    NTSC DV converted to 24p - How?

    I took a sequence created in a standard NTSC 16x9 timeline and wanted to convert it to 24p. I'd never tried this before so I thought I'd just create a new sequence and specify a custom format of 24 fps, 720x486, 16x9 with no interlacing. This automatically changes my fuse options to MPEG2 (or uncompressed).

    Super, I thought. Selected the MPEG-2 fuse/render codec. I then drop the sequence from the NTSC 16x9 timeline into this new 24p timeline and fuse the sequence.

    Everything was ok except that when I play the result, the video runs faster than the audio (24/29.97 to be exact).

    This surprised me because I thought LE would make the appropriate transformation (sort of the opposite of the 3:2 pulldown from 24p to 29.97i).

    I'm not much of an expert in this area and was hoping for some help from any of you whose do this sort of process in an effort to create a film look (or to transfer to 24p DVD, for example).

    Sorry about the long-winded explanation. Any help is appreciated.

    Cheers

    Re: NTSC DV converted to 24p - How?

    Without getting too deep into the technicalities, there are no pulldown tools in Liquid.  This is what alot of us are bitching about.  You're stuck to NTSC or PAL.  You do have a 24p timeline but in order to use it you must encode to a 24p codec (DivX or WMV) from within Liquid.  You can not go to NTSC (29.97) from a 24p timeline in Liquid.  Sorry....  (for you and me)

    Re: NTSC DV converted to 24p - How?

    Thanks for the reply, Stephen.

    Actually, I was hoping to go from NTSC to 24p - I know this sounds strange, but I was looking at a product called DVFilm Maker whose business is taking your NTSC or PAL videos and preparing them for 35mm film. In that process their product must deinterlace the 29.97 NTSC and then process it into 24p.

    I was hoping that I could go that far with LE. The next step is to take the 24p and do a 3:2 pull-down back to 29.97 (I know LE can't do this part).

    I could also take the 24p .m2v files and use them directly in, say, Adobe EncoreDVD to create progressive 24p DVDs.

    Alas, I'm missing some portion of the puzzle...

    Cheers

    I am familiar with DVFilmmaker.  In that case you could cut to 29.94 and fuse AVI (compression of your choosing) and then run it through DVFilmmaker as the final step?

    Sounds right to me. I wish I could see the difference between DVFilmaker and doing it in AE (24p cut conversion - 4% audio adjustment). DVF claims alot better of a picture, and nicely priced.
