    ... if my MPEG vidfile has variable bitrate audio?

    Is it an external audio source?

    The file is transcoded into the pc with a Haup TV tuner card...

    I deleted a segment with Avidemux, and it threw the audio out of sync.

    Then I found the Audio shift button, and got the right shift, but how do I save the shift? AFTER clip removal? BEFORE?

    1) MPEG video doesn't support VBR audio so I suppose the answer is that it does not - assuming that you are correct in calling it MPEG.
    2) You don't.
    3) Hauppauge cards don't capture VBR audio, but I am making an assumption that you mean that the file was recorded with a Hauppauge card. Your wording is strange.

    Can't help you with Avidemux questions. It could be a problem with the source though and not necessarily what you did.

    Thanks...

    The file 'Properties' says, 'Type; MPEG video', MIME type; video/mpeg', so MPEG is all I know for sure.

    Only question then is how/when do I save the 'Shift' (of audio)...

    Mediainfo and G-Spot will tell if mp3 audio is VBR. Don't know if it can for whatever you may have in your mpeg file, given that VBR audio isn't officially supported. But they are the tools I would start with.

    Shift is for moving the start point of the audio to be sooner or later that the original position. You can use Copy mode for both audio and video when using Shift. Just tick the box, enter an appropriate value to get your audio back in sync, and save a new copy.

    Yup - figured it out... Thanks!

    First the vid edit, and save, then the sync shift, re-save (I don't know if saving 2 edit functions at one time makes a 'lesser' quality file or not tho'...)???

    It came out nearly perfect, except for 2 segments that seemed to 'drag' a little, and another length with no audio................

    Is there a way to check the edited vid without playing the whole video? Is the a check sum process that does this? Or something like this?
