I'm using AVS Video Converter, and here is a capture of my settings:

The audio and video don't match after converted. Any suggestions?

.AVI is pretty old so it is pretty common that you get audio and video out of sync when using a variable bit-rate. I suggest you to try some other containers like .MP4 or .MKV.

If it doesn't help, please submit a support request at AVS web-site.

Thank you so much for replying.

I think the sync problem maybe due to the video code is H.264 and the audio code is .aac.

If the original FLV videos have no audio and video out-of-sync issues, then there may be some problems about the converter itself you are using now.

AVS products are for Windows, while iSquint is for Mac. Plus iSquint development was discontinued...

As far as I know, there are as many as four factors that cause the audio-video sync problem:
1. Improper sync in audio-video encoding or video formatting.
2. Poor sync during film production or editing, the film itself is not synchronized
3. Loose sync tolerances in the player.
4. Delay in the external decoder or receiver, such as improper use of conversion software.
If the original FLV video is in A-V sync, there maybe some problems when converting. So which conversion software are you using?
