Highlights of LTXV in ComfyUI

1. Real-time Generation Speed

LTXV can produce 5 seconds of 24 FPS videos (768x512) in only 4 seconds, faster than they can be watched.

LTXV is designed to maintain precision and visual quality without compromising speed or memory efficiency. It is optimized for widely available GPUs like the RTX 4090 and leverages bfloat16 precision for efficient memory use without sacrificing quality.

2. High Video Quality

LTXV delivers unmatched speed, producing a five-second video (121 frames at 768x512 resolution) in just four seconds using 20 diffusion steps. Its Diffusion Transformer architecture ensures smooth motion and eliminates common issues like object morphing, providing superior motion consistency. Additionally, the model is highly scalable, and capable of generating long-form videos with consistent quality, empowering creators to push the boundaries of storytelling.

3. Native Support in ComfyUI

LTXV is now natively supported in the latest ComfyUI. Lightricks has also developed custom nodes, branded as "LTXVideo", specifically for ComfyUI. These nodes are available right within the ComfyUI Manager. Just search for “LTXVideo”!
