Creation notes
Prepare video extension inputs
The starting material for this capability is: An existing clip and continuation direction. The intended result is: An extended scene candidate. Check the selected model's exposed input contract before preparation. A visually related source may still be incompatible in media type, size or the role it plays in the request.
Review these concrete details: join continuity, subject drift, new action. Keep the approved brief and original source available. Inspect the complete candidate rather than judging a thumbnail, single frame or short excerpt. Record the exact version you choose and keep rejected alternatives when they explain the decision.

This guide describes a planned capability. The listed models are research candidates; their presence does not make this operation executable in your workspace. Check for a registered action before preparing a paid request.
A proposed Generator recipe still needs saved configuration, compatible stages and reviewed inputs. Inspect the quote and the real output handling before treating a multi-step process as a supported deliverable. Export and native Studio compatibility belong to the chosen artifact, not the name of the capability.
