How to Add Subtitles From a Blu-Ray?

Post by Maverickmusic »

I am converting a Blu-Ray movie into a .mkv and then feeding the .mkv into Handbrake for my Apple TV, but there are foreign language scenes that I would like to add subtitles, from the Blu-Ray disc, to my final .m4v file. What is the simplest way to do so? I know that I need to burn in my subtitles into the actually movie but how do I go about doing so? Is there a way to extract the subtitles that are playing on the Blu-Ray so I don't have to edit subtitles that I could find on Subtitle websites?

No, you don't "have" to burn in subtitles. Handbrake and the ATV can handle soft and forced subtitles. You "can" burn them in, but you don't have to.

Blu-ray movies use PGS subtitles, which Handbrake does not recognize at this time. In general you need to:

Use Mkvtoolnix to identify the subtitle track in your .mkv
Use mkvextract to extract the PGS subtitles to a .sup file
Convert the PGS subtitles you extracted (.sup) into a format that Handbrake will read (.sub/.idx) -- I use BDSup2Sub (4.0.1) for this
Mux the new subs into your .mkv file (the .sub/.idx output) using Mkvtoolnix again
Process through Handbrake which will now see the subtitles

On the last step, in Handbrake, is where you can make the decision to force the subtitles or burn them in to the video. If you do the latter you're altering the video stream and it can't be undone (without a new re-encode). So be sure that's what you want.

Mkvtoolnix, the same one you use to identify the PGS subs. You can insert your .sup/.idx and have it mux you a new .mkv to process through Handbrake.

I edited my earlier post to hopefully make it a little clearer.

Okay so now that I have had some time to sit down and attempt to figure this out I have run into a problem, I was able to extract the subtitle I needed but it's in .sup format. So I need to convert that, right? But I am on a Mac and can't find a program that will convert the .sup into the file type that I am supposed to feed into MKVtoolnix. Is there a program for Macs that can convert this file?

As indicated above, you use BDSup2Sub. Behold the power of Google...located here.
