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.
