lightricks/ltx-0.9.7-13b-distilled

Ltx 0.9.7 13b Distilled is Lightricks's text-to-video AI model. Turn written scripts and prompts into professional-quality video clips with realistic motion, lighting, and scene composition.

Input
Text prompt to guide generation
The aspect ratio of the generated image. Allowed values: 21:9, 16:9, 3:2, 4:3, 5:4, 1:1, 4:5, 3:4, 2:3, 9:16.
Resolution of the generated video. Allowed values: 480p, 720p.
Random seed for generation
212
Number of inference steps during the second pass. Range: 2 to 12.
Whether to use a detail pass. If True, the model will perform a second pass to refine the video and enhance details. This incurs a 2.0x cost multiplier on the base price.
160
The frame rate of the video. Range: 1 to 60.
212
Number of inference steps during the first pass. Range: 2 to 12.
91441
The number of frames in the video. Range: 9 to 1441.
LoRA weights to use for generation
01
The factor for adaptive instance normalization (AdaIN) applied to generated video chunks after the first. This can help deal with a gradual increase in saturation/contrast in the generated video by normalizing the color distribution across the video. A high value will ensure the color distribution is more consistent across the video, while a low value will allow for more variation in color distribution. Range: 0 to 1.
111
The number of inference steps to skip in the initial steps of the second pass. By skipping some steps at the beginning, the second pass can focus on smaller details instead of larger changes. Range: 1 to 11.
01
The compression ratio for tone mapping. This is used to compress the dynamic range of the video to improve visual quality. A value of 0.0 means no compression, while a value of 1.0 means maximum compression. Range: 0 to 1.
Whether to expand the prompt using a language model.
Whether to reverse the video.

API README

LTX Video-0.9.7 13B Distilled

LTX Video-0.9.7 13B Distilled is a Ltx 0.9.7 13B Distilled endpoint in the LTX Video 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 loras as creative context and exposes num frames, resolution, aspect ratio 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

  • Cinematic video synthesis. LTX Video combines prompt direction with temporal generation for coherent shots.
  • Adapter-based styling. LoRA inputs let teams layer specialized looks or learned concepts onto the base generation path.
  • Resolution-aware delivery. Explicit output resolution lets the request target preview or finishing needs before generation.
  • Controllable shot length. Duration or frame-count controls make timing an explicit part of the generation brief.

When to Use

ScenarioRecommendation
Choose this routeUse it when the deliverable specifically calls for Ltx 0.9.7 13B Distilled, rather than a neighboring generation mode.
Prepare the sourceProvide a precise written brief in the format described by the request schema.
Direct the shotDescribe the subject, action, environment, camera movement, lighting, and temporal progression in that order.
Control continuityUse endpoint frames, reference media, strength, or audio controls when those fields are available instead of burying hard constraints in prose.
Plan deliverySet 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 Ltx 0.9.7 13B Distilled, 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.

{
  "prompt": "A cinematic fast-tracking shot follows a vintage, teal camper van as it descends a winding mountain trail. The van, slightly weathered but well-maintained, is the central focus, its retro design emphasized by the motion blur. Medium shot reveals the dusty, ochre trail, edged with vibrant green pine trees. Close-up on the van's tires shows the gravel spraying, highlighting the speed and rugged terrain. Sunlight filters through the trees, casting dappled shadows on the van and the trail. The background is a hazy, majestic mountain range bathed in warm, golden light. The overall mood is adventurous and exhilarating. High resolution 4k movie scene.",
