API README

LTX 2.3 22B Distilled Reference to Video

LTX 2.3 22B Distilled Reference to Video is a reference-guided video creation endpoint in the LTX 2.3 family. It is built for creators who need to turn a concrete creative brief into a controlled visual sequence: the request establishes the source material, the intended subject behavior, the camera language, and the atmosphere of the finished shot. The distilled route keeps that workflow explicit instead of hiding its input assumptions behind a generic video-generation label.

In practice, this route accepts image, video, audio, end image as creative context and exposes aspect ratio, generate audio for delivery planning. That makes it suitable for shot-based pipelines where teams must preserve a source, direct a transformation, or control the final format without losing sight of the model's central task. Write prompts as a compact shot plan—subject, action, setting, camera, light, and timing—then use the structured fields for constraints that should remain deterministic across iterations.

Highlights

Reference clip as creative anchor. The video input supplies motion or visual identity to reference while the prompt describes the intended new result.
Opening-frame guidance. An optional image can fix the generated shot’s initial appearance in addition to the reference video.
Independent sound conditioning. An optional audio input can replace or guide the soundtrack separately from the visual reference.
Distilled-route reference-strength controls. video_strength, image_strength, or audio_strength tune each conditioning channel where those fields are documented. This capability is exposed by the named distilled route and its exact request fields. For lightricks/ltx-2.3-22b-distilled/reference-to-video, this task-specific control is documented alongside the route’s own required inputs.

When to Use

Scenario	Recommendation
Choose this route	Use it when the deliverable specifically calls for reference-guided video creation, rather than a neighboring generation mode.
Prepare the source	Provide image, video, audio in the format described by the request schema.
Direct the shot	Describe the subject, action, environment, camera movement, lighting, and temporal progression in that order.
Control continuity	Use endpoint frames, reference media, strength, or audio controls when those fields are available instead of burying hard constraints in prose.
Plan delivery	Set duration, frame count, resolution, and aspect ratio explicitly when the schema exposes them, then compare iterations with a stable seed where supported.

Prompt Guide

For reference-guided video creation, describe one coherent shot rather than a list of visual keywords. Put the main subject and action first, follow with location and staging, then add camera movement, lens or framing, lighting, mood, and any timed change. Keep URLs and hard delivery choices in their dedicated fields.
