Parameters for media assets

Last Updated: Jun 25, 2021

Specification

This parameter specifies the output specifications of transcoded audio and videos. Transcoding fees vary with different output specifications. For more information about the billing rules, see Billing of basic services. The following table describes the values of the Specification parameter.

Notice
  • The output resolutions are divided into several open or closed intervals.

  • For more information about the parameter values that indicate different levels of video definition, see the "Definition" section of this topic.

  • The specifications and definition of an output video are determined based on the resolution range where the long side and short side of the video image fall. If the long side or short side exceeds the specified resolution range, the output video has higher specifications and definition.
