A comprehensive production-grade pipeline designed for the LTX-2 model. It specializes in generating high-fidelity video by combining a source image and an audio track to create synchronized content, such as music videos with lip-syncing and dance.<h3 id="key-features-and-architecture">Key Features &amp; Architecture</h3>The workflow is organized into distinct logical stages using subgraphs to manage complexity and optimize hardware resources:<ul><li>Multimodal Input Processing:<ul><li>Image Handling: Uses <code>ImageResizeKJv2</code> to prepare a source image, which acts as the visual foundation for the video.</li><li>Audio Integration: Employs a <code>VHS_LoadAudioUpload</code> node to bring in external audio files, which guide the timing and motion of the generation.</li></ul></li><li>Dual-Stage Sampling Pipeline:<ul><li>Stage 1 (Initial Generation): Focuses on establishing the core motion and structure.</li><li>Stage 2 (Refinement): A secondary pass that refines the video and audio latents for higher quality.</li></ul></li><li>VRAM Optimization:<ul><li>Gemma API Text Encode: Instead of loading the massive Gemma-3 12B model locally, this workflow uses an API-based text encoder. This significantly reduces local VRAM requirements, allowing the workflow to run on GPUs with as little as 12GB to 16GB.</li></ul></li><li>Creative Controls:<ul><li>Camera LoRAs: Includes dedicated slots for LTX-2 Camera Control LoRAs (e.g., Dolly Left), allowing for precise cinematic movement.</li><li>Latent Upscaling: Incorporates a spatial upscaler to enhance the resolution of the final output.</li></ul></li></ul>
