subs and non-standard resolution

[elios]

I have authored dvd from dvb recordings with subtitles.
In case of non standard resolution video, e.g. 480x576
or 544x576, playing the dvd files from hdd, subtitles
doesn't fit into the screen ,seeming as they were
expecting a 720x576 resolution. So I thought 2 solutions:
1- convert video to standard resolution before authoring
2- define a boundary for subtitle display area according
to horizontal video resolution, e.g. for a 480x576
video, with DVDlabpro I defined margin left 40 and width
400 for subtitle area.
Method 1 have works, and may give a standard dvd, but
requires time to recompress (more or less equal to movie
lenght with Mainconcept Encoder) and a little loss of video quality
Method 2 works with software dvd player, subtitles are
correctly displayed horizontally centered ; but my
dvd-divx Amstrad standalone player they are displayed on
a smaller area on the left.
It seems software and hardware players have different
ways to render subtitles.
I would like to know if anybody have experienced similar
problems.

If you can demux subtitles in the form of ifoedit sup file then using this guide (http://forum.doom9.org/showthread.php?s=&threadid=82605) you can resize and reposition subtitles for final authoring with ifoedit. Since cropping invloves the use of SubRip that cannot handle sup directly, first you need to produce VobSub subtitles. Easy again with ifoedit. Just load some short m2v file along with sup and author to a vob file. Then use VobSub configure to extract subtitles to sub/idx files that you can load in SubRip. Proceed with cropping, etc.

Thanks:cool: I've never worked with idx/sub, it's an interesting approach. In this forum I also found an alternative to srt2sup which allow to redefine subtitle area in .sup format.
Nevertheless, I can confirm the different behavior of hardware and software dvd players:confused:
