CatBus, I posted the scripts that you want in the first few posts. Try those.

althor1138 said:Of course it would be better to encode the video and then mux in the audio later so as to avoid re-encoding but anyway here's how to do it in avisynth:

PAL=mpeg2source(palgout.d2v).assumefps("ntsc_film",sync_audio=true).killaudio()

NTSC=mpeg2source(ntscgout.d2v)

audiodub(PAL,NTSC)

You don't need sync_audio=true or KillAudio() because MPEG2Source() processes only the video and because the script does not envisage using the PAL audio anyway. Moreover, "NTSC" needs to point to an audio stream if you want to use AudioDub().

NTSC=WavSource()# or NicAC3Source() or whatever

But as you mentioned, the audio can be added on muxing. All CatBus needs to do is apply the scripts given earlier in the thread.
