    How does forcing NTSC 29.97 fps affect the encoding process.

    I have a DivX movie that has 24 fps? will forcing 29.9 fps make the movie better. Less jerky I imagine. I just dont understand how forcing it works.
    I can see going down from a 29.97 fps to a 24 fps. That would make sense. I wonder how it works exactly, or if it works to the better?

    Ok, I just converted a 24 fps movie, and forced 30 fps. It seemed to have made it worse.
    Is there a way to fix this problem?

    ok, this is what I got.

    a dvd rip with 24 fps. audio 192 kb.

    I got the CCE trial version and would like to know the best way to convert it to dvd.
    Do I ineterlace it? or deinterlace it? not sure what template to use to get the best quality and what modifications should be made to get good audio and 30 fps.

    Hi there,

    I use DivXtoDVD all the time, and I always force everthing to NTSC (29,97 fps).

    The results are always nice (on DVD Rips).

    You have to realise if your going to convert a MPEG1 or some small 320 x 320 video, you can't expect to have the output look like a DVD :)

    I think the problem might not be the fps conversion, but the file Ratio, converted to DVD 780 x whatever DVD is :)

    My 2 cents...

    See the threads on converting between PAL and NTSC in the Software Discussion Forum. There's lots of info about frame rates, audio sync, and links to guides etc..

    K, I tried out AVisynth, but it seems very difficult to use. I would take the time to learn it, but I would like to get some feedback, of whether it is worth learning and using to properly convert PAL AVI to NTSC DVD. Also, if the quality is that good, better than before, without no jerkyness. Anyone?

    Can you check those XVid numbers again? If the video is really 195 kbps
    then it's gonna' look like crap no matter what you do. You have nothing to work with.

    Before deciding on your favorite technique to convert Divx/XVid to DVD get some decent source material.

    yep, it is, guess I'm scr*wed.
    I converted it to NTSC using the guide on PAL TO NTSC, and it turned out to be worse.
    Probably cause it went from a a dvd rip to xvid
    then xvid to dvd.
    then dvdtoavi,
    then TMPGEnc,
    then the TMPGENc author

    at least it didnlt go to dvd2one to compress, lol

    anyway, guess theres nothing you can do.

    Duplication of frames, I thought may have worked

    Well, I have seen a lot of divx look better when converted to DVD. I guess there's more video info(so I'm told) in a divx or xvid than an mpg
    with the same bitrate. So I regulary put divx through TMPGEnc and burn to a DVD+RW to watch on my TV. Seems almost like magic. But I guess there's a limit to what you can do. :)
