I tried h.265 a few times, and ran into an apparent common problem of color being wrong. People's faces appear burnt orange. Looks this way on both my pc/vlc and emby direct play to my roku ultra. I googled it, and many others have this problem. After a number of tests, I gave up. Sure, h.265 will produce a file roughly 2/3's the size as h.264, and that would be nice, but the color problems, and the encode time jumping from an hour to a day is too much. Sure I can adjust the quality level to shorten the time, but even with long time the color problem was still there, so I eventually gave up on h.265.
