View Full Version : Moving DVD subtitles

Having backed-up a DVD and changed the aspect ratio in the process (intentionally :)), the subtitles are now in a less than optimum position. What is the simplest approach to adjusting their height on the screen? Can this be done with IFOEDIT?

No, I'm afraid not... The position of the subtitles are stored in the subtitle streams inside the .vob files.

As far as I know there's no tool available, which can adjust the bitmap subpic attributes like the position values...

So the only way I can think of is to demux the PGC in question (with PgcDemux), rip the subtitles with Subrip (using it's OCR method) to .srt text format, make a new .sup file with SubtitleCreator or Srt2sup with the desired position and mux it all back together with MuxMan.

If your original disc had menus that you would want to keep, you can use VobBlanker to replace the old Pgc with the newly muxed one.

Not a very fast and elegant method, but as I said: It's the only one I can think of, I'm afraid.

No need to do OCR. In this thread (http://forum.doom9.org/showthread.php?threadid=90804) you can find my short guide to reposition the subtitles with dvdsuptools. Basically you use Subrip to save subtitles as bitmaps while cropping extra transparent background from them. Then you decode with dvdsupdecode, change some parameters in dvdsuptools text file and encode to Ifoedit .sup file with dvdsupencode.

Thanks both for your help. The job in hand doesn't call for this level of complication. I had assumed in my ignorance that it would just be a case of adjusting a variable or two, not demuxing, adjust and remux. I shall pass on this occasion.

But, although it works fine when played with a software player, some subpics are not shown anymore on standalone players.
This bug is present in the free beta and in the new payware versions (at least in the last one I used some time ago).
