  title: Mux Create Asset From URL
  summary: Ingest a video from a hosted URL, poll the new asset until ready, and confirm the input details Mux processed.
  description: >-
    Creates a Mux Video asset directly from a publicly reachable source URL,
    polls the asset until its status reaches ready, and then reads the asset's
    input info so you can confirm the resolution, frame rate, and container Mux
    actually ingested. Every step spells out its request inline so the flow can
    be read and executed without opening the underlying OpenAPI description.
