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.
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
resolutionrange 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.

Definition
This parameter specifies the video definition that is used when you call the GetPlayInfo operation, or Use ApsaraVideo Player SDK to play a video. The following table describes the values of the Definition parameter.
The output resolutions are divided into several open or closed intervals.

OD | Original quality | Same as the mezzanine file |
SQ | Standard sound quality | - |
HQ | High sound quality | - |
AUTO | Indicates an adaptive bitrate. Videos of the AUTO definition are generated only if the PackageSetting parameter is set in the transcoding template that you use. For more information, see the "PackageSetting" section of the Basic data types topic. | - |
