An ffmpegX question for major

[elreeko]

First off, just a tip of the hat to you on creating a great piece of software

There isn't really any good piece of software for adding subtitles to a pre-existing movie. In ffmpegX you have the ability to load subs into a movie that you are transcoding from one format to another. This works very well, especially when I am converting VOB files. What I was wondering is if it would be possible to set a function where you could just add subtitles to a pre-existing movie. For example, I have an mpeg svcd file and I have the subtitle file that goes with it. I want to add the subs to the movie, but I want to keep the same format (SVCD). Is there a way to do this? Maybe it could be set up as a stand-alone function like ffmpeg's mux and split functions under mpeg tools (if possible that is)?

Just wondering Thanks for any consideration.

The current SVCD subtitle capabilities rely on mplayer to "print" the subtitle on the image while encoding. In consequence, to add a subtitle this way you need to reencode. Reencoding SVCD to SVCD works, though you will lose some quality -as always when encoding-. "Real" SVCD switchable subtitles -could- be added at muxing step, but not all players seem to handle them, and the process of creating them is rather complex as they must be stored in bitmap graphics format, while most subtitle files comes in ASCII format.

Thanks, I was wondering if svcd > svcd would work.

If I check out the m2v file in vlc while the movie is encoding should I be able to see the subtitles? or does it burn them on later?

[major]

No need of vlc, as you may notice ffmpegX has a PREVIEW button to watch the output movie while encoding.

Major what is the pop-up list selections 0-15 next to the subtilte check box do?

[major]

It is to choose the subtitle number amongst all the subs which are available in the VOB or DVD.
