ComfyUI-LTXVideo 🧩 Workflow Open source

What it is

ComfyUI-LTXVideo is Lightricks' official node pack and workflow collection for its LTX video models, including LTX-2 and the 2.5 series that generate video with synchronised audio. It adds nodes beyond ComfyUI's native LTX support and ships example workflows for text-to-video, image-to-video, IC-LoRA control and an HDR IC-LoRA that upgrades SDR footage to HDR with optional EXR export.

Key features

• Example workflows for LTX-2 and LTX-2.5 generation
• Two-stage pipeline: generate video and audio, then upscale while keeping audio
• IC-LoRA workflows for pose, depth and other control
• HDR IC-LoRA with EXR image-sequence export for grading
• Distilled workflows for faster drafts
• Maintained by the model's developer

How to install

Install through ComfyUI-Manager: open Manager, choose Install Custom Nodes, search for LTXVideo and install; the README recommends the LTX-2 workflows available in the Manager. Model weights download from Hugging Face. The README gives no one-line shell command.

Pricing and rights

The nodes are free, but the repo and LTX-2 weights use the LTX-2 Community License (dated January 2026), not a standard open-source licence; read it before commercial use, as it sets conditions for larger companies.

Who it is for

Video creators and studios who want open-weight video with native audio, or HDR-capable pipelines, inside ComfyUI.

Verdict

The best way to use LTX models in ComfyUI, straight from the developer and updated in step with releases. The custom licence and heavy VRAM needs for full-quality models are the main limits.
