Should all SVCD be NTSC-film? (even if the source is PAL)

[tempo]

Hello!

Since I never make interlaced SVCDs, I'm wondering whether I should slow down the fps of my PAL sources from 25 to 23.976 and turn them all into a more space-economic format, NTSCfilm... and I never gonna make a PAL SVCD again.

The idea looks good but I'm worried that it's too good to be true. Can anyone tell me if there's something wrong with the idea?

And 1 more question, I'm going to use VirtualDub for the slowing-down of frame rate. Is avisynth a better tool to do this job? and how is it better?

Thanks!

If you live in a PAL region then encode to PAL. If you live in an NTSC region always encode to ntscfilm if possible.

Converting PAL to ntscfilm is easy, and you can use VirtualDub, avisynth or TMPGenc (enable the "do not framerate convert" filter). Just make sure and also adjust the audio separately. BeSweet has built in options for regional format conversions.

But you are not going to gain any quality benefits converting PAL to ntscfilm. PAL is simply sped up from film, as opposed to adding new frames like you do with an NTSC conversion. Its those extra frames that eat up your bitrate. So like I said, if you live in an PAL region than just encode like that.
