Converting .mp4 videos to .trp format.
Converting MPEG-4 Videos directly to HD Video Transport Streams (.mp4 to .trp conversion) is certainly possible and should be quite straightforward, even though it is not a very common conversion.
Use one of several available video editing programs or (online) conversion tools, such as SUPER or Wondershare Video Converter, which allow users to import MP4 videos and export them in TRP format.
