Comment No String Template description information. The length cannot exceed 256 characters.
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.

During transcoding, the ending with the aspect ratio closest to the main content is automatically selected.

  • stretch: stretches 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.

  • Default value: stretch.
