LTX-Video by Lightricks
LTX-Video, developed by Lightricks, is an advanced AI-driven tool for generating and editing videos. It offers motion consistency, keyframe control, video extension, high resolution, and auto-prompt understanding. It integrates with LTX-Studio web app and ComfyUI and provides both open-source and commercially licensed checkpoints for flexibility.
Overview
LTX-Video is an AI-powered text-to-video and video editing tool built by Lightricks, a well-known company behind popular apps like Facetune and Videoleap. It specializes in enhanced motion consistency, controllability with keyframes, forward/backward video extension, and higher-resolution output.
A major feature update introduces keyframe support, allowing users to define specific frames for greater control over animation and transitions. Video extension helps in maintaining fluidity by extending content seamlessly. The auto-prompt understanding feature ensures that the AI better interprets user input, making video generation more intuitive.
LTX-Video is now available in LTX-Studio, a web-based platform, as well as natively in ComfyUI.
The tool is open-source but comes with different licenses for various checkpoints, meaning some models allow commercial use while others do not.

Users are impressed by Lightricks’ ability to generate high-quality results quickly, with reports of five-second videos created in just two seconds on powerful hardware like the H100. The model relies on a high compression rate through VAE, making it scalable without compromising quality.
Community members are testing it on various GPUs, with some achieving solid results even on lower-end hardware. While the model runs well on Nvidia cards, Mac users report mixed experiences. Some praise its efficiency, while others struggle with noise issues.
Overall, Lightricks’ model is seen as a strong contender in the AI video space, though some remain skeptical of marketing claims versus real-world performance.

Since Lightricks has introduced new AI video features, focusing on extending videos and keyframe-based interpolation, users can now condition video generation on specific images or short video segments, controlling motion and frame transitions. The update is already supported in ComfyUI, but results so far are mixed, with some users reporting impressive speed but inconsistent quality.
Some testers praise the model’s efficiency, while others find results glitchy, especially for complex human motion. A few users note that shorter, simpler prompts yield better outputs. Keyframe-based interpolation excites many, but skepticism remains over whether it can truly maintain character and scene consistency.
With alternatives like Wan2.1 and the upcoming HunYuan model, comparisons are inevitable. LTX is fast and lightweight, but many say it struggles with quality compared to competitors. Some users are working on fine-tuning and workflow optimizations, hoping to improve stability. Despite mixed reviews, the addition of keyframe conditioning is seen as a step toward more flexible AI-generated video.

The buzz around LTXVideo 0.9.6 Distilled is huge. Folks are freaking out over how fast it runs and how solid the results look. Lots of users say they’re getting good video frames in just seconds even using mid-tier GPUs like the RTX 3060. The model only needs 8 diffusion steps so it cranks out usable stuff super quick without burning tons of compute time like the older ones.
People like using the official ComfyUI setup especially when they throw in a prompt helper node like ChatGPT. That combo seems to give better output. Sure some still feel a bit lost opening Comfy for the first time but being able to just grab and remix shared workflows makes it way easier to jump in. The 0.9.6 update also added new stuff like a smarter guidance node and some kind of random inference trick that helps with quality.
There's a lot of curiosity around the full-size version of the model too. It’s the same size file but might look even better if your GPU has the room to handle it. A few people mentioned that while the speed’s awesome you might still get some weird visuals in spots so it’s not flawless.
All in all this version feels like a solid jump forward and might become the go-to for quick high-quality video runs.

A platinum-haired woman with flawless, porcelain skin slowly rises in shimmering water under a starlit sky. Soft ripples distort her reflection while faint cosmic lights flicker around her curls. She blinks slowly, her gaze piercing yet serene, as tiny stardust particles drift across the surface. The water glows faintly beneath her, echoing the constellations above in a dreamlike mirror. Her expression shifts ever so slightly — poised, enigmatic, ethereal. Compare ToolsGenerated on April 21, 2025:
A golden valley of surreal beauty stretches beneath the clouds—burnt-orange trees with dense, feathery foliage stand scattered across mirror-like pools that reflect jagged blue-grey mountains and cotton clouds. The drone camera glides low and smooth above the shimmering water, weaving between the trees, their reflections rippling softly as the breeze brushes the grass. Light flares off the surface as the view slowly elevates, revealing the full majesty of the glowing valley and distant peaks. Compare ToolsGenerated on April 21, 2025:
