Is there some way to get the Spanish subtitles of this and/or your other PT edits? Or at least the English subtitles in an independent file so I can translate it myself.
I suggest you PM MalàStrana, who created the subtitles. I am currently working on a final version of these three edits, and he is planning to do subtitles for those as well. I can’t speak for his workflow for this, but it may be that he could provide you with finished (synced) English subtitles and you could translate these to Spanish. That would be a welcome addition to this final version, if you are willing.
So far I have sent him a screener for Episode III so he can sync the subtitles, with Episodes I and II coming after.
