I have seen a few posts about subtitles. Most talk about using titles, but I want to turn them on/off like on a store bought disc. I don't want to have two separate movies on the disc as I don't think I'll have room - i.e. one movie is slightly more than half the disc size.
I'm pretty sure commercial discs just use text files that include the words to display and timing information on when to display them. Can we create these in VPX? I don't see it in the documentation anywhere, if so. Alternatively, can we include such files in the disc authoring process somehow, if we use a third-party application to create them? Any recommendations for a subtitle app?
