API README

LTX 2.3 22B Video to Video

LTX 2.3 22B Video to Video is a video transformation 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 standard route keeps that workflow explicit instead of hiding its input assumptions behind a generic video-generation label.

In practice, this route accepts video 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

  • Whole-clip transformation. The video input is the visual timeline to reinterpret; the prompt specifies the desired treatment and motion outcome.
  • Adjustable source fidelity. The source video remains the temporal basis while the prompt changes its rendition.
  • Soundtrack-aware processing. generate_audio determines whether sound is produced with the transformed clip.
  • LTX 2.3 22B endpoint framing. Aspect ratio provides an explicit delivery frame for the transformed video. This behavior is exposed on the named 22B route. For lightricks/ltx-2.3-22b/video-to-video, this task-specific control is documented alongside the route’s own required inputs.

When to Use

ScenarioRecommendation
Choose this routeUse it when the deliverable specifically calls for video transformation, rather than a neighboring generation mode.
Prepare the sourceProvide video 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 video transformation, 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.
