Make video

The quickest way to make a video from a description: no template, node types or graph to wire. Picks a video model that renders the shape and length asked for (Veo 3.1 Lite unless a model is named or it cannot), prepares the render, and answers like estimate_run_cost: the price, whether the balance covers it, and a quoteId. It does NOT start the render: tell the person what it makes and the price, and once they accept, call run_pipeline with the returned pipelineId and quoteId (no inputs; the prompt is saved). Clients that show panels put the price in front of them with a Start render button. Use 9:16 for Shorts, Reels and TikTok. With maxPriceUsd, a video over it is refused with its price rather than shortened. For anything beyond one generated clip (clipping a long video, music, narration, editing a file) use a template, assemble_video or edit_asset instead. Needs the pipelines:write scope; the run needs pipelines:run.
