Q1: I have had a Roku stick for a while and use Plex all the time to play my stuff. I recently stumbled across some really small size TV and movie files that will help me store a lot more stuff because of the small file size. However, they are H265 files and when I try and play them back through Plex onto the Roku, Plex says it can’t find the video, etc, etc. I have tried forcing Plex to transcode, but it still doesn’t work. Any thoughts?

Q2: Will Roku 3 support these video formats for 4K TVs? 3840 x 2160 UHD with the h265 codec?

After the files are added, click Format > Common Video and set output video format as mp4. The reason mp4 is the target format is that by packing the videos in mp4, the file size will be reasonable small and the video quality remains. HD MP4 video from “HD Video” is suitable.
