Hey
I tried looking through other posts and couldn't find the answer I needed.  I'm pretty new to the whole computer thing so I don't even know if I am doing this right Huh I have WINAVI 8.0 and I am attempting to convert AVI files into something I can burn to DVD with microsoft xp.  I finally got the files to convert without the program crashing.  When I burned the video the image seemed to lagg behind the sound a lot.  Roll Eyes  I was so excited because I thought I had finally accomplished this seemingly simple task after about a week of trying to figure it out, only to learn that I had wasted another disk.

If someone could please show me a no brainer way to fix this problem that would be GREAT Grin

As for the unsync problem, first, please make sure that your source avi file can be perfectly played! Then, you can adjust the sync with the audio delay option on the "Advanced-->Adjustment-->Audio Delay". Please try that!
BTW, which format did you convert your avi file to? DVD or MPEG2?

The files are fine when I play them in windows media player.  It is only after they have been converted (.vob i think) that they are messed up.  I hope that answers your questions  Embarrassed

Also, under the advanced I don't have the options you listed, the closest thing I had was to select the audio bit rate ?

Always use the ZJmedia audio option when encoding.

Ever since I switched, I've had no sound problems.

How badly out of sync is it?

Is it just delayed or does it get progressively worse throughout?

It's a pretty easy fix with V-dub.

it's pretty badly out of sync.  I haven't watched long enough to see if it gets worst. 

What is v-dub? and where do/how do I use it?

I gave up on winavi and downloaded cucusoft.  It works for converting but not for burning  Roll Eyes

Thanks anyways for all the help.

"V-Dub" is Virtualdub.....which is a program that does all kinds of stuff (convert files...split/join files, change audio settings, etc., etc, etc.).

Simply Google "Virtual Dub download" and download the program from whichever site.

Then go here...

http://www.doom9.org/index.html?/virtualdub_procedures.htm

......and look under the "Manual synching" (which is 11th down in the list of procedures).  It will take you through the steps to change the audio delay, or,.......... if the audio gets worse as the video goes on, the framerate.  If this is too complicated, read below......



If it is just a delay or the audio is ahead of the video, what you will do is open the file.  Set "Video" and "Audio" both to "direct stream copy" (you won't be "changing" the video/audio, just fiddling with the audio a bit), then goto "Audio", then "interleaving".  Here is where you will find "audio skew correction"......there is a box where you can type in positive or negative (-) values.....depending on if it's delayed or ahead.

Check your video first......count how many seconds the audio is behind/ahead.  If it's only a few seconds, try using "500" or "-500" and then goto "File"......"save as AVI" and then go open the new file and listen to see if you got it closer.  If it is still off...just keep adjusting the numbers higher or lower.

If the video gets worse (you can figure this out by seeing how badly it is out of sync at the start vs the end....usually if the audio gets worse.....there will either be dead air at the end or the video will cut off while the audio still plays), goto "Video" and then "Framerate".....then look under "source rate adjustment" and first try clicking the circle that sezs "change so that audio and video durations match", then save it and listen to the new file.  If that didn't work, you may have to manually adjust it using the "change to" area.

Basically....if the audio is too short....you have to make the framerate smaller (you are making the video shorter, which will cause it to allow the audio to "catch up").  If the audio is too long, use a higher framerate.  It will show you the original framerate next to where it sezs "no change".  If your video is, say, at 29.97 frames per second, then change it to 29.87, etc., etc.

Sometimes....you will have both the audio delayed AND a bad framerate.  What you should do is first get the audio/video in sync right at the start by interleaving the audio so the voices match up at the start (they will still be badly off at the end), and then play with the framerate to make the audio/video durations match.  If you have the audio/video in sync at the start and get the framerate adjusted, it will all match up in the end.

Give it a try and report back.   Smiley
