Ltx 2.3 22b Distilled Reference Video To Video is Lightricks's video-to-video AI model. Transform, enhance, and edit video content using text prompts - from style changes to object manipulation and scene modification.

Input

Prompt(string)

The prompt to generate the video from.

Image URL or upload(string)

Upload

PNG, JPEG, WebP, or GIF · 20 MiB maximum

An optional URL of an image to use as the first frame of the video.

This field is required.

Image URL or upload(string)

Upload

PNG, JPEG, WebP, or GIF · 20 MiB maximum

The URL of the image to use as the end of the video.

Video URL(string)

The URL of the video to reference.

Audio URL(string)

An optional URL of an audio to use as the audio for the video. If not provided, any audio present in the input video will be used.

Generate Audio(boolean)

Whether to generate audio for the video.

Preprocessor(string)

The preprocessor to use for the generation. Allowed values: depth, canny, pose, none.

Audio Strength(number)

Audio conditioning strength. Lower values represent more freedom given to the model to change the audio content. Range: 0 to 1.

IC-LoRA Type(string)

The IC LoRA type to use for the generation. Allowed values: match_preprocessor, union, detailer, none.

Video Strength(number)

Video conditioning strength. Lower values represent more freedom given to the model to change the video content. Range: 0 to 1.

Seed(integer)

The seed for the random number generator.

Loras(array)

Enter a JSON array.

Async Workflow

This model uses asynchronous execution. Submit a request and poll for the result.

Submit — POST to /v1/run, receive an id
Poll — GET /v1/run/{id} until status is completed, failed, or timeout
Retrieve — Read outputs from the completed response

API README

LTX-2.3 22B Distilled

LTX-2.3 22B Distilled is a reference-video transformation with custom LoRA adapters 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, LoRA-enabled 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, loras as creative context and exposes generate audio, video strength 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.
Route-specific LoRA conditioning. The loras array adds learned styling or concepts to this reference video to video workflow without replacing its required source inputs. For lightricks/ltx-2.3-22b/distilled/reference-video-to-video/lora, 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-video transformation with custom LoRA adapters, 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-video transformation with custom LoRA adapters, 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.
