Skewing an image stretches the pixels that already exist; changing the viewpoint means working out what the subject looks like from somewhere else and drawing the parts the first frame never recorded. That is a genuinely different operation, and it is why a warp always looks like a warp. The re-shoot runs on the Nano Banana image model in the browser with free credits to start.
Drop in the original frame, choose the format, and the credit estimate updates before you commit; a failed run is refunded automatically.
