Extract .srt subtitles from Blu-ray Disc/BDMV/BD ISO

There are many guides for Blu-ray subtitles processing, like extracting PGS subtitles from a Blu-ray BDMV structure, converting Blu-ray .sup subtitles to .srt, ripping subtitles from a Blu-ray movie, but none tells you how to extract .srt subtitles straightly from a Blu-ray Disc. That’s easy to understand- you can’t expect a free subtitles converter app (e.g. Suprip, BDSup2Sub, HD-DVD/Blu-ray Stream Extractor) comes with Blu-ray hacking features. Only Blu-ray rippers can handle Blu-ray AACS and BD+ copy protections. But even best ranking Blu-ray rippers can be very week in the processing of Blu-ray subtitles- MakeMKV rips Blu-ray to MKV without changing the PGS subtitles at all. Pavtube Blu-ray Ripper burns only one subtitles stream to the movie when converting BD to AVI, MP4, MKV, etc. The app I’m going to introduce in the following passages, however, does rips .srt subtitles from Blu-ray Disc, Blu-ray folder (BDMV), and Blu-ray image file (BD ISO). Don’t be surprised- this is a Blu-ray ripper more than a Blu-ray subtitles converter.

Pavtube ByteCopy, which is developed by Pavtube Studio, provides easy but flexible solutions for archiving Blu-ray movie to PC hard drive. It lets users keep multiple audio tracks and subtitles when ripping Blu-ray to MKV container, these audio and subtitles can be a exactly copy of original streams, or transcoded ones (e.g. TrueHD/DTS-HD audio to Dolby Digital 5.1, PGS subtitles to VOBSUB). The latest update includes forced subtitles and external subtitles, making Pavtube ByteCopy v1.5 a considerate Blu-ray subtitles converter.

Is it a freeware for Blu-ray/DVD ripping? No. The ByteCopy is priced at $42. Is it a freeware for extracting .srt subtitles from Blu-ray Disc/BDMV/BD ISO? Yes. The subtitles ripping feature is not blocked in the ByteCopy trial. BTW, the trial is not time-limited, you can use it for lifetime as long as you like.

Note: A Blu-ray Disc Drive is required for reading Blu-ray Disc. The computer networked to get the app work- accessing BD+ key to crack the BD copy-protections.


How to extract .srt subtitles from Blu-ray Disc/BDMV/BD ISO:

1. Load Blu-ray Disc from BD-ROM, or BD ISO, BDMV from hard drive.

2. Find the “Tools” menu, and select “Export SRT subtitles” from its drop-down list.

3. Select subtitles by language. Check any language you’d like to keep. You can either keep native-language subtitles only or multiple subtitles in different languages.

4. Click “OK” and ByteCopy will extract Blu-ray .sup subtitles and convert them to .srt format. It could take long time to convert .sup subtitles to .srt, as .sup is a image format.

ByteCopy uses OCR (Optical character recognition) to read the Blu-ray image subtitles. Additional font object libraries for Latin-based languages (English, French, Spanish, etc) and Asia languages (Chinese, Japanese, Korea) are included to ensure subtitles be recognized and converted correctly. But there could be a few spelling mistakes existing in .srt subtitles, though ByteCopy does better than many other subtitles converter apps per we tested.

Thumbnails (here I rip .srt subtitles from The A-Team Blu-ray, which contains forced subtitles) :

And you see, I get 1 Spanish and 3 English subtitles for the Blu-ray movie The A-Team.

The A Team_1_1_English.srt – movie dialogue
The A Team_1_3_English.srt – commentary track
The A Team_1_4_English.srt – forced subtitles (which displays only when a foreign language is spoken)

    It crashes everytime when you try to make the external subtitle.

      I bet it does crash with some Blu-ray discs, but most of the time it works per my experience. Note that you should never use ByteCopy with DVDs.

    Many blu-ray disks have a subtitle track has 2 purposes:
    show all subtitles
    show forced subtitles
    the forced ones are present in the same subtitle but have the forced flag set to Y.
    In your example, the forced subtitle was a separate track. That’s very easy then to extract it and many softwares can do the same.

    Here is the tricky one:
    “Flags of Our Fathers” has a subtitle track that serves full subtitle and forced only.
    After loading the Blu-ray structure, ByteCopy would list the following:
    main title
    |__audio 1
    |__Audio 2
    |__subtitles English
    |__subtitles English (forced only)

    This is where I couldn’t find a way to use ByteCopy to extract both the full subtitle on one SRT then another SRT that contain the forced ones.
    In tools>preferences>subtitles there is a check box called “Forced subtitles only”
    I did one subtitle extract with the “Forced subtitles only” checked
    then I unchecked the “Forced subtitles only”, restarted the programme
    I did another subtitle extract.
    unfortunately the 2 SRT were identical :-(
    So ByteCopy is not working on this blu-ray
