I totally agree with the hvec x265. Option. I started using x265 on a lot of my files late last year. It is outstanding with what you can do with it. If you are going to build a big library it is a huge benefit when wanting to save space.
I do think this transcoding format should be added as an option. This format is getting more widely used everyday. Most of my users use the newer Fire Sticks and Roku boxes, all compatible with hvec. Someone mentioned avi users, unfortunately avi is going to get pushed out. Plex is suppose to be for the future. We don’t want to get behind. the curve.
