  # @!attribute [rw] width_pixels
  #   @return [::Integer]
  #     The width of the video in pixels. Must be an even integer.
  #     When not specified, the width is adjusted to match the specified height
  #     and input aspect ratio. If both are omitted, the input width is used.
  #
  #     For portrait videos that contain horizontal ASR and rotation metadata,
  #     provide the width, in pixels, per the horizontal ASR. The API calculates
  #     the height per the horizontal ASR. The API detects any rotation metadata
  #     and swaps the requested height and width for the output.
  # @!attribute [rw] height_pixels
  #   @return [::Integer]

  #     The width of the video in pixels. Must be an even integer.
  #     When not specified, the width is adjusted to match the specified height
  #     and input aspect ratio. If both are omitted, the input width is used.
  #
  #     For portrait videos that contain horizontal ASR and rotation metadata,
  #     provide the width, in pixels, per the horizontal ASR. The API calculates

  #   @return [::Integer]
  #     The height of the video in pixels. Must be an even integer.
