HeadCandidateSet.N No Array of String Opening candidate list. Fill in the FileId of the video. During transcoding, the opening closest to the aspect ratio 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 title candidates is supported. Not passing this parameter means no modification, while passing an empty array means clearing.
TailCandidateSet.N No Array of String Ending candidate list. Fill in the FileId of the video.

Passing an empty array means clearing.
FillType No String Filling method. When the aspect ratio of the video stream configuration width and height parameters is inconsistent with that of the original video, the processing method for transcoding is "padding". Optional filling methods:
  • stretch: Stretch each frame to fill the entire screen, which may cause the transcoded video to be "squashed" or "stretched";
  • gauss: Gaussian blur, maintain video aspect ratio, and use Gaussian blur for 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.
