As you can see, subtitles work the same way in two video players.
Different image aspect ratio gives subtitles a different scale and spacing, but colored words overlay white words without shifting.So, we have the problem: These subtitles do not work correctly in Emby Theater.
The solutions:
1. Use a different video player for such videos.
2. Change subtitles or renderer settings in the Emby Theater application.
3. Send a bug report to Emby Theater developers if the subtitles still do not work properly.
from what i've seen from your screen shoot, your light fill is on the top and bottom, not the side (left and right) since the effect is not horizontal, i do think it wont have problem, so it's fine that way
BUT if you use it on ultra wide, like mine for example, 3440x1440 the problem will appear
any 1080p video you play would have black border in left and right, and it will stretch the subs when in full screen (will make spacing issue but it's fine atleast for the opening section)
on another note, kindly try the subs in minute 20+ that's the main problem
i've just checked the early minute / opening is fine without issue (only spacing issue which is minor to me)
the problem appears there
