Can't seem to get audio to sync

    Hello all,

    I've read thru all the topics in this forum's archives relating to audio syncing and I believe I have a framerate problem in that my .avi seems to start on sync and gets progressively worse, though it is hard to tell it is definitely a few seconds off by the time you see someone's lips move.

    I have tried twice using this site's "Copy your DVD into DivX5 format - Guide for 169 anamorphic movies". The first time using the Inverse Telecine (IVTC) Option and the second time not using it. Both produced .avi with out of sync audio but the non-IVTC was far worse.

    Here's a little info on the DVD in question:
    "Friday" 89 minutes,
    From DVD2AVI:
    Aspect Ration 16:9

    Frame Rate 29.970 fps

    Video Type:
    Starts as NTSC, then after a few seconds of previewing goes to NTSC 80%, then after a few more seconds goes to FILM 39% then FILM 50% then continues to climb and then stay at FILM 97 or 98% and finally to FILM 99%

    Frame Type : Flashes back and forth between Progessive and Interlaced

    Audio Format: DD 2/0 192

    DVTool yeilds a 1680 Kbits with a Movie length of 89 minutes and an audio format of 160Kb

    The video comes out great and the audio sounds good but they do not sync...

    As a side note, I am using Windows XP and if I right click on the finished AVI and go to the summary tab, the first avi (IVTC method) the Audio Duration is listed at 1:31:07 and in the second avi (non-IVTC) it is 1:31:29. But as I've noted, the movie is proportedly 89 minutes long... which would of course be 1:29:00. I am VERY new to this whole thing and perhaps the 89 minutes is the running time of the movie not counting the publishers intro screen stuff... But what happened to the other 22 seconds??

    What the heck am I missing?!?

    Any help would be GREATLY appreciated and thanks in advance!!

    When doing the DVD2AVI step, turn on the feature called "Force FILM" and see if that helps.

    I will certainly give that a try tonight, thanks for the advice!

    Could you possibly shed some light on whether it is interlaced or progressive as I noted in my prior post during the preview it justs keeps flashing between them both.

    Also what does a percentage in the type mean such as FILM 97% or NSTC 30% ?

    Again thanks very much for helping this newbie out!

    Basically if the FILM percentage is over 85% or so, you should use Force FILM.

    And for progressive/laced, can't remember the thing now. I think it has been answered earlier in the boards, try searching for progressive or something like that.

    Well I tried encoding it with the Force Film option per your suggestion and the audio still got out of sync...

    Should I perhaps try it again with the Force Film option and not use the IVTC?

    Would trying it as a progressive type instead of an interlaced yield any better results?

    Geez, I wish it didnt take so long to encode...

    Again, thanks for all the help!
