LTX Director — Image to Video (ComfyUI)

A Hugging Face Docker Space running ComfyUI with the WhatDreamsCost LTX Director custom nodes and the ComfyUI-LTXVideo extension, for image-to-video generation with LTX-2.3 (distilled fp8).

Usage

1. Wait for the Space to start (first cold boot downloads ~37GB of weights — this takes several minutes).
2. Open the ltx_director_i2v workflow from the ComfyUI workflow menu.
3. Upload a source image, enter a prompt, and run.
4. The generated video appears in the UI and can be downloaded.

Hardware

• GPU: L40S or A100 (48GB). LTX-2.3 requires 32GB+ VRAM and 100GB+ disk. L40S (Ada) is preferred for native fp8 support.

Notes / caveats

• Cold starts are slow. This Space uses no persistent storage, so the LTX-2.3 checkpoint (29GB) and the Gemma text encoder (8GB) are downloaded on every cold boot.
• Public, no auth. Anyone can run jobs on the GPU. Configure the idle-sleep timeout in the Space settings to limit cost.
• The default workflow targets the distilled fp8 checkpoint. The full model and IC-LoRA adapters are available in the node packs but are not preloaded.

Models

• Checkpoint: Lightricks/LTX-2.3-fp8 → ltx-2.3-22b-distilled-fp8.safetensors
• Text encoder: google/gemma-3-12b-it-qat-q4_0-unquantized
