NEW VIDEO MODEL: LTXV day-1 Native Support in ComfyUI
Blog post from Comfy
LTX Video (LTXV), a cutting-edge video generation model developed by Lightricks, is now natively supported in ComfyUI, allowing users to generate high-quality videos in real-time. This model, based on a 2-billion-parameter DiT architecture, can produce 24 FPS videos at a 768x512 resolution faster than they can be watched, specifically in just four seconds for a five-second video. LTXV is optimized for accessible GPUs, such as the RTX 4090, and uses bfloat16 precision to ensure efficient memory usage without compromising quality. The model's Diffusion Transformer architecture guarantees smooth motion and avoids common problems like object morphing, making it ideal for creators aiming to produce consistent long-form videos. LTXV's native integration into ComfyUI includes custom nodes branded as "LTXVideo," which are easily accessible through the ComfyUI Manager, offering additional functionalities such as image-to-video conversion. The introduction of LTXV in ComfyUI opens new avenues for creators to explore real-time video generation and storytelling possibilities.
