Built on the Lightricks LTX 2.3 22B video diffusion transformer, it delivers high visual coherence, strong scene consistency, and polished motion without manual wiring.The graph supports two creative modes: Image to Video with your first frame as a visual anchor, or Text to Video guided entirely by language. It also includes automatic prompt enhancement, latent upscaling for sharper detail, and optional audio decoding so your final render arrives ready to publish.<h3 id="key-features">✨ Key Features</h3><ul><li>Dual Mode — I2V &amp; T2V: Switch between image-anchored and text-only generation with a single toggle.</li><li>22B Diffusion Transformer: LTX 2.3's massive model delivers temporally consistent motion and refined visual detail.</li><li>Automatic Prompt Enhancement: A built-in helper analyzes your image and text, generating a stronger, time-aware prompt draft.</li><li>Latent Upscaling: Integrated spatial super-resolution doubles sharpness before the final high-resolution sampling pass.</li><li>Audio Decoding: The LTX Audio VAE decodes audio latents and muxes them with your video frames automatically.</li></ul><h3 id="getting-started">🚀 Getting Started</h3><ol><li>Choose your mode: Toggle between Image to Video or Text to Video.</li><li>Set your prompt: Describe the scene action.
