Are you looking to convert to "true 4K" video or "4K UHD" video, which is totally different. Every consumer device on the market today labeled 4K actually means "4K UHD", or 3840x2160 resolution, but everything is marketed as being 4K, but it's not true 4K. If you're trying to convert anything to run on a consumer based TV/UHD player/video file to run through an Nvidia Android TV or a new Chromecast or Roku, it's actually referring to a 3840x2160 file, not a 4096x2160 file. There's a big difference between the two, so I was just making sure you were referring to the correct format.
