Introducing LTX-2 Video API on Pixazo for Unified Audio-Visual AI Video Generation

We’re excited to introduce the LTX-2 Video API on Pixazo, a next-generation multimodal AI video foundation model developed by Lightricks and now available through Pixazo’s unified API platform. Also known as LTX Video 2.0, LTX-2 represents a major advancement in AI video generation by becoming the first all-in-one model capable of generating synchronized video and audio together in a single pass.

LTX-2 API is designed for creators, developers, and production teams who need high-fidelity video output with realistic motion, cinematic structure, and native sound — without relying on fragmented pipelines for visuals, dialogue, music, and ambience. Whether you are generating videos from text prompts, animating still images, or building advanced creative applications, LTX-2 delivers production-ready results with unprecedented coherence and control.

By integrating LTX-2 into Pixazo, teams can now access text-to-video and image-to-video generation, synchronized audio, extended video durations, and native high-resolution output — all through a standardized, scalable API experience.

What Is LTX-2 Video API?

The LTX-2 Video API provides programmatic access to Lightricks’ advanced multimodal video generation model, enabling developers and platforms to generate complete videos — visuals and audio together — from either natural-language prompts or visual references.

Unlike traditional AI video systems that generate silent footage and require external audio tools for voice, music, or sound effects, LTX-2 treats audio and video as inseparable components of a single generative process. Motion, dialogue, background ambience, and music are all produced in perfect sync, ensuring that sound timing, emotional tone, and visual pacing remain aligned throughout the clip.

LTX-2 supports both:

• Text-to-Video (T2V) workflows for generating videos directly from prompts
• Image-to-Video (I2V) workflows for animating still images into coherent video sequences

Through Pixazo, these capabilities can be embedded directly into creative tools, content platforms, and automated video pipelines.

Unified Audio and Video Generation in a Single Pass

At the core of LTX-2 is a unified latent video auto-encoder combined with a spatio-temporal transformer architecture. This design allows the model to reason about motion, space, time, and sound simultaneously, rather than treating them as separate stages.

When generating a video, LTX-2 determines:

• How subjects move and interact over time
• How camera perspective and motion evolve across frames
• How dialogue aligns with mouth movement and facial expression
• How music and ambient sound support the emotional flow of the scene

Because audio is generated alongside visuals, the output feels intentionally directed rather than assembled after the fact. Dialogue timing, background ambience, and sound effects reinforce visual action, creating a cohesive cinematic experience from a single generation step.

High-Fidelity Video Output With Extended Duration Support

LTX-2 is built for longer, more coherent video generation than many earlier AI video models. Using the LTX-2-fast flow, developers can generate up to 20 seconds of continuous, synchronized audio and video in a single run.

This extended duration allows for:

• More complete narrative beats
• Meaningful camera movement and pacing
• Consistent character motion across scenes
• Audio continuity without abrupt transitions

For creators and platforms, this makes LTX-2 suitable not just for experimental clips, but for real storytelling, marketing content, and production workflows.

Native High-Resolution and Smooth Motion

LTX-2 supports native high-resolution video generation, producing outputs up to 4K (2160p) resolution with smooth motion and strong visual fidelity. The model is designed to handle complex motion dynamics while maintaining clarity across frames, reducing common AI artifacts such as jitter, distortion, or inconsistent movement.

With support for high frame rates and refined temporal consistency, LTX-2 produces videos that feel fluid and visually grounded — even in scenes with camera movement, character motion, or environmental effects.

This makes the model well-suited for:

• Social media and short-form content
• Marketing and branded videos
• Cinematic concept previews
• Research and experimental video generation

Text-to-Video Generation With Natural Language Control

In text-to-video mode, LTX-2 translates natural-language prompts into visually rich, motion-aware video sequences. Prompts can describe not only what appears in the scene, but also how it unfolds over time.

The model understands:

• Scene composition and environment
• Camera logic and movement
• Emotional tone and pacing
• Interaction between subjects

By combining linguistic reasoning with temporal understanding, LTX-2 generates videos that follow creative intent rather than producing disconnected visuals.

Image-to-Video Generation With Coherent Motion

The LTXV 2.0 image-to-video model allows users to animate still images into realistic video sequences. Instead of simply applying motion effects, the model analyzes spatial structure and visual context to generate believable movement.

This approach enables:

• Natural subject motion
• Stable background behavior
• Consistent lighting and perspective
• Smooth transitions across frames

Because the same spatio-temporal transformer is used, the output maintains coherence even as motion complexity increases.

Advanced Creative Control for Professional Workflows

LTX-2 offers a wide range of advanced control features designed for professional and research use cases. These include:

• Multi-keyframe conditioning, allowing creators to guide motion and structure across time
• 3D camera logic, enabling realistic camera movement and spatial reasoning
• LoRA fine-tuning support, making it possible to maintain stylistic consistency across generations
• Flexible input combinations, mixing text, images, and conditioning data

These capabilities make LTX-2 far more than a basic video generator — it functions as a flexible video foundation model that can adapt to diverse creative and technical requirements.

Model Variations for Speed, Quality, and Cinematic Fidelity

LTX-2 is available in three specialized flows, each optimized for different production needs:

1. LTX-2 Fast

Designed for rapid iteration and brainstorming, this flow generates high-quality previews quickly. It is ideal for testing concepts, prototyping scenes, or running high-volume generation tasks.

2. LTX-2 Pro

The balanced production standard, offering strong visual fidelity, reliable motion, and efficient performance. This mode is well-suited for social media content, ads, and branded video workflows.

3. LTX-2 Ultra

Built for maximum cinematic quality, this flow prioritizes texture, detail, and realism. It is designed for high-end creative work such as film concepts, VFX previews, and premium storytelling.

This tiered approach allows teams to choose the right balance between speed and visual quality based on their use case.
