Resizing subs to fit resized video

[atropos]

When a (PAL) video stream has been resized from 720x576 down to 352x576 or even to 352x288, how can I resize the subs to fit correctly, for example the .bmp + .son files for DVDMaestro?

Thanx,

You don't need to resize the subpictures unless you are switching from NTSC<->PAL :)

Some software players don't seem to like (or at leats they didn't in the past) subtitles + reduced res, though.

You don't need to resize the subpictures unless you are switching from NTSC<->PAL Re-size or simply re-position?

NTSC and PAL have different pixel aspect ratios so in order to get the size and positioning correct, yes you do need to resize.

In practice, it is possible to reposition and put up with the bad AR. So long as the subtitles are sighted - automatic positioning is risky because sometimes subtitles appear at the top of the screen, say.

Actually, based on a recent conversion experience, I was delighted to fin dout how easy it is to use "DVDSubedit" to adjust the positions of ALL subtitles and supertitles on the same DVD at one time...

Yes I agree it is not hard...I meant positioning is risky if the process is automated, e.g. part of an NTSC<->PAL conversion tool. The downside, apart from bad AR and incorrect positioning (it will always be off slightly), is that user interaction is required. The upside is less jaggy subtitles and no need to use a non-binary format :)

Thanx for the info guys.
