Thank you for your answer.
“Do you want to slap an external drive/stick into the TV’s USB port?”
Yes. The question is what format gives the best quality? DVD was good for Standard Definition. BluRay was for HD. What is best to encode 4K with in Media Encoder and then maybe Encore for something to put on an external drive/stick? Not YouTube quality, mind you. Again, like BluRay disc was best for HD, what is best for 4K (except those new 100Gb BD discs of course).
Thanks again.
