shifted subs when converting NTSC to PAL

[xp_eric]

Hi,

When I create a PAL SVCD from an American (NTSC) DivX (by checking the NTSC to PAL checkbox in the conversion tab) the subs I add by editing the AviSynth script as follows :

LoadPlugin("e:\dvd2svcd\textsub.vdf")
TextSub("E:\eDonkey2000\incomming\Movies\spiderman cd2.ssa")

the subs are not synchrone anymore. When I don't convert to PAL everything is okay. ssa subs are timebased so changing the framerate should effect the timing but it does !

can anybody shine a light on this ?

cheers,

;) Eric

Hi-

ssa subs are timebased

Think about that one for a minute. Yes they are. You convert the movie to PAL speed, and the movie becomes shorter, so the subs are no longer in synch. Convert the subs to PAL based 25fps before doing the movie.

Hi,

and the movie becomes shorter

I don't think the length of the movie will change but if it does that will surely be the problem !?

Can anybody confirm if converting from NTSC to PAL will decrease the length of my movie...

cheers

Hi-

Check the frame rate of the original DivX movie you're converting. Is it 23.976fps? And what is the frame rate of PAL SVCD? Is it 25fps? There is an approximate 4% speedup when converting from NTSC to PAL (assuming the NTSC DivX is Film based and the encoder wasn't a complete idiot). A hundred minute NTSC movie becomes a 96 minute PAL movie (95 minutes and 54 seconds, actually). But don't take my word for it.:)
