LTX 2.0 Pro Audio to Video
LTX 2.0 Pro Audio to Video is a audio-guided video creation endpoint in the LTX 2.0 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 production route keeps that workflow explicit instead of hiding its input assumptions behind a generic video-generation label.
In practice, this route accepts image, audio as creative context and exposes focused generation controls 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
- Audio-led timing. Uses the supplied soundtrack as a temporal signal while the prompt and opening image establish the visible scene.
- Synchronized audio path. Audio conditioning or generation is available in the same request, helping sound and picture share one creative plan.
- Temporal coherence. The LTX 2.0 generation path is designed around continuous motion across a shot, not a collection of unrelated frames.
- Production iteration. Seed and sampling controls support repeatable comparisons when refining motion, framing, and visual treatment.
Pricing
The request price is calculated with params.duration * 0.10.
| Configuration | Price |
|---|---|
| Formula-priced request | params.duration * 0.10 |
The model card records a base price of $0.100000; the formula above determines usage-priced requests.
When to Use
| Scenario | Recommendation |
|---|---|
| Choose this route | Use it when the deliverable specifically calls for audio-guided video creation, rather than a neighboring generation mode. |
| Prepare the source | Provide image, 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 audio-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.
