This is just a curiosity motivated question, nothing else. The world of DTS is a mystery to me. Both DTS:X and DTS-HD are excellent codecs as far as I can tell from the many Blu-rays I have in DTS-HD, and the few 4K ones I have that are in DTS:X (so few that I can only remember two, Gladiator and the X-Men Phoenix movie), but I could never find any information on how to export a mix to either of them. Many years ago Adobe Premiere had some sort of expensive plugin that could export to some type of DTS, that I never bought and eventually was discontinued. Other than that, I never saw any program that can encode audio and has a DTS encoder, even the basic one from the 2000’s.
Is there anyone here who encodes to either variant, and how much did you pay for it? Is it a permanent license or a subscription?
