LTX-2 is best when you want strong quality (up to 4K, with audio) without long render times or high cost.
Background. Lightricks open-sourced LTX-2 in January 2026 as a production-ready foundation model that generates synchronized audio and video — up to 4K — with truly open weights.
Open Vivideo and start a new video.
Select LTX-2 as your model — or let the Video Agent pick it for you.
Describe your shot (or upload an image) and set duration and aspect ratio.
Generate with LTX-2, then refine, add a voice or avatar, and export for any platform.
Each model is one of 30+ in Vivideo — switch per shot to get exactly the look you want.





State-of-the-art motion, realism and native audio.



LTX-2, from Lightricks, is an efficient model offering high-resolution output with audio at speed. It balances quality and turnaround well.
LTX-2 suits creators who need good-looking video fast and at volume — social, ads and iterative work where you generate many takes. Its efficiency keeps the creative loop tight.
Vivideo bundles LTX-2 with 30+ models on one plan, so you can iterate quickly on LTX-2 and switch to a heavier model only for final hero shots — no separate Lightricks subscription.
LTX-2 is the efficiency play among top-tier models: up to 4K with native synchronized audio, clips up to about 20 seconds, and render speeds that keep an iteration loop tight. LTX-2 text to video pairs open weights with transparent per-second pricing, and the model is fine-tunable with LoRA support — which is why studios wire it into local and on-prem pipelines.
Its constraints are practical rather than fatal: the license is open-weight but not fully permissive (a commercial threshold applies), and generation has dimension and frame-count rules to plan around. LTX-2 image to video shares the same speed advantage. Against Veo 3.1 it trades a little peak polish for far cheaper 4K volume — the right call for series content, ads at scale and fast client turnarounds.
On Vivideo, an LTX-2 AI video is free to try — daily free generations, no Lightricks account or ComfyUI setup. A high-volume pattern that works: iterate takes on LTX-2 at speed, lock the winners, reserve a premium engine for the single hero shot, then cut everything together with captions and voiceover into an edit of up to 10 minutes.
You can try LTX-2 free on Vivideo to start — no credit card. Heavier use and premium models are covered by a paid plan.
Yes — LTX-2 can output up to 4K with native audio while staying fast and affordable, a strong all-rounder.
Yes — on Vivideo you can use LTX-2 for both text-to-video and image-to-video, and switch to other models per shot.
Yes — its speed and cost make LTX-2 well suited to producing a lot of video efficiently.
Base clips run up to about 20 seconds — long by current standards. For full videos, chain LTX-2 shots in Vivideo into edits of up to 10 minutes.
It's open-weight under the LTX-2 Community License — free to run and fine-tune, with a commercial threshold above which a license is required. On Vivideo you use it with no setup at all.
