About LTX-2 on Vivideo

LTX-2 is Lightricks' open-weights video generation model — up to 4K with audio, released under the LTX-2 Community License. As an AI video generator, LTX is prized for speed, low cost and transparency, which is why developers run it in ComfyUI pipelines.

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.

Because LTX-2 is open-source and inexpensive (from about $0.04 per second natively), it's the model for volume. On Vivideo you get watermark-free LTX-2 output without managing weights or infrastructure.

LTX-2 rewards clear prompts and scales well. A precise LTX-2 video prompt returns fast 4K results, so you can produce many ad variants or localized cuts without a per-clip premium.

LTX-2 has trade-offs: raw realism can trail closed models on hero shots. For a flagship scene, Vivideo lets you switch to Sora 2 or Veo 3.1, then use LTX-2 for the high-volume rest — all in one edit up to 10 minutes.

Is LTX-2 free? You can try the LTX-2 AI video generator free on Vivideo with daily generations, no credit card and no ComfyUI. Upgrade cheaply for watermark-free video.

Genuinely impressed

I've tried a bunch of AI video tools and Vivideo is the first that actually nailed what I described. A one-line prompt turned into a polished clip in minutes, and the avatars and voices feel real.
