Extracting and comparing subtitle tracks? - Blu-ray Forum

Dankk · 06-14-2020, 10:58 PM

I have a Blu-Ray copy of the movie "Accident Man" (2017). When I inspect the disc on my computer, I notice there are a head-scratching total of 4 different English subtitle tracks. (There are obviously more languages available, but there are 4 tracks just for English alone).

Two of these are actually English SDH and appear to be identical, according to MediaInfo. The other two are just plain English, which are the ones I'm interested in; however, these two "regular" English subtitle tracks are actually not identical.

According to MediaInfo, the first track has 2742 elements, and the second track has 2748 elements. A difference of 6 lines of text (?). So my question is, what in the world could be the difference?

When I insert the disc into an actual Blu-Ray player, the disc menu only gives me an option for a single non-SHD English track. So the other English track must be a "hidden" subtitle track that wasn't intended to be used.

Without having to sit through the movie in 2 different players at the same time, I'd like to extract those subtitles as simple TXT or CSV files, and then use a program like DiffChecker to compare the difference.

My problem is: What program can I use to convert the subtitles into this format, and compare them? I can get them into SRT files, or SUP files, but nothing else. The program "CCextractor" claims to be able to export as TXT, but this feature straight up doesn't work. There are also browser-based tools that claim to convert to CSV or TXT, but unfortunately they don't let me upload anything bigger than 30MB.

Any help here would be appreciated. Again, I just want the subtitles in a simple text or spreadsheet format that I can plug into a difference checker.

For the record, here's the MediaInfo for the tracks I'm concerned about. The first English track:
