LTX AI models: from fast iteration to finished shots

LTX AI video models by Lightricks turn text prompts and still images into short video clips. Choose from models built for rapid iteration or precise, finished output, with native audio, start/end frame control, and cinematic motion across the whole family.

What are LTX AI video models?

LTX AI video models are Lightricks' video generation models, available inside Artlist's AI tools. They turn text prompts and images into short-form clips, prioritizing speed and stylized motion over photorealism. Artlist offers the LTX models themselves, not Lightricks' LTX Studio platform.

How LTX AI models actually generate video for you

The LTX models handle the core video generation loop: text-to-video, image-to-video, start/end frame control, scene extension, and audio-driven generation. Understand what each mode does well (and where it needs more from you) to get that usable clip.

  • Build a scene from a prompt

    Describe a scene, and LTX builds it. Angles, subject behavior, and lighting all respond to prompt direction. LTX rewards clear prompts over long ones. Subject, setting, motion, camera, and tone matter most. Miss one, and the model fills the gap. More on structuring prompts in the tips section below.

  • Animate any still frame

    LTX animates uploaded images, adding motion to existing compositions instead of rebuilding the scene from scratch. Works well with concept art, portraits, and photography. The stronger the input, the stronger the output.

  • Start and end frame control

    Make a character’s expression change or a car drive down the road with a start and end frame. LTX generates the transition between them. A fast way to prototype controlled visual sequences. Just make sure the two frames are compatible. Dramatic changes in layout or subject produce drifting.

  • Extend clips or refine specific moments

    Push a clip forward from where it ends, or replace audio, video, or both within a defined section. Both tools are for refining, not rebuilding. Narrow the window and be explicit about what stays the same. The model will drift if given too much room.

  • Audio-driven generation

    Describe a scene with a text prompt, or let an audio input steer the visuals directly. Audio-to-video mode uses the length and pacing of the audio to shape the output. Useful when you're working with a specific soundtrack or voiceover.

What can you create with LTX AI video models?

LTX is a strong fit for stylized, short-form work where motion quality matters most. These are the project types it handles best.

  • Cinematic scene animation

    Take a concept art frame or character portrait and animate it into a clip. The more behavior you describe, the less the model fills in with something generic.

  • Pre-visualization and concept animation

    Concept frames can be animated for pitch decks, pre-vis reels, or client presentations. LTX adds motion to the existing composition, which keeps the framing and mood close to the original.

  • Environmental and atmospheric animation

    Photos of landscapes and architecture animate well. The more precise your prompt, the more intentional the output looks.

LTX 2.5 fast

LTX 2.5 Fast text-to-video built for rapid iteration

LTX 2.5 Fast 1080p generates clips in 6 to 20 seconds, so you can test prompts and find your direction before committing to a longer render. Output scales from 720p to 4K at 24, 25, 48, or 50 fps, covering cinematic and broadcast frame rates. Lock in your concept here, then move to a slower model for the final output.

How to use LTX AI video models in Artlist

LTX AI video models work inside Artlist's AI tools, not in a separate LTX app. Here's how to get from the AI tools to a finished clip.

  • Open the AI tools

    In Artlist, navigate to the AI tools from the main menu. This is where all its video, image, and audio tools sit in one place.

    How to use LTX Studio AI in Artlist - step 1

  • Select video generation and choose your LTX model

    Find the video generation toggle inside the AI tools and open the models menu. Select LTX. If you’re unsure which mode to use, pick based on what input you already have.

    How to use LTX Studio AI in Artlist - step 2

  • Add an image, prompt, or both

    For image-to-video, upload your start frame. For transitions, add a start and end image. For text-to-video, use this formula: [Subject], [action], [environment], [camera motion], [lighting/mood].

    How to use LTX Studio AI in Artlist - step 3

  • Generate and download

    Generate your base clip. Preview it. Download the finished file directly from the AI tools when it’s ready.

The limits you might run into with LTX AI models

  • Built for short-form, 20 seconds is the ceiling

    Each generation runs 6, 8, or 10 seconds, but you can also extend clips to 20. The model can’t generate any further beyond that. If your project needs longer sequences, plan to build in segments and edit them together. LTX is a clip generator, not a long-form production tool.

  • Audio input has a strict window

    Audio-to-video mode accepts files between 2 and 20 seconds only. Outside that range, recordings won’t process. Trim your audio before uploading. The model uses the full audio clip to steer visuals, so the length and pacing of the audio directly shapes the output.

  • Two aspect ratios, nothing in between

    LTX supports 16:9 and 9:16. No 1:1, 4:3, or custom ratios. For image-to-video, the aspect ratio is detected automatically from the input. So whatever you upload sets the output format. If you need a different ratio, crop the output in post.

