audio out of sync with video when converting avi to mp4

tombdean

I have an AVI file which plays perfectly in Windows Media Player. The movie sound starts about 30 seconds after the video starts.

When I try to convert it to mp4 (so I can put it on my iPod) using the IMTOO MPEG Encoder Ultimate software, the movie sound starts when the video starts, so the sound is effectively 30 seconds behind the video. Very annoying.

I've tried changing the video frame rate and the audio bitrate, but nothing seems to work.

Can this be fixed? If not, I'll be contacting support to get my money back.

Of course you can fix it.
Please modify "Frame Rate" on the right panel of the main interface. The default setting of this item is "Auto". Please enter a concrete number for it to have a try. I think you can try following numbers: 15, 23, 29.97,50 and 60 .Generally, one of them will work. Please highlight the item which you want to convert by our program before modifying anything. Please press "Enter "after you input the number.
And of course, you can have try on some other number which seems to be closer (I can give you some suggestion here) if the audio is a bit earlier than the video, you need to adjust the frame rate to higher value to speed up the video, if the video is a bit earlier then the audio, please set the frame rate to smaller value to have a try.
