Minimax_H3-LatentUpscaler_Adv
Upscales MiniMax H3 latents (16x compression). conditioning_mode: pass_through / update_meta / full_sync. update_meta fixes fl2va shape mismatch without re-running TE.

Inputs (9)
| Name | Type | Default | Description |
|---|---|---|---|
| samples | LATENT | — | |
| upscale_method | COMBO | 5 options: nearest-exact, bilinear, area, bicubic, bislerp | |
| width | INT | 5120–16384 | — |
| height | INT | 5120–16384 | — |
| crop | COMBO | 2 options: disabled, center | |
| chunk_size | INT | 80–128 | Frames per chunk for low-VRAM GPUs (e.g. RTX 3060 8GB). 0 = process all frames at once (faster but uses more VRAM). |
| safe_precision | COMBO | enable | Cast to FP32 during interpolation to prevent NaN artifacts on FP16/BF16. |
| conditioning_mode | COMBO | pass_through | pass_through = do not touch conditioning (standard H3). update_meta = update latent_h/w and REMOVE refs/keyframes (fixes fl2va shape mismatch + avoids ghosting, zero TE cost). full_sync = update latent_h/w AND upscale refs/keyframes (keeps visual references, may cause ghosting). |
