Name No String Template name. Length limited to 64 characters. If not passed, it represents no modification.
Comment No String Template description. Length limited to 256 characters. If not passed, no modification is made. If passed empty, the description is cleared.
HeadCandidateSet.N No Array of String Opening candidate list. Fill in the FileId of the video. During transcoding, the opening scene with the aspect ratio closest to that of the main content is automatically selected. If the aspect ratios are identical, the candidate positioned towards the front takes precedence. A maximum of 5 candidate opening scenes is supported. If not passed, no modification is made. An empty array clears the list.
TailCandidateSet.N No Array of String Ending candidate list. Fill in the FileId of the video. During transcoding, the ending with the aspect ratio closest to that of the main content is automatically selected. If the aspect ratios are the same, candidates positioned towards the front take precedence. A maximum of 5 title candidates is supported. If not passed, no modification is made. An empty array clears the list.
FillType No String Filling method. When the video stream configuration width and height parameters are inconsistent with the aspect ratio of the original video, the processing method for transcoding is "padding". Optional filling methods:
  • stretch: stretch each frame to fill the entire screen, possibly causing the transcoded video to be "squashed" or "stretched";
  • gauss: Gaussian blur, maintain video aspect ratio, and apply Gaussian blur to the remaining edge part;
  • white: Leave blank, maintain video aspect ratio, and fill the remaining edges with white;
  • black: Fill with black. Maintain the video aspect ratio and fill the remaining edges with black.

  • The default value is no modification.
