Please accept my apologies - I am new to all of the below - before 2 weeks ago I knew what MKV and MP4 were but that was it... and I had never used Plex. I am here to learn :)
I'm running Plex Server 0.9.16.3.1840 on my DS1515+ (DSM 6.0-7321)
Because my NAS is just too slow to transcode my Blu Ray rips (I use Make MKV), I've decided to re-encode them to be Direct Play-ed to my Google Chromecast or PS4.
I've found that picking the "Original Quality" preset works a treat. The resultant quality is perfect, and it Direct Plays to both devices with the tests I've done. As a sidenote, since I have no need for the original (and larger file size) MKV files after the conversion is done, currently I am moving the converted MP4 files elsewhere - deleting the original MKV files and re-synchronising the MP4 files back into my Library as if they are the new Originals.
Now, time for my questions.
1) How are subtitles chosen when using this Optimize process? I seemingly have no option to select which subtitle to use.
2) Is there a way I can force the Optimizer to always use Forced English subtitles when doing this "Pre-Transcoding"?
3) Is there a way I can tell the difference between the Forced English-only subtitles, and the regular English subtitles when using the Web App or my iOS app? They are all just called "English (PGS)".
I am really not interested in using something like Handbrake to re-encode manually every file I rip. I really love the "set and forget" nature of the Optimize feature... it's just messing up some movies by automatically picking the first subtitle track it can find.
I think I've ripped and Optimized "The Bourne Ultimatum" about 4 times now and have yet to get it right.
Thanks in advance!
