Hey Numeral, first: your Version and your cutting Skills are amazing! Even if I would prefer to get the restored Project 4k77 Version in the Mash Up (to dont have some (for me) stupid new CGI Scenes from the Blu Ray), but the Rest is rly rly incredible.
One thing: VLC Player could not show your own created Sub (btw: thanks for that!) the Player showed these just in a Black Color (which is unreadable). The Blu Ray Player however, has no problems with it and shows them in correct white colour with black shadows. DO you have an idea where the problem is here for the VLC?
I’ve heard a few mentions of this glitch, but have yet to see it on any device I’ve used (And I’ve played my files on a desktop, 2 laptops, A Smart TV, A Chromebook, an Android phone, and others). As best I can figure, it has to do with the subtitle configuration that is the setup in some versions of ffmpeg.
Easiest way to fix it that I know of is to update all of your codecs to the latest version, of say, the K-Lite Codec Pack.

Beyond that, I’m not too sure. The subtitle files are uploaded separately for each project if someone wishes to tweak the font manually if need be, or certain devices allow you to manually customize their appearance (SmartTV software often allows this). These are the best suggestions I can give for the moment.
