H3 Soft Denoise Zone (v2v)
Spatially-varying denoise for H3 v2v: a feathered zone (circle or mask) restyles harder than the rest of the frame, with the strength itself fading across the feather — no matte lines. Differential diffusion, adapted to H3's packed AV latent.

Inputs (11)
| Name | Type | Default | Description |
|---|---|---|---|
| model | MODEL | — | |
| v2v_latent | LATENT | The Guide node's LATENT output with a v2v source active — the SAME latent you feed the sampler. It is the clean footage the protected regions hold on to. | |
| center_x | FLOAT | 0.500–1 | Zone centre, fraction of the frame width. |
| center_y | FLOAT | 0.500–1 | Zone centre, fraction of the frame height. |
| radius | FLOAT | 0.350.05–1.5 | Zone radius as a fraction of the frame's SHORT side (0.5 spans it edge to edge). |
| feather | FLOAT | 0.500–1 | How much of the radius is the soft falloff. 0 = hard edge (matte-line territory), 0.5 = the outer half fades, 1 = fades from the centre out. |
| inner_denoise | FLOAT | 1.000–1 | Fraction of the SAMPLER'S denoise applied inside the zone. 1.0 = the full wired denoise; the sampler stays the master dial. |
| outer_denoise | FLOAT | 0.300–1 | Fraction of the sampler's denoise outside the zone. 0 = the surroundings reproduce the footage untouched. |
| noise_seed | INT | 770–2147483647 | Seed for the re-injection noise field (deterministic; change it only to reroll how protected regions shimmer). |
| mask_feather | FLOAT | 0.100–0.5 | Softens a MASK input (radius as a fraction of the frame's short side): the mask is grown then blurred, so a hard segmentation matte (SAM2 etc.) fades outward instead of leaving a matte line. 0 = use the mask as-is. Ignored for the circle (it has its own feather). |
| maskopt | MASK | Optional: replaces the circle. White areas get inner_denoise, black get outer_denoise, greys blend. A SINGLE mask applies to the whole clip; a mask BATCH (one per frame at 24 fps — e.g. SAM2 video segmentation tracking a person) follows the subject through time, pooled onto the latent grid. Frame counts that don't match the clip are resampled by index. |
