[Andy Winter]"what are your experiences? or don't you master in resolve..."
Conceivable to overlay a "Black Movie with subtitles" exported from something like MacCaption, which is what I would normally do and advise it I wanted to master out of Resolve.
The thing with subtitles, though, is that there are so many variables -- language, X-Y formatting, (centre/ lower third/ upper, etc.) that no one single file is going to satisfy all requirements. You will want to keep it editable because somebody is going to want to change the font, or the edge boldness, or something.
I like being able to embed stl files in DVDs and BluRays -- NOT burn in the titles if I can help it. Nice feature of Encore, to be able to open a subtitle cell and fix it.

I have talked about it to Peter some time ago and i think so have others.
I see no reason why Resolve could not have "metadata" subtitles option.
Making subs in other package and importing as "video" works but is so limiting.
Specially killing this Resolve's multi resolution workflow idea when you have
to have many video files for different resolutions.
Seems time consuming and cumbersome.
In feature work i have seen this many many many times and it just takes Resolve out of the
final mastering workflow instantly. Maybe better integration with Fusion in the future would help it.
