Hello. I am working with one friend in a Fan-Edit of the three prequel movies. We are from Spain and we will make them both in English and English with spanish subtittles. We have a problem with the spanish subtittles. We hardcode them to the movie using ffmepg, the command-line sofware we use for that, but it does not support SUP/pgs subtittles. This means we need to convert them to SRT. I tried to convert the PGS/SUP subtittles i obtained from the official Blu-Rays of the prequels to SRT using SubittleEdit program, and online using https://subtitletools.com/, but the result is not good, with a lot of errors like two words joined, or wrong letters. Do you guys know how can i convert the Blu Ray subtittles to SRT without any error?
