# LTX Canonical page: https://fuser.studio/models/ltx LTX in Fuser generates short video from a text prompt at up to 720p, fast enough for quick motion tests. Upgrade shots to LTX 2.0 on the same canvas. ## Specs | Spec | Value | | --- | --- | | Inputs | Prompt (text), Negative Prompt (text) | | Output | video | | Resolution | 480p, 720p | | Aspect ratios | 16:9, 9:16 | | Cost | 55 credits per run | Instant cinematic video synthesis with fluid camera sweeps and natural physical momentum Creator: Lightricks Also known as: LTX [Synthesize Video](https://app.fuser.studio) ## How LTX works Three streamlined stages to take your cinematic concepts from text descriptions to real-time generated video clips. ### Describe Scene and Lighting Compose your scene in present-tense sentences, establishing subject motion, material textures, and natural lighting cues. ### Set Camera and Quality Controls Select 16:9 or 9:16 aspect ratios, define dolly or tracking camera paths, and set steps from 20 for drafts up to 50 for final polish. ### Generate Fluid Video Footage Synthesize video frames in real time with believable physical weight, organic motion blur, and cinematic depth. ## What LTX is good at Explore the architectural breakthroughs, motion responsiveness, and granular generation controls that power LTX-Video. ### Real-Time Latent Transformer Architecture Powered by a latent diffusion transformer with a 1:192 Video-VAE compression ratio, generating video frames at sub-second speeds for immediate creative feedback loops. ### Cinematographic Camera Control Direct fluid dolly sweeps, pans, and tracking shots that maintain physical momentum, natural atmospheric lighting, and organic depth across 16:9 and 9:16 aspect ratios. ### Adaptive Step and Resolution Scaling Scale inference steps between 20 for instant rough-cut storyboards and 50 for refined, artifact-free 720p footage with rich filmic grain and volumetric lighting. ### Configurable Script and Prompt Expansion Toggle built-in prompt expansion to enrich simple concepts with atmospheric nuance, or disable it to execute exact screenplay-style framing without interference. ## Made with LTX A gallery of real-time cinematic sequences demonstrating dynamic camera sweeps, natural lighting interactions, and distinct stylistic aesthetics. ### Atmospheric architectural exploration ### High-impact brand motion frame ### Modern lookbook motion vignette ### Dramatic soundstage concept ### Vertical fashion movement study ## What people build with LTX How directors, visual designers, and creative teams deploy LTX-Video for rapid storyboarding, campaign prototyping, and visual development. ### Cinematic Pre-Visualization and Storyboarding Iterate on complex multi-shot cinematic blocking and camera sweep drafts in real time without waiting on lengthy render queues. ### Fashion Editorial Motion Design Produce striking lookbook video snippets and fabric motion studies with rich natural lighting and editorial depth. ### Industrial and Automotive Concepting Evaluate dynamic product silhouettes, surface finishes, and automotive forms using fast orbit and tracking sweeps. ### Advertising Campaign Concepting Draft commercial hero moments and social campaign vignettes with vivid color tension and polished physical motion. ### Documentary and World-Building Drafts Generate atmospheric narrative scenes and period-accurate historical textures for early-stage pitch decks. ## Frequently Asked Questions ### Is LTX the same as LTX-Video? LTX is the common shorthand for LTX-Video, an open-weights latent diffusion transformer model developed by Lightricks for real-time video generation. Both names refer to the same architecture. ### How fast is video generation with LTX-Video? LTX-Video delivers near-instantaneous video synthesis, generating video clips faster than playback speed on high-end hardware. Its specialized Video-VAE uses a 1:192 compression ratio (32x32x8 spatiotemporal downscaling), allowing creators to iterate on cinematic motion concepts in real time. ### How many inference steps should I use for optimal quality? Use 20 to 30 inference steps for ultra-fast concept prototyping and rapid storyboarding drafts. For final production deliveries with refined textures and reduced visual artifacts, increase the step count to 40 or 50. ### What is the best prompt structure for LTX-Video? Write continuous present-tense natural language paragraphs under 200 words, explicitly naming camera moves such as slow dolly pans, tracking shots, or tilts with clear ending states. Avoid comma-separated quality tags like "4k" or montage instructions like "cut to", which cause frame jumps. ### When should I enable prompt expansion? Enable prompt expansion when submitting short, simple concepts so the built-in language processor can elaborate lighting and motion details. Disable it when providing exact screenplay-style instructions or precise camera angles to prevent modifications to your shot plan. ### Who created LTX-Video and when was it released? LTX-Video was developed by Lightricks in partnership with Shutterstock and released on November 21, 2024 as an open-weights model. ## Try LTX on Fuser Instant cinematic video synthesis with fluid camera sweeps and natural physical momentum [Synthesize Video](https://app.fuser.studio) ## Related models - [LTX 2.5](https://fuser.studio/models/ltx-2-5.md) - [MiniMax H3 Recast](https://fuser.studio/models/minimax-h3-recast.md) - [Kling O3 Edit](https://fuser.studio/models/kling-o3-edit.md) - [Kling O3](https://fuser.studio/models/kling-o3.md) - [Kling 3.0 Video](https://fuser.studio/models/kling-3-0-video.md) - [Seedance 2](https://fuser.studio/models/seedance-2.md) Node reference: [LTX docs](https://docs.fuser.studio/docs/nodes/video/ltx.md)
