The height of the output video. Unit: pixels.

The value must comply with the following rules:

• Height ≥ 100: The height of the video is greater than or equal to 100 pixels.
• max(Height,Width) ≤ 2560: The width or height of the video, whichever is greater, cannot exceed 2,560 pixels.

• min(Height,Width) ≤ 1440: The width or height of the video, whichever is smaller, cannot exceed 1,440 pixels.

  Note The resolution of a video that is transcoded by using H.265 Narrowband HD™ transcoding cannot exceed 1280 × 720 pixels.

The width of the output video. Unit: pixels.

The value must comply with the following rules:

• Width ≥ 100: The width of the video is greater than or equal to 100 pixels.
• max(Height,Width) ≤ 2560: The width or height of the video, whichever is greater, cannot exceed 2,560 pixels.
• min(Height,Width) ≤ 1440: The width or height of the video, whichever is smaller, cannot exceed 1,440 pixels.

The frame rate of the output video. Unit: frames per second (FPS). Valid values: 1 to 60.

The bitrate of the output video. Unit: Kbit/s. Valid values: 1 to 6000.

The bitrate of the output audio. Unit: Kbit/s. Valid values: 1 to 1000.

The group of pictures (GOP) size of the video. Unit: frames or seconds. When the unit is frames, the value format is {Number}. When the unit is seconds, the value format is {Number}s.

• Valid values when the unit is frames: 1 to 3000.
• Valid values when the unit is seconds: 1s to 20s.

The video encoding profile. The profile determines how a video is encoded. In most cases, a greater value indicates better image quality and higher resource consumption. Valid values:

• 1: baseline. This value is suitable for mobile devices.
• 2: main. This value is suitable for standard-definition devices.
• 3: high. This value is suitable for high-definition devices.

The audio encoding profile. Valid values:

• aac_low
• aac_he
• aac_he_v2
• aac_ld

The audio codec. Valid values:

• aac
• mp3

The audio sampling rate. Valid values: 22050, 32000, 44100, 48000, and 96000. Unit: Hz.

The number of sound channels. Valid values:

• 1: mono
• 2: binaural

Specifies whether to enable triggered transcoding. Valid values:

• yes: enables triggered transcoding.
• no: disables triggered transcoding.

The encryption settings. The value must be a JSON string that includes the following fields:

• EncryptType: the type of encryption. Set the value to aliyun.
• KmsKeyID: the ID of the customer master key (CMK) in Key Management Service (KMS).
• KmsKeyExpireInterval: the rotation period of the CMK. Valid values: 60 to 3600. Unit: seconds.

The source-based resolution settings. This parameter takes precedence over other resolution settings. The following fields must be included:

• Type: You can set this field to short, long, or screen. short specifies that the resolution of the output video is adapted to the shorter side, long specifies that the resolution of the output video is adapted to the longer side, and screen specifies that the output video has an adaptive resolution.
• Value:
  Note

  • Set this field to 360, 480, 540, 720, or 1080 if the Type field is set to short.
  • Set this field to 640, 848, 960, 1280, or 1920 if the Type field is set to long.
  • Set this field to 640*360, 848*480, 960*540, 1280*720, or 1920*1080 if the Type field is set to screen.

The source-based frame rate settings. This parameter takes precedence over other frame rate settings. The following fields must be included:

• UpLimit: the maximum frame rate. Set this field to an integer from 1 to 60. The value must be greater than the minimum frame rate.
• LowerLimit: the minimum frame rate. Set this field to an integer from 1 to 60. The value must be smaller than the maximum frame rate.

The source-based bitrate settings. This parameter takes precedence over other bitrate settings. The following fields must be included:

• UpLimit: the maximum bitrate. Set this field to an integer from 128 to 10000. The value must be greater than the minimum bitrate.
• LowerLimit: the minimum bitrate. Set this field to an integer from 128 to 10000. The value must be smaller than the maximum bitrate.
• Factor: the ratio of the output bitrate to the source bitrate. Valid values: 0.1 to 1. The value is accurate to one decimal place. A value of 1 indicates that the output video has the same bitrate as the source video.

Other source-based settings. The following fields are included:

• KeyFrameOpen: Valid values: yes and no.
• Copyts: Valid values: yes and no.
• SeiMode: Valid values: 0, 1, and 2. 0 specifies that no supplemental enhancement information (SEI) messages are passed through, 1 specifies that part of SEI messages are passed through, and 2 specifies that all SEI messages are passed through.
