    Hi,

    Having a few problems with lip sinc (hope thats spelt right) :)

    I have a few tv episodes which I am trying to convert, they are in avi format. I am using Nero 7 (nero vision 4) to put three episodes onto a dvd. The problem is when it comes out at least one or more of the episodes have a lag in the voice to lips ratio.

    I tried using avi2dvd to convert each file to dvd than add 3 of them to nero again but the problem is still there, it also looks as though the picture jerks ever so slightly.

    I am using a 3.3GB, 1GB RAM, 256MB NVIDIA card, win xp pro, Nero 7.

    Any help would be most apriciated as this is annoying but only really happens when I try and convert more than one file at a time. If I do just one long movie avi it works fine.

    Thanks

    Rob

    ok update, have checked the avi files and all the audio and visual is in sinc.

    This error often occurs when the AVI's MP3 audio is VBR (like for music) instead of CBR.
    The solution is:

    1) open the AVI with VirtualDub
    2) set audio___full processing mode
    3) do File___Save WAV.
    Now the MP3 audio has become an uncompressed WAV and the VBR MP3 issue has disappeared.
    After that:
    a) if you use an authoring appplication you'd just to compress the audio to MP2 (which is CBR 224 kbps) and author the M2V video with the MP2 audio. You 'll have inserted in the bitrate calculator, that you would have filled a DVD-R with a movie containing a 224 kbps VCD audio.
    b1) if you're unable to do so, make an AVI containing MP3 CBR audio instead of MP3 VBR. You open HeadAC3he, load the WAV, choose 'MP3' as destination format, press 'options' a couple of times until you can choose 'alt CBR' as preset. After that WAV --> MP3 CBR (128 kbps CBR is the preset).
    b2) load the old AVI with VirtualDubMod. Set video__direct stream copy, do Stream___Stream List, Disable the old stream list and Add the new MP3 you just made. Then Save (F7). In few minutes you'll have an AVI with the same video and the new MP3 CBR audio you just made. You'll use it, in Nero.
