Ltx 2 19b Distilled 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 generate the video from.

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.

Video Strength(number)

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

Preprocessor(string)

The preprocessor to use for the video. When a preprocessor is used and `ic_lora_type` is set to `match_preprocessor`, the IC-LoRA will be loaded based on the preprocessor type. 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.

Image Strength(number)

The strength of the image to use for the video generation. Range: 0 to 1.

IC-LoRA(string)

The type of IC-LoRA to load. In-Context LoRA weights are used to condition the video based on edge, depth, or pose videos. Only change this from `match_preprocessor` if your videos are already preprocessed (or you are using the detailer.) Allowed values: match_preprocessor, canny, depth, pose, detailer, none.

IC-LoRA Scale(number)

The scale of the IC-LoRA to use. This allows you to control the strength of the IC-LoRA. Range: 0 to 1.

End Image Strength(number)

The strength of the end image to use for the video generation. Range: 0 to 1.

Seed(integer)

The seed for the random number generator.

Loras(array)

Enter a JSON array.

API README

LTX-2 19B Distilled

LTX-2 19B Distilled is a video transformation with custom LoRA adapters endpoint in the LTX 2 19B 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, image strength, 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

Whole-clip transformation. The video input is the visual timeline to reinterpret; the prompt specifies the desired treatment and motion outcome.
Adjustable source fidelity. video_strength balances preservation of the input clip against freedom to transform it.
Soundtrack-aware processing. Existing or supplied audio can condition the result, with audio_strength controlling its influence.
Route-specific LoRA conditioning. The loras array adds learned styling or concepts to this video to video workflow without replacing its required source inputs. For lightricks/ltx-2-19b/distilled/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 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 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.
