Use the LTX-2 AI video generator for high-volume, cost-efficient work: many ad variants, localized cuts and fast 4K drafts. LTX-2's open weights, speed and low price make it ideal when you need a lot of video, quickly.
Background. LTX-2 is developed by Lightricks and released under the LTX-2 Community License with open weights. It's popular for fast, affordable 4K generation and ComfyUI pipelines. On Vivideo the LTX-2 AI video generator runs online with no setup, GPUs or weight management.
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.
Vivideo puts Lightricks' open-weights LTX-2 in your browser with no ComfyUI, no GPUs and no setup. Generate LTX-2 videos from text or image prompts in up to 4K with audio, and export them watermark-free.
LTX-2 sits beside 30+ other AI video models on Vivideo, so you can run high-volume LTX-2 renders, switch to Sora 2 or Veo 3.1 for a hero shot, and stitch it into one edit — the fastest way to use the open-source LTX-2 AI video generator online.

LTX-2 is the model to pick for volume. Its open weights, speed and low cost make LTX the choice for many ad variants and localized cuts, where per-clip pricing on closed models adds up.
On Vivideo you generate LTX-2 footage online with zero ComfyUI setup and export it watermark-free.

Natively LTX-2 runs in ComfyUI on your own GPUs. On Vivideo you reach the same LTX-2 model — up to 4K with audio — in the browser, with nothing to install or configure.
Batch renders, then finish with captions, voice and a soundtrack in Vivideo's editor.

Vivideo runs both LTX-2 text-to-video and LTX-2 image-to-video. Write a clear prompt or upload a still, and LTX-2 returns fast 4K results built for high-volume production.
Precise prompts scale well with LTX-2; direct the shot, and the LTX-2 AI video generator returns many variants you can refine.

On Vivideo you can use the LTX-2 AI video generator online with zero setup — no ComfyUI, no GPUs. LTX-2 is one of 30+ AI video models on a single subscription. Run LTX-2 text-to-video from a prompt or LTX-2 image-to-video from a still, and switch models per shot.
