LTX Video 2.3 Full Quality is Lightricks' open-weights, diffusion-based AI model that generates synchronized video and audio from text, images, or audio input. Released March 5, 2026, it supports up to 20-second clips in 4K, native portrait aspect ratios, and HDR output via LoRA, with improved fine detail and motion coherence over its predecessor.
Use LTX Video 2.3 Full Quality privately on Venice
On Venice, LTX Video 2.3 Full Quality runs under an anonymized privacy tier — your prompts are not stored, profiled, or used for training. This means you can generate commercial-grade video content with full sovereignty, knowing your creative concepts remain private. The model's open weights and uncensored nature allow for permissionless innovation, whether you're building branded content or experimental media.
What can LTX Video 2.3 Full Quality do?
- •Open weights enable local execution, fine-tuning, and full ownership of output — rare among high-fidelity video models.
- •Native portrait generation (up to 1080×1920) trained on vertical data, not cropped from landscape — ideal for social media workflows.
- •Synchronized audio generation where voice, music, and sound effects shape motion and pacing — not added in post.
- •Improved spatial intelligence and motion coherence, with sharper fine detail thanks to a rebuilt VAE and latent space.
- •Strong prompt adherence with a 4x larger text connector, handling complex prompts involving multiple subjects and spatial relationships.
- •Complex physics (e.g., water, crowds) and emotional tonal subtlety still lag behind top closed models like Kling 3.0 or Runway Gen-4.5.
- •Image-to-video mode can exhibit instability in current release, requiring careful prompt engineering or retakes.
- •Limited to 10-second clips at 1440p/4K in Pro tier; 20-second generation only available at 1080p.
- •No end-to-end encryption or TEE protection on Venice — privacy is anonymized, not fully secured.
Sample outputs
Generated on Venice with our standard prompt suite — the same prompts we run through every model of this type, so you can judge it like-for-like.
Slow aerial drone shot gliding over a misty mountain valley at golden hour, sunlight piercing clouds onto a winding river, ancient pine forests on either side, ultra-smooth motion, professional color grading, atmospheric haze, 4K
Calm ocean waves rolling onto a black-sand beach at sunrise, golden light on wet sand, foam dissolving into the shore, a single silhouetted figure at the waterline, smooth continuous forward push, serene cinematic atmosphere
A slow tracking shot through a rain-soaked Tokyo street at night, neon reflecting in puddles, steam rising from a food cart, a person with a translucent umbrella, shallow depth of field, teal-and-orange grade, smooth steady camera
LTX Video 2.3 Full Quality model variants
LTX Video 2.3 Full Quality runs on Venice as 2 variants of the same underlying model — pick by what you're starting from: a written prompt, a still image, reference images, or an existing clip. Each variant is its own model id on the API; the generation quality is the same across the family.

Prompting tips
- •Use clear spatial and stylistic descriptors — 'a woman in red dress on left, city skyline on right' — to leverage improved prompt adherence.
- •For portrait content, specify 'vertical video' or '9:16 aspect ratio' to ensure native generation.
- •Use HDR LoRA for grading-ready EXR output if post-production flexibility is needed.
- •For audio-to-video, provide clean audio input with clear pacing cues to maximize visual synchronization.
