Made with this app
How it works
LTX-2 Pro by Lightricks brings high-resolution AI video generation up to 4K (2160p) to creators who refuse to compromise on visual fidelity. Built for social content producers, commercial teams, and directors who need sharp, detailed footage fast, this app pairs that resolution ceiling with native synchronized audio, meaning your generated clips arrive ready to use rather than requiring a separate audio pass. Text prompts and image inputs both work as starting points.

What you can make
Product Launch Campaigns
Brand teams can generate 4K product showcase clips with synchronized audio cues, sharp material textures, and cinematic framing. The 2160p ceiling means the footage holds up on large-format displays and retains quality after export compression, reducing post-production overhead for commercial deliverables.
Social Reels at Maximum Quality
Platforms like YouTube and Instagram now surface 4K content prominently. LTX-2 Pro lets creators generate short, visually dense clips at 1440p or 2160p that stand out in feeds, with native audio already in sync so ambient sound, music texture, or environmental noise does not need to be added separately.
Image-to-Video for Photography
Photographers and visual artists can feed a single still image into LTX-2 Pro and receive a sharp, motion-extended clip. Because the model preserves fine detail, intricate textures such as fabric weave, foliage, or architectural surfaces remain legible throughout the generated motion.
Pre-Visualization for Directors
Filmmakers can rapid-prototype scene ideas as 4K clips before committing to a shoot. The combination of high resolution and synchronized audio gives directors a pre-vis that communicates lighting mood, camera movement, and sound design intent to crew members far more clearly than static boards.
High-Fidelity Ad Creative Testing
Marketing teams running A/B tests on ad creative can use LTX-2 Pro to generate multiple 4K video variants from text descriptions, evaluate visual and audio performance, and shortlist concepts before investing in live production. The native audio layer makes each variant feel finished enough for honest audience feedback.
Prompt ideas to try
- A luxury watch rotating slowly on a black marble surface, water droplets scattering across the case, close-up macro lens, crisp studio lighting, ambient metallic resonance in the audio.
- Aerial tracking shot over a dense rainforest canopy at golden hour, light filtering through mist, birds lifting from the treetops, natural ambient jungle soundscape synchronized to motion.
- A chef plates a dish in a modern open kitchen, steam rising from the food, tight focus on hands and ingredients, soft clatter of ceramic synchronized with each motion.
- Abstract fluid simulation where crimson and cobalt ink diffuse through clear water in slow motion, ultra-sharp particle detail, low resonant drone audio pulsing with the color movement.
- A mountain trail runner cresting a ridgeline at sunrise, breath visible in cold air, wide landscape behind her, footsteps and wind synchronized naturally to each stride.
- Futuristic urban skyline at night with neon reflections on wet pavement, a single autonomous vehicle gliding silently past, rain audio and distant city hum layered in the background.

Tips for better results
Specify Audio Character Explicitly
LTX-2 Pro generates native synchronized audio from your text prompt. Include sound descriptors such as ambient room tone, material-specific sounds, or environmental conditions. The more specific your audio language, the more coherent the synchronized result across the full clip duration.
Choose Resolution to Match Output Destination
The app offers 1080p, 1440p, and 2160p. Select 2160p when the final destination is a large display, broadcast context, or platform that rewards high resolution. Use 1440p for social reels where file size matters. Matching resolution to destination avoids unnecessary credit spend on upscaling later.
Anchor Image Inputs with Strong Composition
When using image-to-video mode, start with a source image that already has clear focal depth and subject separation. LTX-2 Pro preserves sharp detail from the input, so a well-composed still produces motion that reads cleanly at 4K rather than amplifying any softness present in the original.
Use the 6-to-10 Second Range Strategically
Clips run between 6 and 10 seconds. For narrative impact, structure your prompt around a single clean action or transition that resolves within that window. Prompts that describe multiple sequential events risk crowding the timeline and producing abrupt cuts rather than smooth, purposeful motion.
When to choose this app
Choose LTX-2 Pro when your primary requirement is the highest available resolution combined with native synchronized audio in a single generation pass. Compared to Seedance 2.0 Mini, which targets speed and lightweight output, or Pika 2.2, which emphasizes stylized aesthetics, LTX-2 Pro is the right tool when a client or platform demands 4K fidelity and the audio layer cannot be an afterthought. It suits commercial briefs where visual sharpness and sound are both non-negotiable.
Frequently asked questions
What does native synchronized audio actually mean in practice?
Rather than generating a silent video that you later pair with a separate audio file, LTX-2 Pro produces audio as part of the same generation pass. The sound is timed to the visual motion described in your prompt, so footsteps, ambient environments, or material sounds align with what is happening on screen without manual editing.
Can I use an existing image as the starting point instead of a text prompt?
Yes. The app accepts both text and image inputs. You can upload a photograph, illustration, or rendered still and the model will generate motion extending from that composition, preserving the sharp detail and color information present in your source image throughout the clip.
How does LTX-2 Pro handle fine visual detail at 4K compared to lower resolutions?
At 2160p, the model has significantly more pixel density to work with, so textures such as fabric, skin pores, foliage, or reflective surfaces remain legible rather than blurring into noise during motion. If fine-grained material or surface detail matters to your output, generating at 2160p rather than 1080p produces a meaningfully sharper result.
Is a 6 to 10 second clip long enough for professional use cases?
For most social formats, ads, product showcases, and pre-visualization purposes, yes. A single focused concept, one camera move, or one product interaction fits comfortably within 10 seconds. For longer narratives, creators typically generate multiple clips and edit them together in a standard video editing application.
Does the quality of my text prompt significantly affect the output at 4K?
Substantially. At higher resolutions the model renders more detail, which means vague prompts can produce technically sharp but visually ambiguous results. Prompts that specify lighting quality, surface materials, camera distance, and audio character give the model enough information to fill that resolution with purposeful, coherent visual and sonic content.
What types of motion work best with LTX-2 Pro given its sharp detail focus?
Controlled, deliberate motion tends to showcase the model's strengths most effectively. Slow reveals, single-axis camera moves, product rotations, and environmental ambient motion such as steam, water, or wind all benefit from sharp rendering. Rapid chaotic motion can limit how much fine detail the model can maintain frame to frame.
Which AI model powers this app?
This app runs on LTX-2 Pro, available through Arteza with no separate account or setup.
Can I use the results commercially?
Yes. Content you generate is yours to use, subject to our content licenses.
How long does a generation take?
Most generations finish in under a minute, and you can watch progress live in the gallery.
