[HELP] Audio/video out of sync in output

[retractOffer]

Hello,
I am trying to encode and deinterlace some PAL AVIs to x264 and I'm noticing that for the current file, audio and video drift out of sync towards the middle of the converted file. IM'd to Selur is a 10s slice (~minute 34) of the original AVI file (1h 25m) in which I am noticing the sync issue. Please also find the logs attached.

Thanks
