Here's an English sub for Saenai Heroine No Sodatekata Fine shared /r/Saekano users.
The video is 1080p that is less than 1GB due to the low video bit rate, I'm not really familiar with anime encoding in general. It also features lyrics for the songs in the movie. As for the quality of the subs, it might look like a mess since it's been translated back and forth between friends in their free time for a whole week.
