit returnsstatus: processing with a request_id; poll until terminal:
status is queued → processing → success or failed.
Response
video_url). Use generation_id to chain a follow-up extend, edit, or reframe. Presigned URLs expire after ~1 hour — re-poll to mint a fresh one.

Pricing
Billed at the create-tier per 5-second block. A 10s video is two blocks; each extend call returns one 5s block.
HDR and HDR+EXR are not available on extend (standard dynamic range only).
