Lightricks/LTX-Desktop

An open-source desktop app for generating videos with LTX models

What it solves

LTX Desktop provides a user-friendly desktop interface for generating and editing videos using LTX models. It removes the technical barrier of running complex AI video generation models locally or via API, offering a unified workspace for creators who want to turn text, images, or audio into video.

How it works

The application uses a three-layer architecture consisting of a React-based frontend, an Electron wrapper for OS integration, and a Python FastAPI backend. Depending on the user's hardware, it operates in two modes:

  • Local Mode: On Windows and Linux machines with NVIDIA GPUs (16GB+ VRAM), the app downloads model weights and runs generation directly on the GPU.
  • API Mode: For macOS and unsupported hardware, the app connects to the LTX API to handle the heavy lifting of video generation.

Who it’s for

Content creators, AI artists, and developers who want a dedicated desktop environment for AI video generation and editing without needing to manage command-line interfaces.

Highlights

  • Multi-modal generation: Supports text-to-video, image-to-video, and audio-to-video workflows.
  • Video Editor Interface: Includes a built-in editor and project management for refining generated clips.
  • Video Edit Generation (Retake): Allows for iterative editing of existing videos.
  • Flexible Deployment: Supports fully local execution on high-end NVIDIA GPUs or cloud-based generation via API.
