I have been trying to follow the progress of BD/PGS support for Handbrake for a while now. It’s something that has been request for a while on the Handbrake forum but hasn’t seen much movement.
Before, to get subtitles burn in, it took multiple programs to demux then remux the file to get the file, which could take an hour or more, just so that you could burn in the subtitles with Handbrake.
Well I’m happy to announce that there is now a new nightly out that will not only allow you to add PGS to you videos, but also allows you to burn in the subtitles. I haven’t been able to do a full test yet (in the process now), but I did do a partial test with MI: Ghost Protocal and it seems to work pretty good.
If your interested you can get the nightlies from HERE.
One thing to note though, with the new nightly, I did have problems getting it to transcode a preview, but the actual encode seems to work fine.
