AIVectorGenerator (Nuke SmartVector): Generate runs optical flow (SEA-RAFT, BSD-3) in the AI worker and caches vectors per frame. Adds layers motion (forward u,v + backward u,v in pixels, v up), forward, backward and occlusion; SmartVector layers add frame distances 2-16 for VectorDistort. Model Auto picks the best flow model that fits the free GPU memory. Resolution auto runs the flow at about 1024 px on the long side. Viewing a generated frame never blocks the app: the vectors of the last frames you looked at stay in memory.

Nuke equivalent

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

AIKeyer

AIKeyer: green/blue screen colour-difference keyer (screen colour auto or picked, balance, clip black/white) with float-correct despill (none, limit, or IBK-style subtract).

GenFill

Generative fill: replace the masked region from a text prompt.
