      VOD supports initiating video processing by replacing complicated parameter sets with parameter templates. It offers a variety of preset parameter templates suitable for different video processing scenarios.

      Video Conversion

      Preset parameter templates for video conversion are divided into the following types:

      • Preset transcoding templates
      • Preset remuxing templates
      • Preset animated image generating templates
      • Preset time point screencapturing templates
      • Preset sampled screencapturing templates
      • Preset image sprite generating templates
      • Preset adaptive bitrate streaming templates
