I'm looking for suggestions for the best way to go about converting the bulk of my media libraries (2000+ movies, 14,000+ TV episodes) into 4Mbps 720p mp4 files with AAC audio. I've found this seems to be the best format for files to be in for direct play compatibility amongst all Plex client apps/devices. I would then use these files to create new separate media libraries that my remote users would only be able to access while I'd still use all the original files for my own local/remote streaming uses. I've considered using the built in Plex Media Optimizer but from what I've seen the it doesn't take full advantage of my hardware. No matter what transcoder settings I configure I never see the CPU usage go above 1000% (barely 60% usage) when running top/htop in Linux. I'd love to be able to make full use of my dual Xeon D-1537 servers which both have full access to my media libraries. I'm wondering what some others may have done to bulk convert their large media libraries. Would love to discuss.
