We currently have a toolchain that takes an input file (ProRes 4444 .mov) and creates a DVD .iso from it, using ffmpeg, dvdauthor, and mkisofs. It all works fine. We'd like to add subtitles to the DVD images, as we do for our .mp4 outputs, based on an .srt file.
We need this to be something we can run from a script, since the whole output process is automated. Does tooling like this exist?
