Hi-

What are im doing wrong?

Pretty obvious, I think. Load the original 23.976fps subs.

Does dvd2svcd converse the sub to 25?

Hi-

Does dvd2svcd converse the sub to 25?

Well, kind of. It puts the subs onto the video, and then afterwards it converts the whole thing to 25fps. Actually, I'm not positive about that, having never done an NTSC to PAL SVCD conversion. I just figured that had to be the case, given what you said in your first post. But if you open up the .avs, you should see the AssumeFPS(25) line after, or below, the Subtitle line. If that's true (and I think it has to be), then I'm right.

Hi all,

Just a clarification, but not completely sure (I rarely use NTSC as input):

If I remember well, dvd2svcd does not (strictly speaking) convert the fps. It uses "AssumeFPS" (as manono says) but not "ConvertFPS". That means:
AssumeFPS (used by D2S):
- Change the total length of the video. It will be a little bit shorter, so audio pitch correction (in BeSweet) is also used by D2S to keep a/v synchronized

ConvertFPS:
- Really converts the video frame rate. It is very high CPU consuming (and needs some kind of deinterlacing, not sure, may be it depends on the source). Video length is kept intact, so audio pitch correction is not needed.

EDIT:
Results of convertFPS should be worse in terms of video quality, so IMHO a minimum change of audio pitch (usng assumeFPS) is the best solution.
Anyway, as I said, I do not have much experience with this kind of conversions
