How to encode NTSC in CCE?

[Vlcek]

Sorry for prolly duplicating some info/question, but cant find clear answer to my specific problem - and as I worked with PAL content only think its better asking here.

I have material in NTSC interlaced 29.970 prolly from pro DV cam. Need to encode it in CCE for DVD and im kinda lost in PULLDOWN settings. I know I should convert rate somehow to 23.97 but not sure what is best method. Just enable Inv 3:2 pulldown with Auto 2pass detection and its all? Or use any other utility before encoding with CCE? May be some function from avisynth to get better result than CCE?

Another question is about deinterlacing - im used to deint PAL stuff before encoding for DVD. Should I do same for NTSC? Usually using Avisynth with mvbob script and securedeint() function, worked fine for this NTSC video too as I tried :)

So any ideas/help?

You cannot do inverse telecine on interlaced video content. Therefore, pulldown is not applicable.

Another question is about deinterlacing - im used to deint PAL stuff before encoding for DVD. Should I do same for NTSC? There is no need to deinterlace. You can do interlaced MPEG2 encoding for DVD.

i think as long as you select the right FPS in CCE (matching your source) it will set everything the way it should (the pulldown etc., anyway)

So how to process video - just select 29.97fps in CCE and nothing from pulldown menu and let it encode?
Thought that with IVTC i get more bitrate for actual video?

Or use pulldown in CCE on interlaced video? When i did it on deinterlaced, i got some "interlacing" artifacts on random frames.

If it's truly interlaced 29.97fps, then IVTCing to 23.976fps removes unique frames, and makes it play jerky. Therefore, if it's 29.97fps interlaced, keep it that way. Don't IVTC; don't even deinterlace. With 29.97fps encoding, you don't apply pulldown.

neuron2 already said the same things. Did you not understand?

Thanx a lot for easy and understandable answer :-)
