Doom9's Forum - View Single Post - NTSC DVD (29.97 + 23.976fps w/ 3:2 pd) to 25fps x264

hello,
since this looks like the ultimate forum when it comes to Avisynth scripts I'm wondering what you guys would suggest me for the following project:

I want to encode a MPEG2 NTSC DVD with short episodes (each episode has an intro) to MPEG4 (x264) with 25fps.
The intro of each episode is in 29.97 and when the episode starts it switches to telecined film (23.976 with 3:2 pulldown)

So what should I do ? To convert without visible quality loss or stuttering and without the Audio (always runs in 23.976) running out of synch?

Using a motion interpolating frame rate changer to convert the intro to 23.976, then IVTC the rest with TFM().TDecimate(). ?

MPEG2Source("E:\video.d2v")
p1 = Trim(0,2459).SmoothFPS2(24000,1001)
p2 = Trim(2460,0).TFM().TDecimate()
p1+p2
AssumeFPS(25.000)
LanczosResize(720,576)

Maybe you guys have a better idea. Thanks in advance for your help.
