Upload one video part, at most 8 MiB decoded. Use the exact add_path and upload_id returned by init_media_upload. Preview never sends bytes.

> **Warning** This tool changes the account. It is absent from the tool list on the Free plan, and it previews by default: without `confirm: true` it describes the change and applies nothing.
