How to Use LTX Desktop
Check System Requirements: Ensure your system meets the minimum requirements: Windows 10/11 (64-bit), NVIDIA GPU with 32GB+ VRAM (RTX 5090 recommended), 32GB RAM, and 160GB free disk space. For macOS users: Apple Silicon (M1 or later), macOS 13+, 16GB+ unified memory.
Download and Install: Download the installer from GitHub releases page - .exe for Windows or .dmg for macOS. Run the installer and follow the installation wizard. For macOS users, drag the app to Applications folder.
First Launch Setup: Launch the app and accept the LTX-2 Community License Agreement. The app will begin downloading required components: Python environment (~10GB) and AI models (~150GB) for Windows users. MacOS users will need to enter an LTX API key as local generation isn't supported.
Download Required Models: Use the download wizard to select needed models: LTX-2.3 main weights (~20GB required), distilled_lora for fast mode (~500MB), upsampler for 1080p output (~2GB), text encoder (~5GB optional), Z-image Turbo for image generation (~30GB optional).
Configure Optional API Keys: Optionally set up Gemini API key for context-aware gap fill feature and fal.ai API key if you can't run Z-Image Turbo locally. These are not required for basic functionality.
Generate Videos: Use the Gen Space for AI generation features like text-to-video, image-to-video, audio-to-video, and retake functionality. Start with 720p output initially, use upscaler for 1080p if needed.
Edit Videos: Use the non-linear editor features including trim tools, transitions, color correction, text overlays, and subtitle editing. Import/export XML timelines for compatibility with other NLEs.
Export Final Video: Export your finished video in H.264 or ProRes format. If you downloaded the upscaler model, you can output at 1080p resolution.