  • Be careful on plain backgrounds

    On clean, minimalist backgrounds, LTX can pull toward generic training data, introducing unwanted textures or visual noise. Add a negative constraint to your prompt: “no text artifacts, no logos, no visual noise” to keep the output clean. It won't eliminate the issue entirely, but it reduces it.

How to get better results with LTX AI models

Prompt structure, input quality, camera direction, and guidance scale. These four variables change what comes back more than anything else.

  • Describe how the scene evolves

    Static descriptions produce static-feeling clips. “A warrior stands in a storm” tells the model a state. “The warrior’s eyes begin glowing, electricity spreads across his face and shoulders, lightning bursts outward at the peak” tells it a sequence. Build change into the prompt from the start.

  • Camera motion before feelings

    Put camera motion early in the prompt. It has more influence over the overall feel of the clip when it appears at the front. “The camera slowly pushes in from a side profile” works. “Dynamic camera” doesn’t. If you don’t specify a move, the model will choose one for you.

  • Adjust guidance scale

    LTX has a guidance scale that dictates how strictly the model follows your prompt. In Artlist, it defaults to 5 for text-to-video and 9 for image-based generation. If the output isn’t following your prompt closely, increase it. And bring it down if it’s over-fitting and losing motion fluidity.

  • Describe what happens next

    If you want to extend a scene by another 20 seconds, your prompt should describe the next steps of the scene, not re-describe what’s already happened.

Who are LTX AI video models best for?

LTX AI video models suit projects where iteration speed and motion quality are key. Here's who tends to get the most from them, and what that actually looks like in practice.

    LTX generates fast to test various directions for product teasers and social content. Works best for cinematic content, not the documentary-realistic kind.

Frequently asked questions

LTX AI models are available inside Artlist's AI tools. Select the video generator mode, choose an LTX model, and add your input (a text prompt, a still image, or both). Depending on the model, clips generate in 6 to 20 seconds. From there, you can extend the clip up to 20 seconds, replace or refine specific sections with Retake, or download the finished file directly. The whole loop (generate, review, iterate) runs inside the AI tools without switching tools.

No. LTX Studio is Lightricks' own AI video production platform, and it is not part of Artlist. What Artlist offers are the LTX models that power it: LTX 2.5 Fast 1080p, LTX 2.5 Pro, and LTX 2.3 Pro, running inside Artlist's AI tools alongside models from Kling, Veo, Hailuo, Seedance, and others. You get LTX generation, extension, and audio-driven modes without leaving your Artlist workflow.

Three LTX models are currently available in Artlist: LTX 2.5 Fast 1080p, built for rapid iteration at 6 to 20 seconds; LTX 2.5 Pro, for cinematic output with native audio and start/end frame control; and LTX 2.3 Pro, Lightricks' previous flagship for fast, stylized generation. As new models are released, this page will be updated.

LTX is built for speed and stylized motion. Where it performs best:

  • Fast iteration. Test motion, camera moves, and scene dynamics without long render times
  • Cinematic movement and atmospheric effects
  • Image-to-video animation that preserves the source composition
  • Camera instruction following and prompt adherence. What you specify tends to show up in the output.

Where LTX runs into issues: 

  • Strict photorealism isn’t what this model is built for. 
  • On plain or minimal backgrounds, the output can pull toward generic training data, adding unwanted textures or visual noise. 
  • Over extended clips, character consistency can drift between frames.
  • If your prompt is vague, the model fills the gaps on its own terms, which is where outputs start to feel generic.

In practice, LTX AI’s short-form video output covers a wide range of creative work:

  • Animated concept art and character portraits
  • Pre-vis and pitch reels for film and creative projects
  • Product teasers and social content in portrait or landscape
  • Atmospheric scene animation, such as landscapes, architecture, environmental stills
  • Controlled visual transitions between two defined states

If you want something with a similar feel to LTX (fast generation and stylized output), Hailuo 2.3 Fast Pro and Kling 2.5 Turbo Pro are the closest in the AI tools. Both prioritize speed and work well for iterative, motion-rich work.

If LTX’s stylized output or 20-second ceiling is the limitation, Veo 3.1 is worth looking at. Veo 3.1 is the strongest option for photorealistic output.

For overall creative range, Kling 3.0 and Wan 2.7 are two of the most capable all-round models available. Both handle a wider variety of styles and briefs than LTX is designed for.

LTX models are developed by Lightricks, an AI company focused on creative tools. Lightricks builds its models in-house. LTX Video is their open-source video model, and LTX Studio is Lightricks' own platform built around it. Artlist integrates the LTX models directly into its AI tools; the LTX Studio platform itself is not available in Artlist. Lightricks' wider product portfolio includes Facetune, Videoleap, and Photoleap.
