AIDepth: Analyze runs Video Depth Anything Small (Apache-2.0, temporally stable) over the frames and aligns it to MoGe-2 (MIT) metric depth on a few keyframes. Output: depth layer (1/Z like ScanlineRender, or Z), optional depth_metric and N (camera-space normals), upsampled to the plate with a plate-guided filter. Create Camera makes a Camera with the estimated focal length. Model: Auto uses MoGe-2 ViT-B (measured as good as ViT-L and 4x faster); ViT-L is an optional download. Field of view, first that applies: Known FOV (when Field of View is set to known), a Camera on the cam input, the plate's header metadata, then the MoGe-2 estimate. Analyze on 1 to 3 frames keeps the models loaded, so the next frame is fast.

Nuke equivalent

No Nuke class. In a .nk file this node is written as an Oink node that Nuke will not recognise.

AIRoto

AIRoto: click on the plate in the Viewer to add an object (Shift/Alt+click removes, drag draws a box); the mask shows at once.

AINormals

AINormals: Analyze runs MoGe-2 (MIT) per frame: N layer = normals in camera space (X right, Y up, +Z to camera), or world space when a camera is connected to cam.
