As I said I did work on your problem and came up with these settings based on the information you provided us :Here is what I did :
1) Loaded input file to QMC
2) Expert Mode
3) Input these settings for video ( 2 pass mode activated)
4)Input these settings for audio ( audio sync activated)
You can try these settings and see if they solve your sync problem.
also here is the profile :
Place it in the /profile folder (QMC directory)C:\Program Files\QuickMediaConverter\Profil
Load it directly from expert mode . ( New QMC functionnality)
You can play with the settings from there it will be much easier .
Also thank you for letting us know if it solved your problem .
Have a nice day
