MiniMax H3 LMS Upscale Guide (Experimental)
Experimental LMS refinement AFTER an image/video upscaler. Encodes one enlarged RAW scene as a native guide and creates a fresh AV target at the same size. Does not reconstruct Ref2VA caches, send images to Qwen, or change timing. Requires full-scene sampling memory; this is not a tiled CAT replacement with the same memory footprint. Separate the sampled video latent for decode/save; discard sampled audio. Upscale Segment Save retains the original checkpoint sound.

Inputs (6)
| Name | Type | Default | Description |
|---|---|---|---|
| state | H3_CHAIN_UPSCALE_STATE | Current scene from a pixel Upscale Adapter. Its RAW frame clock must match the guide exactly. | |
| clip | CLIP | H3 Qwen text encoder. Only the enhancement caption is encoded; no visual refs/cache are used. | |
| video_vae | VAE | H3 video VAE for encoding the enlarged guide. | |
| prompt | STRING | Enhance this video with sharp, crisp details while preserving a natural photorealistic appearance. | — |
| imagesopt | IMAGE | One complete enlarged RAW scene from DLSS5 or another frame-preserving upscaler. Connect images OR video, not both. No trim or resampling. | |
| videoopt | VIDEO | Alternative RAW 24 fps guide from a VIDEO upscaler. Decoded as ONE FULL SCENE in RAM, not streamed. Its audio is ignored. |
Outputs (6)
| Name | Type | Description |
|---|---|---|
| positive | CONDITIONING | Caption plus a full-length native H3 video guide at frame zero. |
| latent | LATENT | Fresh empty joint AV target. Use RandomNoise, denoise=1 and LMS + Ref2VA Turbo on the model; do not use Pass-2 AV Prepare. |
| width | INT | Actual guide width. |
| height | INT | Actual guide height. |
| raw_frames | INT | Unchanged RAW frame count. |
| status | STRING | Guide route, memory warning and audio preservation contract. |
