HDMV PGS not displaying? The device, video player or media server you're currently using doesn't have native support for PGS subtitles? A good solution is to convert PGS to SRT. In this article, I'll teach you how to convert PGS subtitles to SRT subtitles with an open-source subtitle editor.
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.
Step 1. Download Subtitle Edit from https://www.nikse.dk/subtitleedit. Install and launch it.
Step 2. Click the "File" tab > Import subtitle from Matroska (.mkv) file. (Or drag and drop the video file in other formats into the program).
Step 3. Select the video file with PGS subtitles and click "Open". Subtitle Edit will automatically import and read the video file, and the OCR window pops up.
Step 4. Click "Start OCR" on the OCR window, and Subtitle Edit will start transcribing.
It's inevitable that the transcription is not accurate at times, manually modify the incorrect ones at the box on the left side of the "OCR" button.
If needed, double-click on each transcription to inspect compare matches and modify text associated with each image.
Click "OK" to get back to the main workplace when it's done.
Step 5. Click on the "Format" option above > Select "SubRip (.srt)", set "Encoding" as "Unicode (UTF-8)". Then click the "File" tab > "Save as" > Customize filename for your subtitle > Save
Finally, we have managed to convert PGS subtitles to SRT.
