# Stereoplate

> A browser instrument that turns a still + depth map into an SBS stereo keyframe.

Stereoplate is a Stewardship packet. See a mind, be polite.

## What this is

Client-side Depth Image Based Rendering (DIBR). You bring a color still and a depth map (Depth Anything, NanoBanana, or any grayscale plate). Stereoplate warps a mesh with six parallax planes, then previews and exports side-by-side stereo for video models such as MiniMax H3 and Luma.

It does not estimate depth. It does not generate video. It does not run a Looking Glass light field. It does not require an account inside the plate.

## How to use

1. Drop still + depth. White is near by default (Depth Anything / NanoBanana).
2. Tune Strength and Screen plane until the subject sits on the glass.
3. Edge snap (joint bilateral) pulls soft depth onto the still's silhouette. Useful on hair, cables, visors. A no-op on hard maps.
4. Edge plump grows the foreground over remaining tears. Fill gaps stretches occlusions. Overscan zooms out border pull.
5. Gap matte Green + fill off marks holes as #00FF00 for Imagine / NanoBanana inpaint. Prefer inpainting each eye separately with the original still as reference.
6. Export H3 1080p half SBS (1920×1080, eyes squeezed into 16:9) unless the model wants full 32:9.

Views: SBS, anaglyph (Dubois), wiggle, still, depth. Keys 1–5.

## Limits (do not over-claim)

- A single view cannot invent what the camera never saw.
- Depth Anything halos cause tears; snap + plump reduce them; they do not vanish.
- Imagine may hallucinate stereo-inconsistent fills. Check wiggle.
- Half SBS = 16:9 squeezed pair. Full SBS = 2:1 / 32:9 true pair.
