How to fix audio video out of sync after conversion

Sometimes when you are converting video from one format to another, you may be experienced audio video out of syn after conversion.In this tutorial I'm going to show you how to fix it.

1) Download the Any video convertor.  
.It is totally free. There is ultimate version of that software, but free version is enough for this.

2)After installing Any video convertor and select the video file you need to be converted.
please not that, I was tested with flv into mp4 conversion and output mp4 video has similar audio/video syn quality like the original one. I didn't have oppurtunity to test with other video formats but I'm pretty sure,
this method should work for any video format if it is supported by this converting software.

3)Now go to edit --> options.. --> select video tab --> increase Audio/Video Sync factor ( Default sync factor: ) to about 40 as the following image

4) by increasing Audio/Video Sync factor to higher value you can have better quality output but remember that takes time to complete the conversion.

5) hmm.. that's all , don't forget to put your comment/feedback here :)  .
