# LMS / Sharpness LoRA [`minimax_h3_lms_v1.0_r64.safetensors`](../loras/minimax_h3_lms_v1.0_r64.safetensors) is a rank-64 LoRA for sharpening a source video while keeping a natural, photorealistic appearance. It is intended mainly as a second pass over an existing clip. ## Workflow [`workflows/minimax_h3_lms_workflow.json`](../workflows/minimax_h3_lms_workflow.json) Put the source video into `MiniMaxH3AddGuide`, connect the video VAE, use `frame_idx = 0`, and match the output resolution and frame count to the source. Start with LoRA strength `1.0`. Use this caption: ```text Enhance this video with sharp, crisp details while preserving a natural photorealistic appearance. ``` The aligned guide is not an ordinary reference video. Its latent frames occupy the same temporal and spatial positions as the output, helping preserve motion, timing, framing and sync. The model was trained primarily for `ref2va` with guide latents alone. Combining Add Guide with additional native references is experimental and may not improve the result. ## Examples
