Yes, that's apparent from your first post and I suggested a freeware alternative for you to try.
I've not had your problem with AVC, nor Super.
This is the only thing I can find in the AVC helpfile:
"Q: Audio tracks does not sync with moving pictures, why?
A: Please set "A/V sync" option to "default". It's recommended to close other programs especially anti-virus before encoding.
You can also click "edit --> options --> video", and you will find "default sync" control bar.
It's a factor to reach synchronization, the bigger value you move to, the better accuracy of sync you will get,
meanwhile, the encoding duration will also become longer.
Or, please add the video to Kmplayer (see address in helpfile), and right click to check Media Info, then set the video framerate and audio sample parameters in AVC(ADC) according to the Media Info to try again."
