Subtitles and H.264

[SKuypers]

Hi,

I'm trying to convert some DVD's with subtitles but so far only with limited success. Extracting the subtitles to separate files does not work at all and burning the subtitles on the movie places them way too high (they're placed at about 1/3 rd from the bottom of the movie), no matter which position setting I choose.
I encode the movies with high bitrates and resolutions. I tried to keep original resolutions but for some reason the ratio was always screwed up after encoding if I did that so now I just go with suggested resolutions (which, with the chosen bitrate and size are usually higher then the original but I can live with that). Size of the output files is a bit less than 2 Gb (no audio encoding).

Cheers,
Stef

If you're burning the original DVD subtitles, then they are images overlayed with the video, so you can't easily move them like if they were text-based subtitles in SRT format.

Hi,

If the images would be cropped to eliminate the whitespace around them then it would be able to place them somewhere convenient. Right now there's just a lot of whitespace underneath the subtitles making them appear way too high.
I tried the SRT option too but the files that are produced are always empty.

Greetz,
Stef

All these suggestions involve editing the .srt files. As you already surmised, you need some way of editing the .sup file in the .vob file directly. If you have access to a windows box, you can use SubtitleCreator.
http://subtitlecreator.sourceforge.net/
It was origianlly made for converting .srt files into .sup, but as of version 1.8, also allows editing of .sup files directly, including colour and position data.
This may be able to run on OSX under darwine

You can also try pgcedit, which should run under darwine:

DVDSubEdit will also work.

You could also try editing the pgciti directly in OSX using MyDVDEdit, although that can get a bit hairy.

BTW, the .srt files you produce are empty because you don't have .srt files at all.
