Generate with LTX-2 Pro — high-fidelity 4K AI video
LTX-2 Pro (LTX 2.0 Pro) is the high-fidelity variant of Lightricks' open-source LTX-2 video model — up to native 4K, sharper detail and stronger motion coherence than LTX-2 Fast. On this site it powers our Pro and Ultra generation modes.
LTX-2 Pro vs LTX-2 Fast
Both checkpoints come from the same open-source LTX-2 family — the difference is what they optimize for.
Fidelity first — built for final renders
- Sharper textures and finer detail
- Better motion coherence across frames
- Up to native 4K (2160p) output
- Pro mode: 1.5x credits · Ultra mode: 2.0x credits
Speed first — built for drafts and iteration
- Quickest turnaround per generation
- Great for prompt exploration and previews
- 1080p-class output for rapid drafts
- Fast mode: 1.0x credits — lowest cost
A common workflow: iterate on your prompt in Fast mode, then re-render the winning take with LTX-2 Pro (or Ultra for forced 4K with audio) for the final version.
When to use LTX-2 Pro
Reach for Pro whenever the output is the deliverable — not just a draft.
Final renders
Once a prompt works, render the definitive version with LTX-2 Pro — cleaner edges, stable motion and up to 4K resolution that holds up on large screens.
Client work
Deliverables for clients need to survive scrutiny. Pro's higher fidelity and consistent detail make it the safe default for agency and freelance output.
Marketing content
Ads, product teasers and social campaigns compete on polish. LTX-2 Pro with synchronized audio produces publish-ready clips in a single generation.
Cinematic shots
For film-style sequences, use Ultra mode — it runs LTX-2 Pro at forced 4K with synchronized audio for maximum visual and sonic fidelity.
