PGS Subtitle Won't Appear Fix – How to Convert PGS to SRT

Q: I have searched for a way to convert PGS subtitles associated with some MKV files to SRT that Roku can recognize. Does anyone know what settings I can try to use?

A: Actually, PGS is not a text-based subtitle file type, it's just a timed sequence of graphic images. Just like when you extract subtitles from DVD, converting PGS to SRT, OCR (Optical Character Recognition) is a necessary process. Simply put, you need a third-party tool to identify the subtitles on the image and then transcribe it to text-based SRT subtitle files.

Now, to save your trouble scouring for a proper subtitle capture app, here's a well-tested one – Subtitle Edit. Subtitle Edit is completely free and an open-source PGS to SRT converter that features powerful OCR, wide range support of subtitle formats (200+) and sleek operation buttons. By the way, if you are acquainted with Handbrake, you can easily get the hang of Subtitle Edit since they are such alike.
