2-step LoRA slashes LTX 2.5 video renders to 2 steps with SoL refiner
TimeTruth2490 · reddit · 2026-11-10
An experimental DMD2-distilled LoRA (checkpoint 6000, rank 64), trained on a single H200, cuts LTX 2.5's stage-1 render from 8 steps to 2 with synchronized audio. The bundled ComfyUI workflow accelerates every stage: the LoRA for rendering, NVIDIA's one-step SoL-Refiner-LTX for refinement, and PrunaAI's pruned VAE decoder. Trained on OpenVid-1M footage at 576x320 and 320x576, outputting 1152x640/640x1152 5-second clips after refinement. Author notes it's an early release good for previews, not production; sample images show photoreal, 35mm-documentary, and 3D-animation styles in both T2V and I2V.
