<\/p>\nPreviously, creating videos using neural networks was the prerogative of cloud services like Runway or Luma. Today, if you have a modern Nvidia graphics card, you can generate high-quality videos right on your computer. In this post, I will tell you how to set up local video generation using ComfyUI<\/b> and the effective LTX-2.3<\/b> model.<\/p>\n
<\/p>\n
For work we will need:
\n– ComfyUI:<\/b> a powerful interface with a node-based architecture that allows you to flexibly customize the generation process.
\n– LTX-2.3:<\/b> A modern model from Lightricks, optimized for creating smooth and detailed videos with relatively moderate video memory requirements.<\/p>\nHardware requirements<\/h2>\n
Generating video is a much more resource-intensive process than working with images:
\n– Video card (GPU):<\/b> Nvidia RTX with 8 GB VRAM is the minimum required for a resolution of 768×512. For comfortable operation and higher resolutions, it is highly desirable to have 16\u201324 GB of VRAM.
\n– Random access memory (RAM):<\/b> minimum 32 GB. Video models and VAEs take up a lot of space when downloading.
\n– Disk space:<\/b> about 500 GB for the model itself and related components.<\/p>\nSetup and launch<\/h2>\n
The process of launching LTX-2.3 in ComfyUI is as follows:
\n1. Update ComfyUI:<\/b> The model is relatively new, so make sure you have the latest version of the interface installed.
\n2. Install Workflow:<\/b> The easiest way is to find a ready-made JSON template for LTX Video. The model requires specific nodes to work with video latent space.
\n3. Prompt and parameters:<\/b> Enter a description of the scene in English. Note that the LTX-2.3 understands motion well (eg “camera orbits around”, “fast movement”).<\/p>\nWhy choose LTX-2.3?<\/h2>\n
LTX-2.3 is notable because it delivers results comparable to proprietary cloud services, but runs locally. This gives you:
\n– Complete privacy:<\/b> your prompts and generated videos do not go to other people\u2019s servers.
\n– Control:<\/b> you can experiment with frame rate (FPS), resolution and prompt strength without having to pay for each attempt.<\/p>\n
Local video generation is still in active development, and LTX-2.3 is a great entry into the world of \u201chome Hollywood.\u201d<\/p>\n
