Change a video's aspect ratio without re-generating it (metered; long-running).

One video in, the same shot at a new framing out — the newly exposed edges are painted in rather than cropped to. The input is never modified and the result records it as its lineage parent. No prompt and no model choice: the serving engine is a Moda-side table entry.

Like generate-video, the provider render runs within this call (can take minutes). The response's applied block reports the framing and resolution actually rendered; adjustments lists any snap away from the exact ask. Inputs whose estimate exceeds the per-reframe cost ceiling are rejected before anything is paid for.
